High sensitivity speakers for tube amps. It about balancing those signals.

High sensitivity speakers for tube amps Destination Audio NiKA may be your answer. Linear Tube Audio makes amplifiers that range in power output from 1-watt (yes, you read that correctly) to over 50 watts per channel, which is quite a range. Perhaps your friend might want to look at Decware's own speakers. and on and on. Why You need PSE, if You will use speakers with High sensitivity? Like many tube amplifiers, the LTA Z40 integrated is better suited for higher-sensitivity speakers. This is sage advice. By baronkyle December 31 (40 hz or so) and tight (non resonant) bass. Thread starter cbn700; Start date Highly sensitive speakers (eg, horns) will tend to offset the power limitation, and SETs usually sound more powerful than their measurements indicate, but the laws of physics still apply: 2W is 2W, regardless of the kind of amplifier that produces it, and an amplifier's manner of clipping and recovery from overload take us only part of the way toward achieving greater volume. Some fairly low sensitivity speakers with moderate impedance curves and phase angles can sound quite decent with tube amps if you’re not into Motorhead. (µ/ý X¤, šª­N3 FȬ š ºÙó‹Ö/°¦ ± +œÍö@ —_ € ö-y[—íjÚ $7‘ ô®© ² ¾ že ]×Nú) ^æt ét ³š¯– šÎKËÇã9ü¥éÞ­ P× Ó›Î˯Çï+!bœ« ËXúË ³ Don't worry, you will come around. It’s important to not High sensitivity speakers play well through low wattage amplifiers . The decibel scale is logarithmic – a difference of 3dB represents approximately twice the power. I really like this approach for bass, even though there is a sensitivity penalty compared to a back loaded horn. Which usually tend expensive. In addition, there is a high impedance Higher sensitivity: Speakers with higher sensitivity require less power to produce the same loudness level as speakers with lower sensitivity. Melody50 likes We will explore the qualities of high-quality tube amp speakers and debunk common misconceptions surrounding sensitivity and efficiency ratings. Solid State Amps. A tube amplifier can clip and one will never know it whereas when a SS amplifier clips it will sound terrible. The tweeter is a 1" (25 mm) silk-dome tweeter that uses a double-magnet motor system and is gently loaded by a waveguide. Famous tube amps from companies like Fender, Marshall, Vox, and others have come to define the sound of virtually all electric-guitar music. If a tube amp is able to act as a voltage source, it will employ feedback (SETs usually do not) and will cut power in half as impedance is doubled rather than doubling power as impedance is halved. I use this with Analog records and 3 different high end earphones. Last The new Elekit TU-8200 tube amplifier kit looks quite tempting. I listened to the OBX-RW model at the same show driven by a single-ended 300B amp and the results were fantastic. High noise and highly-sensitive speakers is probably going to mean hiss. New posts. Member. I was looking at the Klipsch Reference R51M`s as they advertised 93dB. All else being equal, an amp pushing multiple speakers will sound louder than if it were pushing just a single speaker. However that said, the Heritage speakers are still among the highest sensitivity speakers I’ve seen independently tested. distance. I use the amp to power a set of carefully set up Avantgarde Duo v. Go figure. Posted: 14 Aug 2011 11:05 pm . More, the reason I’m not just searching the forum is that there have been some recent upgrades to both, and also because there was a recent thread about high sensitivity speakers and low watt tube amps. 8m) from my listening position and can't be more than 50cm from the front wall. Therefore, to maximize enjoyment with highly efficient speakers, may folks want to make sure that first watt is as clean as possible. 75, 3. Melody50, Jul 29, 2023 #1. Far from it: Jadis has a commitment to low-powered single-ended tube amps, represented here by the SE300B monoblocks (£6498 each) and partnered with the newer £8498 JPL MkII tube preamplifier, while DeVore What exactly, beyond ability to run on lower power, are the sonic differences between High Sensitivity and low sensitivity speakers? Something like A Tekton Lore/Perfect Set 15, Zu Omen/Decware HP-1 Radial allows me to run with a Specifically, sensitivity is a measurement of how loud a speaker will be from one meter away, driven by one watt of power. So I'm guessing tube amp + high sensitivity speakers (perhaps horns) and solid state + low sensitivity speakers? I'm also guessing hooking up a high sensitivity speaker to my 1971 Kenwood receiver with 40W/channel would probably sound bad? Thanks for the responses. Joined: 17 Sep 2009 11:15 am Posts: 60 Location: Houston The ideal speaker for flea power SET tube amp fans would be 1) affordable, 2) easily driven to room-filling The rule states that for "average" listening spaces an amp/speaker combination should be capable of producing at least 102 dB. The Feliks Audio Envy 300B tube amplifier is among the best on the market. In other words, they sound a little different with each speaker. Speakers with higher sensitivity aren't better than speakers Incidentally, high sensitivity is a very misleading term. Einstein Audio's initial offering in 1990, a solid-state amplifier called simply The Amp, was an immediate critical and commercial hit that remained in the company's product line for six years. If you like the body and "soul" of tubes and are interested in the CM1's, I would be more inclined to do a tube preamp and a smooth solid state power amp. 1 Like. In theory the higher the sensitivity, the lower the wattage needed. That Luxman is an SET amp. At 104db/watt/meter the M19s sound very good, top to bottom. Here's another fun fact low in impedance, their average impedance is good with valve amps. Speakers impedance dips require more power thus clipping does not necessarily occur at full volume. Joined Feb 15, 2021 Messages 23 Likes 18 Location Kolkata, INDIA. You might check out Zu Audio or Tekton speakers, tend to see them mentioned for use with tube amps due higher sensitivity. two 8” custom built . 97 dB. My Dentons are only 86 db sensitive which is a bit on the low end of scale. That would be good for up to 110 dB SPL, StereoGator - Snap Up the Best in Audio Equipment Paired with the right high-sensitivity speakers, well-designed SET amps can even deliver solid, tuneful bass. I am well aware that pre-amp and amplifier gain structure can result in CRAZY amounts of hiss from the speakers if you don't setup things correctly. In most loudspeakers especially high sensitivity ones some of the apparent sensitivity is output from the random ringing of the cones. The prevailing wisdom is to match a speaker to a low watt tube amp you want to be in the low to mid nineties. The ear is far less sensitive to the lower orders. There is something to be said for synergy. Classic Car Guy likes this. 99dB = 16 watts 102dB = 32 watts This is ancient. With the high sensitive speakers, I ordered the X9 for the know characteristic of SET 300B ability for vocals, without the chance to listen, We often hear comments about amplifier X does not have sufficient power to drive speaker Y or speaker Z requires minimum 200W to come alive. Generally any speaker with impedance above 10 ohms should be good, unfortunately high impedance speakers are not as common as low impedance types. I can get Tube amps are generally less tolerant of speakers with high phase angles (where the voltage waveform is no longer in phase with the current demands) than well designed solid state alternatives. I bet they would be great, but glad you have an option to return them. 1) solid state amp + low efficiency speakers 2) tube amp + high efficiency speakers Then there are all the greyer areas that lie in between. Hi I'd welcome suggestions for high sensitivity speakers that would work well with fairly low powered, if not quite flea-powered, tube amplifiers. All I Some of the higher end darTZeel inspired amps are rather excellent though they’re certainly not cheap. Loverly sounding speakers especially from their twin 10inch Bass drivers. High distortion means I prefer high sensitivity speakers since I love my low watt tube amps, 45, 421a, etc. jae Major Contributor. 5 watts and requires speakers of at least 89db sensitivity if I remember right. The heart of the Z10e is the highly-acclaimed ZOTL10 power amplifier, using sweet sounding EL84 power tubes providing 12 tube watts per channel. Single-driver loudspeakers are almost always high-impedance, high-sensitivity designs without a with its shelves of warm, glowing tube amplifiers, Coup de foudre Audio, is a hi-fi Omega’s loudspeakers can work Nice system so far and good to see you have some decent, high sensitivity speakers. Speakers with high sensitivity for tube amps. present a "manageable" load to the amp. Tube amps have traditionally had low damping factors. I have been quite satisfied with all tube amps over the years, range of 25-45 wpc. Indeed, a buddy of mine who has very sensitive wide baffle speakers (not Klipsch) runs things as low as 8 wpc up to 75 wpc and the speakers always sound great. Schiit Aegir is the only recommended Schiit amp for Zu's . The Klipsch Heresy would be the best choice from the 3 selections. , crossover before the amp). I am trying to figure out if there is a correlation between amplifier power ratings and speaker sensitivity in the prevention of over-driving of speakers when listening at high volume levels since stressing an amplifier beyond its Much more depends on an amplifier's power supply, slew rate and circuit design—including the function of transistors and voltage 'headroom'. High sensitivity (93dB+) and high impedance (8ohm+) across the entire frequency spectrum with minimal phase angle shifts are absolutely critical for tube amp matching, including the R8. The amp supplies 6. Our amps do generate higher ordered harmonics like any other amp does, but Without reference to specific makes and models, I understand that suitable loudspeakers for tube amps need to have two specific "virtues". With mid I had a thread in the tube section where I got a lot of advice on finding my tube amp and started talking about the choice of speakers. Before they pull the trigger there, they need to find the best higher sensitivity speakers they can, hopefully at $2k or below, new or used. My Jadis Orch Refer rated at 40 watts, blew out the water a Rotel ss amp rated at 100 watts. What are the major contributing factors here, if I may inquire, please? Any speakers with 95dB or higher sensitivity. Delivering much higher power than solid state amps with the same The Reisong A10 amp comes with a protective tube cage to prevent damage to the delicate components. I shopped for months for tube amps that could push 50watts or higher because I was using very inefficient speakers and believed that needed to be the bar. The Amp puts out about 15 Watts pure class A output. actual @1 watt input. Before they pull the trigger there, they need to find the best higher sensitivity speakers they I had a pair of their Hoyt-Bedford standmounts, followed by Omega XR8s, some years ago when I had a 300B amp in my second system. Omega would be another speaker with higher sensitivity. All speakers have a rating of how well they turn power into sound, expressed in the number decibels detected, given an input power of 1 watt and measured at 1 meter away- shortened to Both the amps you have there are low wattage amps and need very high sensitivity speakers. A lot of advice was given to me on the need to have high sensitivity speakers. With the TU-8200 tube amp kit and THE MYTH"Tube amps require special speakers that tend to be very expensive. When people come over you tell them, I've been on a quest for a reasonably affordable, great sounding pair of bookshelf speakers for my low watt hi-fi tube amps. "The truth is, While most speakers are nowhere near as sensitive as these KLIPSCH models, there are other high sensitivity speakers readily available on the mass market, made by companies such as TANNOY, JBL, High sensitivity is great, but it doesn’t tell the full story as to how well the speaker will react to the amp. Many speakers with high sensitivity ratings are poor choices for tube amps, just as many speakers with low sensitivity ratings often work quite speakers that will sound best on a current limiting solid state amplifier is a similar process to How can these low power tube amp drive these speakers? For example, the LS 50 metas spec sheet says "Recommended amp power: 40W - 100W) As miller aptly stated the true and most important spec of a good speaker is it's sensitivity, and, the higher, the better. My bet is they’re probably closer to 92db in reality but that should still suffice. These are tube amps with one rated 35 wpc, the other 65wpc. 0. Still, good point and I suppose the best spanking for me would be for this to be the last comment in the thread. If the power is needed to reach reference levels that a receiver can not do than an amp is needed. I'm not sure if I see the reason to do that at all. The speakers are individually hand built in New York City and are listed at about $12,000US. An ideal speaker for a tube amp would have a flat impedance and phase angle at all frequencies. Desperately need advice about small, High sensitivity speakers to use this Amp to it's full potential. I hope that one day Berning will update the "Siegfried" design, and then add it to the which to me sounds like it delivers a more direct coupling of output to speakers than available with the traditional tube amp Tube pre --> SS amp --> sensitive speakers = easy meat Tube pre --> Tube amp --> sensitive speakers = musical easy meat Tube integrated amp --> sensitive speakers = theoretically optimal, no worry over impedance matching. but currently also have an Ayre EX-8 2. What I liked most about the TU-879S tube amplifier was the seemingly endless amount of tube combinations that were possible. I have found 5 watts to be the sweet spot with tubes and 25 watts with a SS amplifier. I also have one pair of speakers that sounds good with whatever I connect to them. Low and high frequencies are boosted compared to the midrange level, though the treble can be fine-tuned by experimenting Magnavox made several amps powered by the 6BQ5 vacuum tube. (which I will be pairing with a lower sensitivity speaker like a PMC DB1 gold or a Legacy Audio Monitor HD. OTOH, tube amps don't do this at all- in particular SETs. In my experience the KT88 tube is better for higher sensitivity speakers. The Forte IV reached 95. Since they have built-in amps for the woofers they don't tax the tube amp and the clarity of the mids and treble is very good without sounding harsh which almost all "high" sensitivity speakers seem to me. Low wattage single ended tube amps definitely have a sonic signature and if that is preferred one has no choice. One is high sensitivity, in view that tube amps have limited power Second is they need to have a smooth impedance plot and avoid low impedance valleys - i. Even with bsc (which it demands Art's ATM-1S was a step in a long succession of tube amplifiers produced by AirTight since its 1986 founding. It’s important to not Like @trd says, as important as the sensitivity is the speaker's impedance curve. Those Alluxity amps you've got your eye on are high-powered for your sensitive speakers, so I don't have a reference to comment with anything like them, although I am curious how they would sound. Feb 26, 2021; Thread Starter I am having a hard time finding speakers with very high efficiency rates like the CF-2. I have been listening to my Decware 300b tube amp for a few months now. Usually if you are in a teeny room and sit close to the speaker, or if you have high sensitivity speakers. Any recommendations? (12 inch instead of 15 inch woofer), but sounds wonderful with a tube amp of say 20 to 35 watts. I'm currently waiting for my recent purchase of a Musical Paradise mp301 mk3 integrated tube amp. and they were pretty sensitive because a few watts was all most had, and 25 W/ch was a "big" amp. To help guide you, below is a chart listing all of our amps and our recommendations for speaker sensitivity pairing. I use a Poindexter inspired PP 6V6 with around 6 watts output. Integrated tube amp (maybe 300b) - like an Earle Weston I do appreciate the advice, but yes, I really do have it narrowed down to the This is a review and detailed measurements of the Dynaco ST-70 Series 3 tube stereo amplifier. McLover, Sep 2, 2022 #7. First came the original ATM-1; AirTight has also produced the ATM-2 (which used KT88 tubes), the ATM-4 (6L6GCs), the 1S that Art reviewed (EL34s; the S stood for "special"), the ATM-2 Plus, and now the ATM-1 2024 Edition ($14,975). J. Reason - a 95db efficient speaker can get pretty loud with one watt. Joined Apr 27, 2021 suggests that the XT 6's treble will be exaggerated with tube amplifiers that have high output impedances. Movies at reference never peak more than 105 dB per speaker and doubt it is ever recorded that high. In addition to speaker sensitivity, other important factors are the size of the room (H x W x D), and how loud you listen, and if you use a subwoofer to off-load work from the main amp and speakers (i. Which speakers specifically have that though? I've been speaker shopping for low powered tube amp and here's the BIG problem. WoW – what a beautiful sounding amp! No other vacuum tube amplifier in this price category touts, Pure Class A in Pentode & Triode mode. It's my understanding that tube amps really need speakers with a high impedance (or at least relatively flat impedance curves) as well as a high sensitivity (due to typically low wattage output of the amp). I think there is merit to Almargs observation that flat impedance curves may work similarly well with both tube and SS. Overall, the Reisong A10 EL34 Hi-Fi Audio Stereo Tube Amplifier is an excellent choice for audiophiles seeking a top-of Folks, I have been doing a lot of reading on both integrated SS and/or tube amps. No Ultralinear operation, you do not want ultralinear operation I was a little nervous to It’s always fun reviewing high end gear. SPL peaks at a 1 M. C. Regards, S Hi everyone. 2. However on further research I discovered that apparently Klipsch are lying SOB`s and their speakers are no where near as sensitive : Linear Tube Audio makes amplifiers that range in power output from 1-watt (yes, you read that correctly) to over 50 watts per channel, which is quite a range. Some people like this because they find they are more revealing and transparent sounding, however they must be paired with an extremely sensitive speaker such as a horn speaker. Happy Turkey Day from a turkey! The Amplifier. Such sensitivity means, for example, that a pair of G12s in a 2x12 Vox AC30 can produce a lot of noise from that 30-plus-watts tube amp – even making it sound as loud as a 60-watt or 100-watt amp with less efficient I have a couple friends interested in tube amps, lower wattage -- 40 wpc or below. Using the same amp and preamp, and the volume set to the same spot, an 89dB efficient speaker will require more gain than a speaker rated at 101dB. Hi @doogie44 I too have a McChanson 300B Tube Ampand used to channel it through a pair of re-furbished and rare Wharfdale E90 speakers. If it's medium sized, 20-50W, something with reasonably high sensitivity, say over 90dB and a smooth impedance curve is a good bet For low power, 10-20W, Like @trd says, as important as the sensitivity is the speaker's impedance curve. Allows a much larger choice of tube amps. Tube power amps tend to interact more with the speaker load due to their higher output impedance. S. Hi, I would like to build a pair of high efficiency floor standing speakers. The Ref. It’s a truly high-end amplifier with an incredible sound. OP . The distortion at high power output is not as obvious in a tube amp. Fans of tube amps appreciate sensitive speakers. a high sensitivity speaker could present a very complex impedance while a low impedance loudspeaker might be a very benign load. 83V/m, though JA did note that the Volti's highish impedance makes the speaker an easy load for amplifiers. Most manufacturers Without reference to specific makes and models, I understand that suitable loudspeakers for tube amps need to have two specific "virtues". As I am now in the midst of the searching for speakers I am opening a thread here. Discussion in 'Audio Hardware' started by Melody50, Jul 29, 2023. To get the most out of a tube amp you need an efficient speaker, this is measured in decibels(db) as efficiency or sensitivity. SET amplifiers, which operate in class-A, typically produce watts in single digits, powering speakers with a single, low The tube setup I have is a DIY (on loan - I'm new to the tube amp world) setup pulled from an old Magnoavox cabinet, 4x 6v6GT with 7408 tubes. It is suitable for use with 10-100W high-sensitivity speakers, catering to all music types, and particularly Product: Ming Da MD300A - 300B tube integrated amplifier Manufacturer: Mei Xing - China Test sample kindly supplied by: Unless you use high sensitivity speakers (horns, fullrange etc. It costs a pretty penny but if you have the budget Hi, I have an Eico HF-81 that is currently Speakers for tube amps Speakers for tube amps. Parallel ECC83 is not good choice. Most bookshelf speakers are 86-88dB I guess due to smaller & single mid-bass speaker. Last edited: Feb 26, 2021. thanks. because I am very sensitive to The same speakers with my maggie 7wpc amp can be cranked up quite high. I have had tube amplifiers in the past and for the past 12 years, I am the proud owner of a BorderPatrol S20 parallel 300-B tube amplifier with dual power-supplies. My current system is 2 high power Carver amps feeding a set of Carver Platinum Amazing speakers. SS or tube. Lots of modern speakers depend on high power amps with high damping factors to manage the impedance swings present in the speakers. That being said, I keep coming across a strong preference for higher current amps as opposed to high power amps powering low sensitivity loudspeakers. Good Luck Paul Baton Rouge AIQIN is a well-known tube amplifier brand in China, and the EL34 series amp has already sold over 30 million copies. I noticed there is a 5 dB difference in sensitivity: 92 dB vs. Page 1 of 2 1 2 Next > Klipsch Heritage(know to me) for low watt tube amplifiers. The smaller of the 2, about $1500 complete. In the '50's and '60's they were a manufacturer of high quality amplifiers. They traditionally have both inherently high The DeVore Fidelity Orangutan O/96 is a 2-way design that uses a custom SEAS 10" (254 mm) paper cone woofer with a phase plug. This definitely will smear the music fed to the speaker. Taking the case of a power amplifier, low distortion and a higher noise floor may work well with less sensitive speakers. I have tried the tubes vs. QUESTION: What high sensitivity speakers would you recommend to them, new or used? What did you try and NOT like? A fantastic partner for high sensitivity speakers Installing a pair of efficient speakers is an even more amazing experience. If you are using a high gain source, high gain preamp, high gain amp and sensitive speakers it will result in high noise floor. Any suggestions on a high efficiency speaker kit to build and not break the bank? I have some low watt tube amps and looking for more efficient speakers, thought best bank for buck is to find a DIY kit. At 8 watts, I have them paired with Klipsch below their rated spec, Klipsch Heritage lineup included. my favorite pair so far is a custom built Omega called Vintage 8 High Output. This can be beneficial for those looking to achieve louder sound levels without needing a high One has to consider the way SS amplifiers clip vs tube amplifiers clipping. To help guide you in speaker / amp selection, we have developed speaker recommendations for each of our amps. Number of speakers. I run a Bob Latino ST 70 (Dynaco clone) with a 93. Colin Flood For tweaking audiophiles seeking the short route to audio nirvana with the delicious delicacy and tone of SET amplifiers, the choices for proper loudspeaker matches are limited. Understanding factors like impedance and phase angles will play a Speakers with higher sensitivity ratings (typically measured in decibels or dB) are more efficient at converting amplifier power into sound. Manufacturers OUT AND OUT LIE regarding sensitivity specs. Please don't start a flame war over this comment. With a tube amp, I'd really want to hear a speaker first before I buy it. It is important to note that LTA amplifier owners have found great enjoyment using their amps with a variety of speakers outside of the below ranges. tansand. The sensitivity or efficiency ranges of speakers vary from As you know, use of hi Sensitivity speaker, hi impedance is mandatory for small tube amps. So I'm starting to look at vintage speakers, picked up a set of Pioneer CS-A31 from another friend to play with but I'm always on the lookout for vintage gear. My speakers can supposedly work well with 300wpc, according to the manufacturer. It's enough one 12AT7 /ECC81/ in SRPP. Avoiding high power needs, SS or Tubes, keeps the initial cost down, lots of great vintage stuff, lots of competitive new stuff, reduced heat from tube amps, . So, as far as tube amps go, "sensitivity" cannot be used as a determining factor for selection of a loudspeaker. All the high- sensitivity speakers (EV, Klipsch, Lowther, Volti, Zu) are way too colored in sound! jasonbourne52. so if you are pragmatic, you design the amp so that higher ordered harmonic generation is avoided, while doing what you can to suppress the lower orders, as long as that does not hurt that lack of higher ordered content. 3A for example was measured by some Canadian testing facilility at 87. The amplifier is Sun Audio SV2A3. Most of these amplifiers use high efficiency speakers. The ZOTL40 Reference amplifier outputs 46 watts per channel into 8 ohms, and 51 watts per channel into 4 ohms. Current visitors. Reactions: DanielT. e. 2 Any floor standing speakers out there with 94-96dB efficiency that cost under $1K and, of course, sound good? Used is ok too. Tube amps typically have lower power outputs than solid-state amps, so high I have a couple friends interested in tube amps, lower wattage -- 40 wpc or below. 5 and 6 watts respectively). Menu Nobsound NS-03D Dual Mono Power Amplifier Tube/Valve Class A Single Ended EL34 8 wats (power amp) looking at 90, 91 sensitivity . I actually put my ears next to the horn and didn't hear hiss. I've used both an AHB-2 and an 8 watt/ch tube amp with fairly sensitive LaScala loudspeakers. And, less than high sensitivity speakers will demand more power for a standard listening level. Joined 2016. Sound is SO incredibly "Lifelike" I have a small room, listen to Female and vocalists and light classical music. Rumour has it Tony McPhee of the Groundhogs used really floppy fane speaker and poked holes in the cones with a pencil to get more speaker breakup! Discover Destination Audio's unparalleled collection of high-fidelity speakers, tube amplifiers, and audiophile-grade audio equipment. They are going to need to be fairly sensitive due to the low power of the amp. ) you're not going to shake the floor. High sensitivity changes all that. For this reason, the argument that only speakers with an impedance of 8 I see that is not easy to find good speakers for this little tube amp. And gain is enough for Your sensitivity speakers. Mar 14, 2021 #7 Many of the suggestions in this thread are the push/pull design that he is trying to get away from in the Primaluna. Knowing this I just gave away my old low efficiency Pioneer bs-21 speakers to my sister along with a cheaply acquired Marantz 6100 turntable. 2021-02 Also worth knowing is the tube amp's output impedance at the different impedance taps -- most tube amps have an output impedance of around 1 ohm and often considerably higher and they like higher impedance loads more than lower impedance loads. One is high sensitivity, in view Limited choices for High sensitivity speakers when tube amplifiers are in abundance. However, there's no denying that this is the real thing. the following receivers: Which brings another point: with a high-sensitivity speaker, While Volti specifies the Razz's sensitivity as 97dB, JA's estimate was somewhat lower at a still-high 93dB(B)/2. I have made it no secret around here that I am high sensitivity speaker fan and I love the sound of my Avantgarde Trio Omega speakers with 109db sensitivity (among the highest out there). 5wpc to 125 watt mono blocks with them. I just don't like the sound of high sensitivity speakers in general. Depends. Pentode tubes on Hi, my speakers (B&W CM1) have a sensitivity rating of 84db which i gather is very low. Also Klipsch speakers if I can add in a speaker instead of a headphone. With high sensitivity speakers, many prefer low power tube amps. 5 Sensitivity speaker and it sounds great. Not sure if any of the shortlisted speakers will work. Frequency response of 43Hz to 18kHz with a sensitivity of 95dB. SET amps on the surface seem to have the most distressing of numbers. I used to have 7 feet tall of amps thinking the same thing. This is where accurate reviews on amp-speaker combos are a good guide. new at factory site etc Why You will use prestage with gain more 100? Better tube will be 12AT7 with better sounding and less gain and more current, that define better sound, IMO. All three variables (slope of impedance, value of impedance, value of phase angle) together determine how good a match a speaker will be for a tube amp. So now that you have a fair idea of a speaker’s efficiency, you’d be eager to know the minimum threshold efficiency/ sensitivity rating for labeling the amp as a high-efficiency speaker. S. I know this is a very broad generalization and people will disagree, especially those owning higher powered tube amps. and "headroom" isn't a consideration. Every time I hear high sensitivity speakers with powerful amps, my ears start bleeding. Tube amps will deliver their power most evenly into a flat load, and with their typically higher than solid state output impedances, also work better with a higher impedance load often. No clear advantage either way in that case. sensitivity rating are appropriate in combination with SE 300B amps. 1. 1 John Parks Audioholic Samurai. Donations. Amp in center. I only like KT90 and 6550's,. But can work with less sensitive speakers depending on listening distance and room. It's amazing what 9 Be aware: When choosing speakers for use with low-power tube amps, the sensitivity spec is less important than finding a speaker with a flat, high, nonreactive impedance characteristic. Well I'll hear the 6550 first time in 2 weeks. Living Voice (based in the UK) also makes a number of high-sensitivity dynamic loudspeakers (~94 dB / W). Please let me know! Yuor help is appreciated very much! Best regards, Fabrizio . Hi, Any suggestions on what speakers (bookshelves or tower) that would be sufficiently powered by the Willsenton R8 amp? Preferably $1K or less. 5db. Details In the early days 16-ohm and even 32-ohm speakers were used to take better advantage of high output voltage but limited current available from tube amps. Reply. Members. There are less loudspeaker choices for SET amplifiers Now unlike solid state amps tube amps have a high output impedance and are basically a voltage source and not a current source, (yes even 2 ohms) and/or not too sensitive speakers if the room is small enough, Don't fall for the SE tube hype! PP tube amps can be just as good! And a lot more practical! I have both - and high-sensitivity speakers to use with the SE amps (Klipsch Heresy's). Speaker sensitivity. To gain a 3dB increase in Sound Pressure Level (SPL) you need to double the power 87dB speaker with 1 watt makes 87dB 90dB = 2 watts 93dB = 4 watts 96dB = 8 watts - you are at your maximum volume level with 8 watt amp. It about balancing those signals. Yelamanchili manohar Well-Known Member. What's new. A speaker with higher sensitivity will produce more volume with less power, meaning you can achieve a louder sound with a lower wattage amplifier compared to a speaker with lower sensitivity. The resulting figure is quoted in decibels. For tube amps in general, the efficiency spec is more useful on this account. The Spendor speakers mentioned by the thread's originator are unsuitable. Sorry: my thread title should have read "high sensitivity speakers with mid powered tube amps?" is mid-powered tube amps sound just lovely with sensitive speakers. 3 Likes. To varying degrees, we know that these amps sound different from each Many low-power SET amplifier aficionados look for speakers that could be a good match for their amps both in terms of proper high sensitivity and flat impedance curve and top-level performance.
