Given that you are into tube, maybe you should stay away from 86dB sensitivity speakers. Again, how loud do you listen to music? You might have to make some compromise depending on which is more important to you: the amp or the speaker. The common wisdom is: tube amp for high sensitivity speakers and class D amp for low sensitivity speakers. In my case, my speakers are Raidho td1.2 with 87dB sensitivity and my amp is AGD Audion mkiii with 100 watts per side. Sometimes I feel I could use more power but for the most part, it’s ok. 

Given the low sensitivity and that the speakers probably drop below 4 Ohms at certain points I think you’d be really pushing it with your amp.  There are lots of good speakers out there at that price point so I’d look for something else if you want to keep your amp. 

Hi Mamifero,

You have a great amp, but remember that tube amp power remains constant from 8 ohms to 4 ohms, unlike most SS amps. That does not mean your amp cannot drive 4-ohm speakers, however. In fact, assuming these speakers don't have a crazy impedance dip, they will likely sound great. Per the other post, there is no common wisdom that says tube amps cannot sound great with low-sensitivity speakers or that Class D is best. Try your amp, and then make up your own mind.

Agree with the above. If Cayin didn't mention the specs into 4 ohms, chances are the amp is not comfortable with that load. A lot of tube amps aren't. And with EL34s,  you likely aren't getting the same rated power as with KT88s.

Look at different speakers or a different amp. I wouldn't recommend that pairing.

Some useful information about amplifiers in the link associated with this recent A’gon thread (link to thread).

As others have said, not only are your speakers 86dB efficient (SPL @ 1M, @2.83V), but it is actually worse since they are rated for a 4 ohm impedance, which makes them only 83dB efficient for an input power of 1W.  As the impedance spec of 4 ohms is not clarified to be the nominal or minimum impedance, it could be even worse if the impedance drops further at certain frequencies. 

If you are still in the system building phase, then choose speakers that deliver the type of sound you like for the music you listen to, and then find the appropriate amplification that will adequately drive them.  As others stated, if you enjoy tubed amplification then look for medium to high efficiency speakers with nominal impedance of 8 ohms or above and no crazy impedance dips.  If you like the sound of 86 dB speakers with an impedance of 4 ohms (which is the rating of my speakers), then you need to have some power (i.e., current/amperage) to drive them.  Look for amplifiers that double, or nearly double, their output when the impedance is halved and that are stable into lower impedances.  Here is (a link to) a calculator that can determine the SPL output for a given power and speaker efficiency in W/1M (your proposed speakers are rated at 83dB @ 1W/1M so use 83 in the calculation).  Using the calculator, for your proposed speakers, an amplifier rated at 100w/channel/4 ohms will provide a SPL of about 95dB at a listening distance of 12 feet.  Figure out the sound pressure level you want to achieve and compute the minimum needed power rating for amplifiers you are considering.  I am not sure what rated power your Cayin will deliver into 4 ohms since it is rated at 8 ohms, but it may be 100 watts.

My amps do not quite double their power from 8 to 4 ohms, but they are rated at 650 wpc @ 8 ohms so even if they don’t double into 4 ohms there is plenty of headroom to drive my less efficient speakers.  In your case, I would look for amplifiers that provide at least 200 wpc into 8 ohms and that double into 4 ohms.  Using the calculator that gives you a maximum SPL of about 100 dB at full power.  Choose even higher powered amplifiers if you like to listen loud and then, even when not rocking out, the higher power can provide dynamic headroom to better handle musical peaks and to keep things from sounding thin.

Agree that most tube amps that can comfortably drive a 4 Ohm speaker will have 4 Ohm speaker posts or the amp’s transformer has different internal taps to wire to the binding posts.   
 

My Quicksilver amps have 4 and 8 Ohm posts.  My 300b amp has 8 and 16 Ohm taps … confirmation that it’s not a good match with difficult loads.

Often times a tube amp will put out less power with 4 Ohm speakers connected to an 8 Ohm post.  
 

Just picked up a pair of 6 Ohm speakers. They are 88dB sen and 50 watts wasn’t quite enough.  100 was a good match. 
 

 

your amp has 4ohm taps so just hook it up to those and you should be fine at low to moderate levels. 

Thanks everyone for your really helpful comments.

Indeed, the Cayin A100T has 8 and 4 Ohm taps, and I’m sure it can drive 86 dB speakers, however, since I couldn’t find information regarding its 4 Ohm output, I am not sure if it would have enough power to make those sound good and as were designed for; probably when they engineered these they had in mind those really advanced and powerful Technics amplifiers, or something similar. 

As a reference, I remember testing my old B&W 705 monitors with two different tube amplifiers. One was a 40 watt per channel and the other was this Cayin (70 watt per channel), and at the same volume level, the more powerful amplifier made a significant difference, it made the 705s sound more defined, in particular the bass was much better. So, I believe it might be the same with these Technics speakers, the Cayin will be able to output adequate power but I might be missing out their full potential. 

 

the Cayin will be able to output adequate power but I might be missing out their full potential. 

Bingo!

"Indeed, the Cayin A100T has 8 and 4 Ohm taps, and I’m sure it can drive 86 dB speakers, however, since I couldn’t find information regarding its 4 Ohm output,"

 

Tube amps do not increase power at lower impedances like SS amps do. The output transformer matches the output of the amp to match the speaker’s impedance so it’s still 70wpc out of the 4ohm tap. But this also functions to match the speaker’s impedance to the amp much better. I think 70wpc should be enough if you’re not trying to rock out at 100db. Technic’s recommended power is well within your amps power output. Recommended amplifier power: 40-200 W

It is a good question. If you are in love with the sound of the speakers....

 

Just a quick AI summary of speaker sound and of the amp’s ability to drive them.

 

Quick summary — what the Technics SB-G90M2 soundlike

• Very coherent, focused midrange with excellent imaging thanks to the coaxial (point-source) mid/tweeter—voices and instruments sit very well in the soundstage. (hifiheaven.net, Technics)

• Warm, musical presentation: a little more mid-forward and pleasingly full-bodied than some very “analytical” designs; tonality is aimed at musical engagement rather than bleached neutrality. (LB Tech Reviews, soundstageaccess.com)

• Good low-end extension and punch for a medium-sized floor-stander (specs show ~33–34 Hz extension), so rhythms and basslines have authority. (Upscale Audio, Guitar Chalk)

• Smooth, non-fatiguing treble — detailed but not excessively bright; in direct A/B some listeners find them slightly tamer on the top compared with B&W. (soundstageaccess.com, Witchdoctor)

• Dynamics and build: Technics tuned these with solid cabinet damping and CAE/CAE-style engineering; they respond well to capable amplification and present good dynamic contrast. (Upscale Audio, Witchdoctor)

• Electro-mechanical notes: lowish sensitivity (~86 dB) and 4 Ω nominal impedance — they benefit from a decently powerful, stable amp rather than a tiny bookshelf amp. (Technics, Upscale Audio)

How they compare with other speakers in the same price bracket

(typical competitors: Dynaudio Evoke 50 / 40, Bowers & Wilkins 702/703 series, KEF R7, some models from Focal and Monitor Audio.)

• Versus Dynaudio Evoke (and many neutral-leaning designs)
  Technics = more midrange presence and musical warmth; Dynaudio = a bit leaner/neutral and very transparent. If you want emotional, front-of-stage vocals, Technics often wins; if you want strictly “flat” response and forensic detail, Evoke leans that way. (soundstageaccess.com, Speaker Decision)

• Versus B&W (702/703 series)
  Technics tends to be less bright/forward in the top end and usually smoother on vocals; B&W can sound more “exciting” or forward and more detailed in the presence region, which some listeners call “bright.” If you’re sensitive to treble glare, Technics is friendlier. (soundstageaccess.com, AVForums)

• Versus KEF R7 / point-source rivals
  KEF (and some KEF models) aim for very accurate, neutral imaging from uni-Q drivers; Technics’ coaxial design puts emphasis on mid coherence and a warmer overall presentation. Imaging is excellent on both, but the Technics’ presentation feels richer/denser. (hifiheaven.net, Upscale Audio)

• Value / “what you get”
  Technics offers top-end driver engineering (coaxial/linear-phase concepts), strong cabinet engineering, and a sound tuned for musicality. If you prefer a more relaxed, musical, well-imaged speaker that’s forgiving of poorer recordings, they’re an excellent option. If your preference is ultra-neutral, surgically detailed sound, there are contenders that trade some musical warmth for extra analytical neutrality. (hifiheaven.net, LB Tech Reviews)

Practical tips (amp, room, placement)

• Use a solid amplifier (able to deliver current into 4 Ω and preferably 50–150 W per channel) because sensitivity is modest. (Technics)

• Give some toe-in to taste: small toe-in tightens focus; more straight-on opens the soundstage. Experiment a few feet from the rear wall to get bass balance. (Witchdoctor)

• If your room is very bright, the Technics’ smoother treble means they’ll be more forgiving than some rivals — helpful for everyday listening. (soundstageaccess.com)

Bottom line

If you want musical, midrange-driven speakers with excellent imaging, authoritative bass and a smooth top end, the Technics SB-G90M2 are among the stronger choices in their class. They’re aimed at listeners who prefer engagement and tonal richness over razor-edge neutrality. If your priorities are ultimate analytical detail or highest sensitivity for use with low-powered amps, audition the Dynaudio, B&W, KEF and Focal alternatives to see which tonal balance you prefer. (Technics, soundstageaccess.com, Speaker Decision)

Would you like a short comparison table that lists sensitivity, impedance, typical price and tonal summary for the Technics and 3 nearby competitors (Dynaudio Evoke 50, B&W 702/703, KEF R7)? I can pull the exact specs and prices and lay them out side-by-side.

 

Then I think you should go ahead. They will probably sound great... but at some point you will be able to upgrade your amp... if you want. 

 

 

Yes, the Cayin A-100T (assuming Ultralinear/KT88 mode) can indeed drive the Technics SB-G90M2 speakers, but with some important caveats:

---

Cayin A-100T Power Output

• The Cayin A-100T delivers approximately 70 W per channel into 8 Ω in standard operation. (HiFi Engine, Polk Audio Forum)

• Based on tube amplifier behavior with lower impedance loads, it may yield closer to 100–140 W into 4 Ω, according to user estimates. (Audiogon Discussion Forum)

---

Technics SB-G90M2 Requirements

• These speakers are 4 Ω nominal impedance, with a sensitivity of 86 dB. (Audiogon Discussion Forum, LB Tech Reviews)

• Manufacturer recommends an amplifier power range of 40–200 W, with 100 W rated and up to 200 W max tolerated. (Technics, Panasonic Help, LB Tech Reviews)

---

Real-World Match?

• According to a discussion on Audiogon:

  “Given the low sensitivity and that the speakers probably drop below 4 Ohms at certain points I think you’d be really pushing it with your amp.” (Audiogon Discussion Forum)

• This suggests that while volume levels may reach comfortable listening, the A-100T will be operating near its limits—especially in dynamic passages or in larger rooms.

---

Conclusion

Yes, the Cayin A-100T is technically suitable for driving the Technics SB-G90M2. Its output likely meets the lower end of the speaker’s recommended range. However, because the SB-G90M2:

• Has modest sensitivity (86 dB)

• Is a challenging 4 Ω load with possible dips

• Benefits from dynamic headroom in demanding passages

You may experience limited headroom, especially at moderate-to-high listening levels or in large, acoustically lively rooms.

---

Recommendations

• If your listening levels are moderate, and you’re in a medium-sized room, the pairing can work well—especially if you value the smooth, musical character of tube amplification.

• But if you frequently listen loud, or your room is large with high ceilings, pairing the SB-G90M2 with a more powerful and more stable solid-state amp (100 W+ into 4 Ω) may be a safer bet.

• Alternatively, consider combining the Cayin with careful placement and room treatment to maximize perceived loudness and bass impact without strain.

---

Would you like help identifying solid-state amps in the 100 W+ into 4 Ω range that complement the tonal signature of the Cayin and suit these speakers?

I knew tube amps perform differently when compared to SS, but I didn’t know there wasn’t any increase in the power output when using the 4 ohms tab.

Haven’t heard these speakers but they look really well-built and seem to have the type of sound I would prefer. Unfortunately, they are big and heavy, and wanted to make sure before committing to this purchase.

More of an issue than efficiency actually: Those are 4 ohm nominal impedance speakers, a bad match for a tube amp. 
 

Options for best performance including ability to go loud unfettered:

1)  Higher power Class a/b SS amp with high current delivery capability.   That will be larger, heavier, consume more power to operate and likely cost more.  You might even go class A which magnifies all of the above to achieve a particular SPL. 

 

2)  Class D amp with similar power capabilities.   Stability down to 2 ohm impedance is desirable (in any case for 4 ohm nominal).  Smaller, lighter and more  energy efficient.    These are all I have used now for the last 10 years or so.

 

Tube amps can be a fun alternative but only with the right speakers.   8 ohm nominal impedance or higher.   Sensitivity then comes into play mainly to determine how loud you can go.  
 

Note that tube amps and Class D amps in general tend to soft clip, which is a desirable feature in general.  

 

 

 

the Cayin will be able to output adequate power but I might be missing out their full potential. 

Exactly.  Plus pushing an amp close to its limits will sacrifice ultimate sound quality on that end as well.  It’s a bit more expensive, but I’d recommend looking at the ProAc D20 as it may share many of the same characteristics while being easier to drive.  Best of luck. 

You need to demo the Technics speaker before making any decision. Japanese branded speakers have(in general) a distinct sound characteristic. A modest tube amp would not be the best match on paper with the Technics loudspeaker.

This was taken from your 2018 thread:

"I moved from a small space to a very large 950 sqft loft with 15 ft ceilings."

This is important info if this is still your space (especially the ceiling height).

 

DeKay

My first nice set of speakers(at least in my opinion) were the Hales Concept Two. I drove those speakers with Audio Research VT-100 amp and Audible Illusions preamp. Never had a problem driving those speakers and enjoying great music.

@mamifero There's a big difference between an amp's ability to simply drive a pair of speakers and its ability to make them sound as good as possible.  It's not about the watts.  It's about the current (i.e.  power supply).  I'm not familiar with your equipment.  However, here's an example of what this means based upon personal experience:

In a critical listening session (i.e.  shopping experience), a pair of truly outstanding Aerial Acoustics 6T (impedance 4 ohms, 3 ohms minimum, low reactance, 90 dB for 2.83 volts at 1 meter on axis) sounded absolutely sublime to my ears when fed by a truly outstanding McIntosh MC275 tube amp (75 Watts X 2 channels or 150 Watts X 1 channel).  Did the Aerial sound good, indeed very good, with a McIntosh MA5200 (100 Watts X 2 channel into 8 ohms)?  Yes.  However, my ears could hear, instantly (i.e.  no more than 3 or 4 seconds), that these speakers needed more current to perform at their best.

 

@mamifero The speakers you have in mind are 86dB and 4 Ohms.

Sometimes its worth considering what this looks like in terms of efficiency rather than sensitivity, since efficiency is stated in Watts rather than Voltage. This is especially important if you have a tube amplifier!

To convert from sensitivity (2.83 Volts/1 meter) to Watts you need to know the impedance of the speaker, which is 4 Ohms. 2.83 Volts is 1 Watt if the load is 8 Ohms (into 8 Ohms sensitivity and efficiency are the same thing), which means into four Ohms its 2 Watts. That's a 3dB difference, which to the ear isn't much but it represents a doubling of amplifier power. Tube amps don't double power when you cut the load impedance in half. 

Another way of looking at that is subtract that 3dB from the sensitivity spec; you arrive at 83dB. 

That is so inefficient that you may have real problems finding a musical sounding amplifier that also has enough power to drive that speaker much past a conversational level. In most rooms this means you'll want something north of 1000 Watts per channel.

If this seems hyperbolic on my part, consider that to double the apparent volume requires an increase of amplifier power by a factor of 10.

@dekay makes a good point! 

Since your amp doesn't double power into 4 Ohms this is a very practical concern. If I were you I'd consider a more efficient speaker as this combination will have the amplifier struggling all the time. If no-one has pointed this out yet, tube amps are less efficient using the 4 Ohm tap and tend to have less bass bandwidth (as well as slightly less power).

IOW I think that speaker with your amp isn't a good idea. 

 

@mamifero - This remains a math problem wrt having enough power to drive that particular speaker to the desired SPL for your room and listening position.

The post by @atmasphere below explains why I used 83dB in my calculations.  To his point, even my second example of a 200 wpc amplifier that doubles into 4 ohms will only drive those speakers to a SPL of about 100dB at 12 feet.  That calculation does not take into effect a larger than typical room, speaker impedance anomalies, or the desire for greater dynamic headroom so, even at 200/400 wpc you my have barely adequate power.

As a result, there is probably no way you will have satisfactory results driving those speakers with your current amplifier.  I don’t disagree with the 1,000 wpc recommended by @atmasphere, assuming he means into 4 ohms.  IOW, an amp delivering around 400 to 500 wpc into 8 ohms and doubling into 4 ohms, should be about optimal.  The Cary 500MB amps in my second system provide 500/1,000 wpc of power, and the SMc Audio monoblocks in my main system provide 650/1,000+ wpc and do an excellent job of driving Aerial LR5 speakers that have the exact same sensitivity and nominal impedance specs as the Technics speakers you are considering, while dipping to an even lower minimum impedance of 3 ohms. 

As to sound quality, IME, amplifiers do sound different from each other so, like any component, you will need to find amplifiers delivering the type of sound you want to hear. However, if you don’t get the power right, your speakers will never reach their optimal sound quality.

It's like dating a girl and you don't like her parents.  They don't like you but she likes you.

Overall not a good situation probably worth avoiding unless this girl is simply awesome because she's willing to put up with you and it's doubtful you'll find someone better.

@mamifero I forgot some things. 

There is a phenomena known as 'thermal compression' in loudspeakers. Its where the voice coil heats up with bursts of power through it. The more it heats up the more compression.

This is why you read about more efficient speakers being more dynamic- with less efficiency (or sensitivity) the bigger this problem is. Vented pole pieces and the like certainly help, but do not solve that problem.

Here is advice I give to anyone who owns a tube amplifier:

If you want the most performance out of your tube amplifier investment, consider a loudspeaker that is 8 Ohms or more and as efficient as you can get (watch out for speakers with dual woofers which might be 4 Ohm in the bass but 8 in the mids and highs, which might simply be rated as 8 Ohms or '8 Ohm compatible'). 

All amplifiers regardless of technology make more distortion into 4 Ohms and speaker cables become far more critical too. Quite literally if you could make the speaker be 8 Ohms or more it would sound smoother and more detailed due to the reduction in distortion from the amp. This is especially true of tube amps. 

 

There is one tube amplifier that was designed specifically to handle low impedance loads: the Music Reference RM-200. You can read reviews of the original and Mk.2 iterations of the amp by Michael Fremer on the Stereophile website, with test bench measurements by John Atkinson. Both men were very impressed with the amp, Fremer declaring the amp his choice for best "reasonably" priced tube power amp. The RM-200 remained in Stereophile’s Recommended Components List for over ten years! Each channel of this stereo amp creates over 100 watts from a single pair of KT-88 tubes, and does so without running the tubes hard (and therefore shortening tube life).

 

An option to consider is to add a real good subwoofer to augment your speakers, with an external active crossover to filter out the very low frequencies from reaching your tube amp. Removing just one octave of bass (20-40Hz, or 25-50Hz, 30-60Hz, 35-70Hz, 40-80Hz, 45-90Hz, 50-100Hz) cuts your power amp requirements in half! Remove two octaves (20-80Hz) and that figure rises to 75%!! But that is true ONLY if you remove those frequencies from the signal reaching the amp powering the speakers.

 

By the way, for anyone wanting a dipole planar-magnetic loudspeaker to use with a tube power amp, consider the Eminent Technology LFT-8b. While it is as low a sensitivity/efficiency design as are the Magnepan speakers (around 84dB), the LFT-8 presents an almost perfectly resistive 8 ohm load to the power amp. And, since it has dual sets of binding posts (one for the planar-magnetic panels, a second for the 8" dynamic woofer in a sealed enclosure, for frequencies up to 170Hz), the speaker can be easily bi-amped, drastically reducing the power requirements of the panels. Those panels themselves present an 11 ohm load to the amp, great for tubes. The ET LFT-8b got a rave review by Steve Guttenberg, who stated in his review that he considered the speaker superior to not only every Magnepan he has heard, but also every electrostatic design. I’m not sure I would go THAT far.

 

I am in agreement with and will now defer to the AI summary provided above which summarizes things very practically,  I would say.

For absolute best results, you want to throw the kitchen sink at those speakers amp-wise.   Class D will help keep things manageable.

 

In similar situation with my big Ohm F5 speakers, I chose Bel Canto ref1000m (500w/ch 8 ohm, doubles to 4 ohm) as the "kitchen sink" I threw at them about a dozen or so years back  (search my old posts for more info).

This year I moved to latest Class D technology with 200w/ch Class D Audio GanFET amp.   Beefy enough and better performance overall, in particular with the high end and overall detail and dynamics.

Cheers and good luck!  

 

Hey OP

as others have suggested, try to go to SS based amps, specifically GAN based amplifiers. they sound very analog, similar to tubes. also suggest you use a tube-based preamp to power up the Gan based power amps

my recommendations that you look into are

1) AGD

2) Laiv mono

3) Orchard Audio

4) ClassD Audio amp

the last one is the name of the company

this link:  2 Channel Stereo GaN Amps Archives - Class D Audio 

they seem to have good reviews for a more inexpensive Price

 

see if they have a 1-month trial

 

i suggest you put your gear together using your existing amp and see if there is something missing or will you have a "wow" moment. then decide from there

Thank you all for the information, it's very helpful.

Indeed, these Technicns speakers seemed promising, but they might be too demanding for a 75 Watt per channel tube amplifier. Down the road, I will get a solid state or one of those nice Technics integrated (which are not class D, they have their own thing -pretty neat). But for now, I'll look into 89-90 dB efficiency range.

My current speakers are 4 ohm, 90 dB efficient and this Cayin Tube amplifier drives them pretty well, however, I can notice how the sound profile changes when connected to the 4 or 8 ohm tabs, one is a little softer, detailed and linear, while the other tab gives you more dynamics and a V curve sound.

@mamifero, Heat Dissipation and Power Compression in Loudspeakers see here. Sensitivity vs. Efficiency: See here page one section C. For in the what it's worth category, power compression in tweeters can start with as little as 10 watts of input.

Just because a loudspeaker will work better with a big solid state amplifier doesn't mean it won't work very well with your moderate power tube amp.  I am not familiar with either the loudspeaker you are considering or your current amplifier.  The Technics isn't an easy load, but it's also not difficult load.  It's honestly rated at 4 ohms.  With 4 KT88s per channel your amp should have enough to drive them.  Depending on how loud you listen, your room and your musical taste you could find the Technics/Cayin combo absolutely fabulous.

BTW, your conclusion to look at loudspeakers in the 89-90 dB efficiency range hints that you haven't grasped what people are telling you about matching loudspeakers to amplifiers.

@onhwy61 The speakers in question are only 83dB 1 Watt/1 meter. Sensitivity-wise this works out to 86dB, but we're talking about a tube amp here and they don't double power as impedance is halved. Instead they cut power in half as impedance is doubled if they are acting as a Voltage source. 

So this is simply impractical and won't work out as you forecast above. 

@mamifero If you like your amp, I'd look for a speaker that is 8 Ohms or more. Your current speakers are 4 Ohms so their actual efficiency is 87dB. Your amp is working hard all the time with that speaker- they are not showing it in its best light. By simply moving to an 8 Ohm speaker that is 90dB your amp will need only make half the power it does now for a given sound pressure level. That will reduce its distortion and it will run cooler as the output section will be more efficient. 

@atmasphere, you basically restated what you said earlier in this thread and it's a very sound argument.  I just don't think you are allowing for individual, subjective taste.  We've both participated in this forum for a long time.  One of the things that has been revealed to me is that not everyone has the same goal(s) in assembling/setting up their systems.  It's not even an accuracy vs. musicality schism in that there's not a solid agreement as to what those terms mean.  (There's actually a lengthy thread trying to define "what if high end".  The responses are quite varied.)  Instead our music reproduction systems are more of a reflection/projection of ourselves as audiophiles.  Just look at the variety of systems people have.  As such our systems can be technically imperfect or non-optimal, yet the listener still is very happy with the sound.  If some people want to pair Magnepans with single ended triode amps, my response is go for it and tell us how it sounds.  You want to place big Wilsons in your 12' x 12' room?  It might not be something I would do, but go ahead an give it a shot.  So while I have an opinion about matching the Technics with the Cayin, I and nobody else in this thread can truly predict whether the the OP won't like the combination.

Let's not get all boring and start agreeing on everything.

@onhwy61 I agree, however for me its really about how it can sound even better and thus be enjoyed more too. Put another way its about getting the most out of your hifi investment. 

 

Review Technics SB-G90 floorstanding speaker 

''So you have been able to read that this Technics is a big heavy, 3-way bass reflex speaker. So far so good. The nominal impedance is 4 Ohms and the continuous load 100 watts. 200 watts peak. That’s more than enough for many a living room. It takes about 40 watts to get it going. We estimate that a tube won’t go very well, but who knows with a heavier 300B it might work, considering the efficiency is still about 88 dB. That’s not super high, but it’s not low either.'' see review here
