Do old Acoustats compete with new 'stats or dynamics


I listened to a pair of Acoustat X's driven by their Servo Tube Amp, Audio Research SP-3A-1 preamp, Micro Seiki table with totl Signet cart and it was a captivating presentation that started me on the road of High End Audio. Will the newer Acoustat models through the Spectra series still compete or hold their own against newer speaker designs? I am talking about soundstaging, imaging precision, frequency balance and overall impact.

Hi Pix4work

I have custom build Acoustat Model 3's with granite bases. See my virtual system. Their only drawback is when you stand up as they are not tall.

The simpler build Model 3's outperformed my more complex Acoustat Spectra 33's. As good as the Model 3 sound, my Quad 57's make the Acoustat sound..... artificial. Everything sounds like - at the microphone - with the 57's. They are Wayne Piquet rebuilds.

I have just posted on my virtual system about my DM70c - B&W Electrostatics revival. They are special. An integrated woofer cabinet that blends well with the ESL Panel.  
  
Go for the Acoustat  - if they are in good condition.

***************************

Mijostyn -Right now I have 2+2s and an ornate subwoofer system crossed over at 125 Hz.

That is a very high crossover point ?
I only need to cross the subs I use with the Quad 57's at 60 hz.

I have a pair of Model 2s that came with the interfaces but I modified them to work with a pair of the Acoustat servo amps I picked up. I also modified the panels to achieve greater dispersion. The sound fine on their own, but subs do improve things. I biamp crossed over at 100 Hz for low pass and high pass using 4 woofers.

I also have Quad ESL 57s and Roger Modjeski's ESLs with his direct drive amp. I can say the Acoustats hold their own against both of these speakers. As for more modern ESLs, the best I have heard is Sanders Sound which has an integrated bass driver. You don't get the dispersion of a SoundLab, but I could never see what the big deal was about SoundLabs anyway. Nice speakers, but I'll stick with what I have.

@ct0517 interesting you cross the Quads over at 60 Hz. I cross mine over at 100 Hz to avoid the intentional bump a 90 Hz that Walker designed into the speaker.

Hi Clio we have discussed this ..2 years ago ? But I don’t mind rehashing.
Walker’s design assumed his speaker (singular) ONE would be set up like this in small British rooms.

He never thought they would be set up like this.

They become very linear and room filling. Get those dipoles away from the room boundaries for best bass. The Room is the boss. "All" Gear are just Slaves to it.

fwiw
All Soundlabs I have heard (2) and in pictures were in rooms much to small for them (JMO), so I cannot comment on their potential.

Cheers

Thank you for your input!

Tweak1, I share your thoughts about Maggies; I appreciate what they can do, and while I have listened to the newer 1.7i, it still does not tick enough of the audio boxes to keep me listening for hours. I have yet to hear the Emerald Physics, they are an interesting design as I like OB-type speakers. Intriquing that they have 'stat-like qualities.

Mijostyn, I hear you on the Sound Labs design; their dispersal pattern seems to be what most 'stat lovers crave the most, and the 845's would be amazing. I really appreciate your heads-up on the loose panels as I have toyed with assembling an Acoustat pair from parts, as well.
ct0517, It would be a lot of fun to listen to your 3's vs. the rebuilt 57's, as Wayne's builds are said to be as good as Quads get, and produce bonafide bass. I have wanted to listen to a good pair for years...Those B&W electrostats are fascinating, I would welcome an opportunity to hear them sometime; who would have guessed B&W ever built 'stats?
clio09, Congrats to you for figuring out a way to use the Servo amp with your Model 2's; it's hard to beat the qualities of good tube amps. If you could share about how you achieved better dispersion on your panels that would be helpful, as that is the area I have had questions about. Also, I guess it should be no surprise that Roger Modjeski designed ESL's, as well as top drawer amplifiers; an amazing guy and he is missed by many. Sanders Sound electrostats are another speaker I would like to compare Acoustats with, however, they seem to be fairly rare in number.

All things considered, it seems as if Acoustats still have some life left in them, and the fact that the high voltage interfaces can be rebuilt is very encouraging. I have read that the 1+1 and 2+2 models have the best imaging, which, along with speed, is what I am looking for the most.
Thank you for all of your replies so far!

God only knows. 
Oh dang, now this thread will have to be taken down too.
