Your thoughts about ATC loudspeakers


I’m interested in the ATC SCM-40 from their HiFi series and would like to hear from people who have owned or spent a lot of time with ATC speakers. This is a fairly new model and may be a bit of a departure from their classic sound.

At the show in Newport last weekend, I was quite taken by these speakers. I went back the next day and heard the same things that I liked about them, but a couple of red flags also went up:

Microdynamics – not sure these speakers do them well and microdynamics are critical to communicating inflection and nuance and to making music sound alive

Imaging, specifically wrt depth. Nothing much outside of the plane of the speakers, so recording venue info is not there and even instrument and vocal body may suffer a bit.

Were these shortcomings of setup or associated gear, or is this what ATC does?

Quested Speaker is another one which is underrated IMHO......

I find them Far more musical, easier to drive and far less fatiguing than the ATC. They cost much less.

ATC Residential and Studio Speakers are the same, except the consumer level stuff is boxed with veneer and such to make them look pretty. Open the Studio and Residential system and you will find the same driver and crossovers.

ATC are no doubt up with the best but i think Quested is far easier to listen too, just as transparent as ATC.

The H108 are used by Hans Zimmer, these units can be driven by Tube Amplification with only 20 watts on hand. The crossover are lighter and the speakers generally to me anyways feels more like Music you can connect too.

Quested has been around for years, Hans Zimmer, Michael Bay, Trever Horn are but a few who have stuck by Quested for years and with good reasons.

Fatige is the word that comes to me every time Iv listen to ATC Speakers. If you are using your Audio room for mix and mastering than both ATC or Quested Speakers will work. However for Music so far nothing has pleased me enough than Quested out of the 3 iv tried many times and that's: Quested, ATC, PMC.



Audio Doctor, I understand your a Dealer and thus your comments on this forum is always biased towards products you guys carry. This is evident on the DAC threads as well. You do realise pushing your products on the forum does come across unethical.

I speak from personal experience by owning all 3 speakers in the past 20 years in this hobby. I an not a dealer of either of the companies.

My comments on the composer using these speaker is just an indication that they have stuck by the company for a long time. ATC is used by many studios and composers as well. It could mean something or nothing either way. I am not a Audio Distributor or a Dealer. So I am not biased to any given manufacture.
Quested Used Volt Midrange as I understand it and so does PMC.

The Model is available on the VOLT UK Website.
Quested to me sounds less fatiguing, again guys use your own ears. We share information on this thread and opinions.  Nothing negative in my comments about ATC or PMC. If you are planning to listen to music instead of using your room for Mixing or Tracking the Quested may prove to be more preferable for long term listening session.
BTW: check out the comments on gearslutz when producers, composers are comparing ATC to Quested and PMC. Similar opinions are being shared on their as well.
Go over to Gearslut every experience and opinion iv come to with my own conclusion is shared by many composers and producers. I have no incentive to defend either company. Now we have 2 ATC Dealers on this thread. Things are becomming interesting.

Take my opinion as a grain of salt......I'm not involved in distribution or dealership business.
I did not claim any speaker is the best or superior your twisting my original thread just because I’m simply telling you its unethical for a Distributor/Dealer to constantly pound the forums at pushing products.

I already made you aware about this on the DAC Thread forum which you constantly rant on about with sales talk. Stop pushing your products on the forum. Their is something called general advertising you can take part in.

I simply gave my opinion that the ATC speakers iv had were fatiguing and required large amplification mainly Solid State however Quested were easier to drive and less Fatiguing. Neither is superior and each speaker will work well within its purpose installs.

Again your post are simply advertising spin off.

Out of ATC, PMC and Quested. The Quested Passive Speakers were the only ones which could be driven with Tube Amplifiers less then 50 watts. Every other passive monitor iv used required high powered Solid State gear. ATC are Power Hungry Speakers due to the crossover they use.

No one is Attacking PMC or ATC neither any claims are being made one is superior than the other. Please read my post carefully before you jump to assumption and marketing hype.

I prefer Tube Electronics and I found Quested are by far the easiest speakers to drive out of all 3.

Again I must stress, I am not a Seller/dealer so i have no intention to sell anything to readers on forums. No motive to push perticuler products. I have experience with all 3 and you don’t!
Audio Doctor,

Please Stop Marketing your products on Agon. If you need to use the advertising section please do but bashing on the forum and pushing products is very unethical as a salesman. How many times do i need to keep telling you??

Its obvious your always bias to the products your selling yet you have no experience with Quested Speakers and still feel the need to comment on them.

I take part on gearsluts and iv read thousands of threads a lot when comparison have been made with PMC, Quested, ATC Speakers.

No speaker is superior, each one works well within its parameters and purpsoe of install. Every user has diffrent opinions and preference.

I find them Over Analytical, which is an excellent character for Studio requirements not sure if everyone would appreciate this whilst listening to music. In anycase, I said before ATC are excellent, So are PMC.

Out of all 3 Quested was something i preferred, simply becuase it worked better for me, it was easy to drive and I experience no forms of fatiqge.

Other users on the forum may disagree that’s perfectly fine but please do not twist words by claiming one is superior than the other.
Yes this is what I felt about both speakers, overall on the matters of bass I still liked the Quested, for mids I still like the Quested again. The Biggest Point was Quested worked with Tube Amplifiers and the mids was more holographic and lucid with Tubes amps in the mix.

I can easily swap out different Amps, With the ATC I was stuck with Solid States only. So Pick your poison as no speaker is perfect!

ATC transmission line bass seemed slightly! lacking to me, it was tighter/faster but lacking to some sense it would NOT fill in the bottom end properly on certain musical genres only.

The Quested by comparison just felt a little more satisfying, but did not have that last ounce of definition that the ATC produced.

The Quested would fill in the bottom end better and give a better low level energy at the cost of losing some definition. This overall for me worked out better as I don’t sit around listening to audiophile recordings.

I would give the ATC mids a slight nod to details as comparison to Quested or PMC. I wish I could have tried the Tubes on ATC this may have slightly change its character but none of my tube amps worked well.

When it came to playing Music and using Tubes amplification from OTL Amplifiers to Push and Pull. The Quested just worked with everything very well.

Well anyway, If your a Solid State guys than ATC is an excellent speaker as long as you have large amplifiers to sufficiently drive them. They are truly excellent speakers but require very good amplification. Iv never tried Class A Solid State amps on ATC.....Wish I did.

I was once a Solid State guy, moved to SET, Push & Pull than OTL. Once i went OTL I never looked back at other Tube Amplification simply because I found OTL just did everything right. Their are issues running OTL and one of the major aspect was they can not run low Impedance speakers very well. So your stuck with a limited type of speakers.

Their are always trade-offs in this hobby, we just have to understand which area we can easily compromise as acceptability.

I never consider any speaker as THE BEST.....this hobby all comes down to personal taste and listening preference.

Living with a easy to drive speaker just gives one more flexibility to move around amplifiers time to time. At the end of the day we all get that upgrade itch at sometime. Their is no such thing as Destination Audio. Its a constant evolving process. Something I learnt painfully.

It is not about Surgical transparency for me anymore. I want to  be emotionally connected to the music. The emotions that stir within us during the listening session is the magical experience I'm after.
