ATC, the big boys

If you talk w/ Billy Woodman, the prez and chief engineer for ATC, he'll tell you that in most cases he'll recommend that you DO NOT go with the 200's or 300's for most homes. Write a letter to ATC telling them the dimensions of your room and they'll give you the speaker size. ALL of their speakers, from top to bottom have the same drivers. You need to buy the pair that matches the volume that you're trying to fill.

Billy also mentioned to me that they are working on adding a "size chart" to match a range of room volumes with speaker sizes. For example, if you have <2000 cubic feet, You'll probably be told the 20's or 50's. 2000-5000 100's. 4000-10000 cubic feet Active150's. etc...

ALL of the speakers sound exactly alike, but putting 150's into a 2000 cubic foot room would make the bass sound so boomy and overenergize the room. Furthermore, the room isn't big enough to get them far enough apart to properly image. 100's for example need 9' of space between them. 20's into a 6000 cf room won't have the dynamic range that you want.

Hope this helps. The beauty of ATC is they won't sell you more to make more money. They only sell you what is right for you.... www.atc.gb.net

I've been thinking and my brain froze... If you want the best of the best from ATC, you need to buy the SCM70 ASL's. It is the Ultimate and only reference for folks with obscene amounts of cash. They have to match some 40 pairs of MOSFETS exactly. This alone takes like 4 days of labor! The 70's are fully discreet ClassA amps. Same drivers, but the amps are where the more money is going. You will get the single best sound from the 70's. They're very contemporary looking, but you can choose from like 4000 different coverings.

The bass driver is a 9", same as the 50's, but the amazing fully discrete amps and silver wound voice coils raises the price from about $14,000 for a pair of Active50's to about $24,000 for a pair of Active70's. The sound of the 70's is the best sound that you can get. Even at around $27,000 for a pair of 150's, the Active70's are the best sound that you can buy. I'm also not exactly sure if they still make the 70's as they are so labor intensive and time consuming that it's a complete pain as I understand.

I visited the link you provided but found most of the site under construction. Is there a place with good images of the various speaker systems?

You're right. Their new site is still being built. The just switched over a couple weeks ago. Here's their old site, which is not as nicely done, but has a TON more info in it, but you have to dig for it.
