ESS AMT4: Worth repairing?

Eno,
ESS is still in business & probably has a service center or can sell you the driver. My brother replaced his 10" woofers & with ESS being local for us in the sacramento area it wasnt a problem....try www.essspeakers.com or 916-362-4102.
Hope this helps you out

I have a pair of ESS AMT 1 Towers that I just had rebuilt. I found a speaker builder on the Madisound website that was willing to do the work. He designed and built new crossovers and replaced the old 10" woofer with a ScanSpeak 8" mid-woofer. I also use a Velodyne HGS 15 sub, so in effect it's like a three way system. I've heard many of the top brands of speakers ranging from $5000 to $35000. I wouldn't trade my retro-fit ESS speakers for any of them. If you can find someone to do the work, it will cost you about $500 for the parts, plus the labor.
If you just want to replace the original 10" woofers, you can get them from ESS, as mentioned above. I believe that they are about $49 each, and they will have heavier magnets than the originals. I actually purchased a pair a few years ago, before I decided to try to have the system rebuilt.

You have probably repaired your AMT 4's by now.You have to take into consideration that the AMT 4's are rare to find, and worth every penny you can muster to have them repaired. There are very few of them. They are almost as good as the ESS AMT 3 Rock Monitors. The only difference being the AMT 3's uses 2 10" woofers. In spite of the new technology of everything getting smaller,the AMT 4's still sound great;whether playing analogue,or digitized sources. My synopsis: Look in the yellow pages of your city to find more sources. Don't give up on these rare puppies.
