I have a chance to get a pair or ESS AMT towers that are beat up and have mismatched replacement woofer.s I currently own ESS AMT 1d's that are in much better shape. I have heard people comment that the ESS AMT tower speakers can be modded to sound much better by upgrading the woofers and adding a mid-range with the necessary changes made to the cross overs. The ESS AMT 1d's I would probably leave as is due to lack of conventional wisdom on successful mods. . If I can pick up the ESS towers for $80 I would sell the ESS AMT 1d's. The guy had the towers in his drive way and they sounded pretty good. A google search turned up a modded tower that looked very sharp. Walnut veneer on all 4 sides with no grills and the top enclosure was cut off to reveal the AMT tweets. Any one mod ESS AMT's? The mod is supposed to address short comings in the mid-range.
