I just picked up a pair of Accoustat 2+2's at a great price, and would like to modify them. Does anyone know what people change on these speakers to make them sound better? Wiring changes? What brand? Frame stiffening/reshaping? MK interface changes? The obvious changes I see are: Removing the grill cloth, Upgrading the low voltage caps on the high-pass filter, eliminating the fuses, upgrading the binding posts (biwire?) and low-voltage wiring, and possibly eliminating the 1 ohm resistor (I will be using a high-current solid-state amp). BTW, I test-drove the speakers using my Musical Concepts modified DH500 and TWO pairs of Straightwire maestro speaker cable. They sounded pretty good. And if there are any cable skeptics here, there was no doubt that one pair of maestro did not sound as good (less bass/detail/texture), and FMS grey 1, and Vectuer CV50 were not even in the running. Associated equipment for the session were a Phillips CD-80, ModSquad deluxe line drive, and maestro interconnects. I'm interested in mods to improve bass in these speakers. It was a little flabby. Should I get out a heat gun and tighten up the diaphram? Would making the frames stronger, more rigid, heavier, and spiked help? How about adding "wings" to reduce back-wave cancellation? So, if you have any first-hand, second-hand, or non Stereophile/Absolute Sound/Audio Amatuer/Speaker Builder references, I'd love to know. Thanks, Mark Kaepplein mhk@ileaf.com (617-290-0710)

It had a cutesy name, and wasn't too expensive as I recall. I heard reports that it was a substantial improvement. You may want to contact them and see if yours are pre-upgrade. Hope this helps, jimbo
