Maybe you have sold these already, but I can answer any questions about them. I do NOT know what they are worth or what others would pay, but they are tremendous-sounding speakers: airy, spacious, like huge electrostatic headphones. And the stereo-everywhere technology (horizontal radiation pattern where the l-r balance is consistent with listening position) really works rather well.The EQ unit was rather complex but you can do a crude duplication simply by turning up bass and treble controls significantly, as you suspect. Or get an inexpensive 10-band octave EQ and do the butterfly turnup and then experiment by ear. You will want to experiment with notching 2k and 4k a little bit with the octave EQ.
