Bi-Wire works best if the speaker has the X-over sections separated (hi-pass / low-pass). Actually, just separating the X-O improves most speaker's sound. Have done this on DCM TimeWindows, NHT Super Zeros (had to relocate the X-O outside the cab). In both cases, restructuring the X-O made the speakes sound better; wider soundstage, better imaging, tighter bass, clearer highs. Going to bi-wire improved the sound again, but not as dramatically as the X-O work. OTOH, w/ better designs built w/ sep. X-O boards, going from single to bi-wire, the change in sound is not as noticable. One idea that doesn't seem to work (at least not for me) is to use diff. type cable for the lows and highs (ie: 10 ga monster for the lows and DH Silver for the highs). I've tried it sev. times and have yet to find a combo that sounded as good as matched bi-wire runs.
