No The Bench xover is the one I have, I just need the time to go into the Speakers and complete the power supply for the xover. Maybe too many things at once? I want to set up a bi-amp SS system and a Tube based system and compare . There is a meeting of the Audio club here in 2 weeks. I want to try to exhibit the 4's. I want to place them in the ALL TIME BEST BANG FOR THE BUCK division. Love those big guys! Hope I can get them ready; it's a long shot but if not, then next time. I started going to meeting's after a long layover, comparing equipment gets old after awhile. And I don't care for that elevator jazz everyone seems to crave. I would rather listen to Johnny Rotten. Or Sid Viscious. Something with SOUL. COJONES. J.R.
