Thanks zoomer,
I have been considering going with a active xover system but I still cant decide on the unit I need to do the job. Then once I started thinking about why the quart xovers had the bi-amp feature it all faded out LOL. Right now I'm using 2 old PPI AM2150s one for the tweets and one for the mids and I think it sounds great but I also have a AM2300 that I could use for the same combined power and just run it non-bridged to the xovers and I just wondered if there would be any difference in sound? God I got to stop thinkin
