Who know what I did yesterday much less back then. at the time I hadn't bought these other amps and needed one for the sub???I don't remember..Still remmeber it being the loudest and bassiest of anyting I tried up to that point
when I got 2 identical amps and used a XO with passive bi amp capable I played with the which way to go on the bi amping. I think I may have heard a difference but it was so slight if I did.... I went with Rolf's thread and left 1 amp on each speaker instead of 1 amp for bass and 1 for the rest, I liked the logic of thread when I read it.
I must admit a lot of the nuances are wasted on me.
"I know what I like but I can't express it well. I can tell in just a few moments though if that is the sound I like" ...something like that
