Hi Ian/All
I hope you don't mind if I piggyback my question on this thread since it touches on Ian's replies.
I am running a L100S whose XO duanage modified for me. It has a crossover where the woofer has been separated to make it bi-ampable. It has dual binding posts, with bridging bars to run it in normal mode. It has L-pads added to the mid/tweet.
I am currently running it with an Adcom 555/500 GTP pre in the normal fashion. On it's way is an Adcom 535 which I will dedicate to the mid/tweet.
The reason for this approach is because I have heard opinions that the adcom 535 is the best sounding of all the Adcoms, and I wanted to offer that to the top end of the speakers, and retain the power of a big- amp system,.
My question is, should I look to use and active XO as a pre-amp filter to reduce the load/frequency's the amps need to reproduce, before getting to the passive XO?
Should I use the active XO to let the 555 power the woofer directly?
I have no particular desire to use an active XO, other than acknowledge that it waste's alot of the amps power not to do so.
I get the drift of the posts here that an active XO is not a good solution.
EDIT: I'm also curious if the active XO could address phase issues between the Woofer/mid at the XO point.
