[QUOTE="ludo, post: 50039, member: 691"] Passive xovers and low freq are crazy to my cheapskate mind. One can do it on 12V. Things work a bit less well as the voltage gets lower, but I don't think there's going to be any real problem with headroom yet. (It is the part of the spectrum where one has the big excursions but a CD player can only swing so much voltage and an amp can only take so much before it clips.) One can leave a bit of space for different cap values/sizes. Many nicer opamps can also just drop in the same sockets. Gotto run. Will ponder it on the way. [/QUOTE]
