chess,
the sub I have came with my HTIB. Not much in the way of settings. It is part of a JBL CinePropack 600. 5 satellites, and a 8" sub. A 5 channel receiver, plus a 5 disc DVD player. the system has served us well for almost 3 years. The M60's were the first step in upgrading our main system. I am planning on a new receiver, a combo DVD Audio/SACD player, a new sub( maybe HSU) plus the VP 150 and the QS8's.
the Sub only has the LFE input, and no gain or crossover settngs. the settings I have them at now are through the receiver. I have the sub set to -4db. If I need more thump when watching a movie I just set it to 0 or +1db, and it blends well with the rest of my system. thanks for the imput
