Hi Cadboy! thanks for the quick reply.

I am running 5.1 but my AVM 20 can be used for 7.1 as well, just don't have the space for the two other speakers. The LFM 2 has a crossover-out bypass which I have set to the bypass mode because the AVM has a very flexible bass management system.

I will experiment with the unit but I believe this sub will really make these B&W's sound even better than they sound now.

all the best and thanks once again!

happy holidays from Dave in Buffalo!
