Prior to obtaining the 990, I was running a B&K Ref 30 prepro with an ICBM (Magnepan version) between the prepro and power amps. Front left and right speakers are Magnepan 1.5s (pretty close to full range) and the center channel is the Magnepan MGCC-1. Never mind the other speakers - this question is complicated enough!

Use of the ICBM was necessary due to the Ref 30's very limited bass management and the limits of the Magnepan MGCC-1 center channel speaker. The MGCC1 speaker only goes down to about 160 Hz and most subs aren't designed to go that high. The Magnepan version of the ICBM was designed to allow the bass below 160 Hz to be routed to large front speakers. This is done by switching on the ICBM L/R Recombine switch.

I'm trying to figure out if this setup can be accomodated with the 990 without the ICBM. I'd like to have as few components (and cables!) as possible in the signal path. I can set the 990's center channel crossover frequency to 160Hz, but I think this just sends the bass below 160Hz to the subwoofer.

Has anyone on this forum encountered this issue in their system? Any ideas if and/or how it can be setup without the ICBM?

Thanks,
