The ICBM will eliminate all the "double bass" problems w/ the 950, right?

I've recently upgraded my speakers to full range (VMPS RM40s) and I get a REALLY annoying double bass when I do any 2 channel listening. I have to turn off my subs (either in the processor or the power switches) and I'd like a better solution.

Seems like the ICBM will do the trick?

Also, how do you set-up the 950 to work w/ the ICBM? Set all speakers to large and sub to off?
Does this have any drawbacks? Will any signal get discarded?

thanks
Jon
