Ok, I think i've answered my own question. The analog bass management is immaterial in this regard as it is only 5.1, so i can leave it off and use the ICBM as I always did. The High pass crossover and output level control within the 950 should do what i need, so i will not use the ICBM with these speakers.
Of course it is all moot now, but why did they make the ICBM 6.2? - Love the .2 though !
