Thanks Gonk. That's about what I figured too. I may give my DVD player's DD decoder a try to see if it is decent. That way, I could go from DVD, to ICBM, then to 1050 via 5.1 inputs with all speaks set to large thereby being able to set different crossover points via the ICBM.
Right now, I change the x-over point depending on 2-ch music or DD/DTS use since my mains can reach around 57+/-, my CC 75+/-, while rears are around 90+/-. (60hz for music and 80hz for movies gets the best results for me right now)
