The Magnepan edition of the ICBM would allow you to use a higher crossover point (assuming your current surround processor doesn't already allow that), which could help the speakers blend better with the sub. Unfortunately, the ICBM (both standard and Magnepan edition) has been discontinued. It couldn't hurt to call Outlaw and see if they still have a spare Magnepan edition hanging around the warehouse, but I doubt they still have any.
