Mixing b&w 703 with cdm 9nt and cdm cnt

I'm suspecting you are going to run the NTs as fronts and the 700s as rears in a multi ch arrangement?

The NT sereies across the front where I believe it matters more so, should be fine enough a setup sonically. rears really are lesser a concern.... especially if a HT receiever is being used, as it has tone controls usually.

I'd suspect very little adjustments would be needed for the 700s if that's the case.

I use a cdm nt-center in my system. Originally I had cdm 1 se fronts and rears-that sounded great-I upgraded the fronts to merlin tsm's which sounded even better.I listening mostly to 2 channel-but the family likes the home theater sound with movies and this system delivers-I use a velodyne for lows-I do not think mixing what you have would be a problem.
