Just reinforceing "Msontang" with the CDM9NT is deffinately worth looking into. You already know that you will need a sub to complete the set up and always consider others, but I would match it with a B&W. I use Krell KAV 250a/3 and DS-6 B&W surrounds with amazing results so I have to stress good amplification to the surrounds, but you won't be sorry with any of the B&W's. I added front left/right/center ASW800 subs for the slam you are seeking. I used the center to pair with my matrix HTM for full range center and I even use the L/R for music with my 801III's with excellent blend and slam. I use 2 Bag End infrasub 18's for my LFE in the rear and what a foundation shaker. I hope I gave you something to consider and I think you are on the right path. Good luck!
B W 804 for Home Theater
Lets talk about B&W for a moment. I have heard rave reviews about their Nautilus speakers and am curious about their suitability for home theater. I have looked at the 804s and 805s as well as the matching center channel. Does anyone else use this combination? Would the 804s/805s be acceptable for left/right front if paired with a proper sub? I am concerned that the small drivers on these speakers might not be up to delivering the proper slam that is needed for home theater. My home theater room is small and I am looking to purchase a matched set of speakers that will stand the test of time. Thanks.
