Hi Eric:
I am assuming you are planning on connecting all the speakers in the room to the same source which means a rather large room or overkill in a small room. My suggestion would be looking at our AMP200 for your tower speakers, our MX1260 (12 channel amp) for your in-ceiling and in-wall speakers and then a SMP250 Subwoofer Amplifier for powering the Subs. I would suggest four IW10S wired series parallel so the sub amp would see a 4 ohm load (versus three wired in parllel). Note the AMP200 (or AMP300) would be plenty for your Tower speakers and the MX1260 would alleviate worrying about impedance matching since you would have 12 discrete channels or six stereo zones with a choice of two universal buss sources or direct input at each channel. Please contact me directly for further assistance and clarification. We would love to take care of your other speaker needs and wiring if you have not made that decision. I can even furnish you with a wiring diagram if needed. My email address is [email protected].
