This may be a totally subjective question, but if there are any objective facts, this should be the forum to find out!

I'm going to have a small, (13ft wide x 16ft long x 8ft high) room in my new house for a home theater. It will have a door, so it can be totally sealed. So that's only about 1700 cubic feet.

I plan on using a nice Infinite Baffle subwoofer to handle the 80hz and below sound.

So my question is this: Since the HTM-200s can go down to 80hz, is there any advantage to getting CBM-170s or CMT-340s? Right now, I'm under the assumption that the sound between 80hz-20khz is the same or close to it on all three of these.
