Anyone care to share their opinion on this:

I am getting ready to take the plunge for some new speakers and HT receiver (Yam 2400, Denon 3803).

I am leaning towards trying the M22ti, QS8, VP150 route, but I have an issue with the M22's that I was hoping to get some input on.

My fronts (and center) have to be housed in the top three sections of a built in cabinet. Each compartment is 25"x25"x31" (HxWxD). I am concerned about placing the speakers in there (but due to the WAF, I do not have an option of using floors, or mounting them on the walls).

I know that these are ported speakers, would lining the interior of the cabinet with polyfill or some other material help or hurt?

Is there anything I can do to reduce the effects of having to place them in these cabinets?

Those are pretty big openings. I would think that you would be fine as is, but I'm not absolutely certain.

Bogie, it's generally suggested that at least 3" of breathing space for rear ports be allowed. Because of the size of the compartments, as Ken noted, you should have no problem with that factor, especially since you should have the front of the M22s protruding a little bit, say 1", from the cabinet to minimize diffraction effects. Also, the M22s should be tilted slightly downward so that the tweeters point at your ear level at your listening position. So, not ideal, but it works.
