wel i have alot of width and height its the depth thats the concern as i dont want it stick to far out form the tv.http://www.musicdirect.com/p-210628-dynaudio-dm-center-speaker.aspx
for the size of this thing, the performance is really good. And its priced pretty low.
however the best center channel will be the one that matches the current left/right speakers that you own. If you're buying L/Rs also, the DM2/6 is easy to power I use them as surrounds, the DM2/7s have better bass.
