I recently purchased a CSi25 center channel for my home theater set up. Aesthetically speaking the ideal placement for the speaker is on the shelf under my tv in an entertainment center. It is enclosed on 4 sides but open in the back and front (obviously). I've read some comments about not placing rear ported speakers in an enclosed cabinet or shelf. Although most of the comments (that I've seen) don't really explain why. Is the back of the shelf being open enough breathing room? Or should I try to explain to my wife why we need a big hulking speaker on top of the entertainment center?
