I'm in the midst of designing an in-wall entertainment unit where I would ideally like to put my Paradigm bookshelf speakers (mini monitors) and center channel (CC-370) in the cabinet. Keeping in mind how important speaker placement is, I'm wondering if this presents any problems with a rear ported speaker as both the minis and the cc-370 are. For example, should there be a certain amount of space behind the speaker or on the top and sides so as not to affect the speakers sonic accuracy? If this is a bad idea altogether, should I perhaps invest in speakers that are ported at the front? Any comments would be appreciated. Cheers.
