Wife and I are designing cabinetry to go along the wall in our family room. Imagine a 24" deep base cabinet with bookshelves on the wall above. The base cabinet is going to hold the audio equipment and the TV will sit on the countertop. The issue is placement of the M22Ti's we use as our front speakers. She of course would like to put them on a shelf with their back against the wall (Actually she would like to put them inside the base cabinet with grille clothe in the cabinet door but I think I have defeated that proposal). I would leave them on their stands in front of the new cabinet or on the countertop next to the TV, in front of bookshelves, which would put the back of the speakers about 12-15" out from the wall.

It seems to me the M22Ti can't really sit within an inch or two of a wall on a bookshelf because of the rear porting, but what do I know? So can somebody answer this : how close to a wall can you put a rear ported speaker without affecting the quality of the sound ?
