Another question - Regarding the M2's planned to be installed in a TV cabinet.

Can anyone comment on the sound quality of the standard bookshelf design in that type of installation. It would be easier and provide some future flexibility if I used the regular bookshelf design instead of the in wall I was considering for that location.

I know the bookshelf speakers are supposed to sound best on stands a few feet in front of a wall but will they be really compromised much if they are placed on a shelf ?
