"The front speakers should be placed on the center line of the screen.
Clearly, with an RPTV or Direct View this is not possible...the next ideal
location is to have the center above the screen.
The problem with mounting free standing speakers in a wall, or in a
cabinet, is as a result of "boundary effects". Free standing speakers are
designed to provide a reasonably flat response curve when situated at the
manufacturer's recommended distance from walls. Speakers designed for
in-wall, or in cabinet installation have been designed to compensate for
boundary effects. While a free standing speaker would have problems
mounted in a wall, an in-wall speaker would have similar problems being
located in a free standing space.
Now, having said that, you can install free standing speakers in a
cabinet. However, the interior of the cabinet must be completely filled
with sound absorbing materials and the face of the cabinet must also be
treated as well.
The negative comments about in-wall speakers are somewhat justified.
Justified only to the extent these speakers (as a genre) were designed and
developed to meet two criteria: (a) use for background music and (b) be
There are companies including Triad, Atlantic Technology, and Snell that
can provide in-wall or incabinet speakers of very high quality. Of these,
Triad has done a better job and provides a more complete line of speakers,
across a broad spectrum of quality and price points. Atlantic Technology
and Snell, while both building excellent speakers, have a much more
limited selection of such speakers.
