I am looking for in-wall speakers that angle 30-45 degrees to aim from the wall to the MLP for both front-wide, and for rear-surround. I am interested in using the HTR 7000 for this purpose given its 30 deg angle. Any concerns with mounting these in the wall at ear level aimed at the MLP?

Hi ScottE, From a performance standpoint, the Invisa HTR7000s would work very well in this application. If desired, you could also purchase square grilles for these speakers.

From a physical standpoint, we might have an issue, though. The mounting depth of the Invisa HTR7000 is 5" - and most wall surfaces do not have an opening or depth of 5". (Depending upon the thickness of the drywall, most walls have a total depth of 4" - 4.25".) Happy Listening!
