I will be constructing a wall in my HT room. The purpose being to build-in the TV and front 3 speakers. The final result would be a flat wall with a hole for the TV, and grills behind which would be the speakers.
My question is:
Would placing the axioms behind these grills (not standing out in the open ) greatly affect the sound? I assume that bass response would go up and they may become boomy. If this is not recommended then I may have to leave the speakers "outside" of the wall.

Axiom rules!
