We build performance speakers not furniture or hidden speakers - in-wall speakers are horrendous sounding

I agree up to a certain point. Those Mini-Ts would eventually fit in there (note that I made it easier for you through color choice) *if* the stands would be less obtrusive and in a more matching color. The center speaker is a no go but for a stereo setup we don't need it. Amps can visually disappear unless you insist in having an "equipment rack" (IMHO they're just ugly glorified storage shelves). This leaves the subwoofer very proud and visible, maybe this vertical arrangement of 3 drivers isn't the best from an esthetic pov?
C'mon James we can do better if we design for living (or shisha

) rooms not for man caves. Help the audiophiles with a high wife acceptance factor and sales will go up through the roof.
