If so make sure u leave yourself a dedicated access panel for all the electronic equipment cabling (AVR, coax, speaker cables, etc.), preferably near or behind your entertainment center hub, if possible (the closet?), for easy access in the future if u decide to move your speakers around (heights, surrounds) or the TV height/location. The access panel can always be camouflaged by a painting or whatnot. Before closing the walls, run some fish rope along to each speaker/coax, etc. location back to the access panel. Leave about 6’ of slack in the wiring in the ceiling, on both ends; be it coax (router extender for instance), speaker wires, etc., if u decide to move the AV plates down to standard height or to a nearby location.
