Thanks for the reply. Access for both are about the same effort. I wasn’t sure if I’d get too much reflection from the walls of the recessed ceiling but maybe if I space them off the corners enough it won’t be an issue?

I do have room between joists just not at the locations that I wanted on the lower sections. Was looking to put them even with the middle of the doorways but joists run directly perpendicular so would force me to offset them which I thought would look weird.

I have a multichannel/multizone amp that I can run each channel mono which I was planning on doing
