I'll see what I can do about sliding the side surrounds forward a bit. I dont have too much wall to work with there. I also have the ability to add 1/2" ply around the box to give mounting flexibility once I see how much real estate the door trim and acoustic panel leave.

Thanks brwsaw for the ply idea. Way easier than 2x4 blocking for future proofing.

I agree with you Nick.

My receiver was 2k less than 2 years ago.... Another receiver so soon is tough to do right now I know. frown. I'm hoping oppo or someone releases an ATMOS stand alone processor that I can add to what I currently have without taking a hit on selling my now "antique" receiver. laugh
