Review on OSD Audio ACE500 - Thin Bezel Trimless 5.25-inch In-Ceiling/In-Wall Speaker Pair - 75W by Alicia Jones

Can't get it working for a few more weeks but would like to start a review to maybe help others. Mounting screws for ACE400 have very soft heads. I gathered a few on my first install attempt. I then attempted to thread the screws into the unmounted speaker and found that the levers that rotate and grip the backing of the drywall do not stay vertical and cause sticking. After fully tightening and then backing out each lever, I avoided further rounding of the heads. It seems that once caved in they get the right threads and make it a lot easier to install once in the ceiling/wall. I'll update this review once I've linked it.
