Concerning a side issue talked about earlier in this thread, about mounting a W100 on the wall, but angling it upwards a bit by using a home made bracket. There is a danger here that I want to point out because I did try something like this when I mounted the W100 in the wall this weekend.

The backside of the wall bracket that holds the speaker goes flush with the wall and doesn't move from this flush position, but the outer half of the bracket, with it bent at an angle upward creates an angle that will trap the speaker after sliding it into the hole making it nearly impossible to get the speaker back out of the wall.
