I have a pair of BPX's that I need to mount on the wall. If I put an
anchor screw into the wall and then hang the speaker from the keyhole
in the back, the speaker tilts out where the cables come out of the
back. I'd like the speaker to sit flat against the wall.

I moved recently. When I had them mounted previously, I had drilled a
hole into the wall right where the cables came out, this way the ends
of the cable stuck into the hole and the speaker didn't tilt. However,
I'd rather not drill any extra holes in the wall this time.

Does anybody have any better ways of mounting these speakers?

I've also noticed in the owners manual that it mentions an optional
mounting plate that mounts on the back of the BPX's. Does anybody know
what good these plates do?

Thanks for any info,
Ted
