Not unrelated, and it might help the OP......

I've always wondered if anyone used a VP100 or 150 in a space that didn't offer the full height requirement of the speakers... simply by allowing it to "hang out" in the front a bit (also getting it past the "lip")...



If it seems unstable hanging off the front, the threaded hole in the back can be used for either "mounting" or "counterbalancing"....
