Bill, Thanks for the compliment.
I had to replace the bolts that came with the clamps with longer ones. I drilled a hole through the PVC and put a washer, lock washer, and bolt on there. Then I tightened them up.
The only thing about this is you have to mount the can on the tower, then put the speaker in. But, it works really well. The Pro-werks fit great and look great too. I get no movement at all.
I'm working on some instructions with some photos for your http://www.diytowers.com
site. I'll e-mail them to you when I get done.
