Paradigm also has the Premier line of speaker stands and wall mounts. I checked the site and it lists only three mounts, none of which appear appropriate.

I recently had to replace one of the grilles on my towers and Paradigm shipped one over - I had to pay for it, but they had it none the less. I would follow Gonk's advice and ask Paradigm if they can sell/ship over a new wall mount for you.

Best of luck!
