Title: Wouldn't hold 13 pounds..... How are they supposed to hold 20?
Review: I wish I would have listened to the 2 star reviews.... But I went with these because the manufacturer of the speakers I bought (Ascend Acoustics) only sells these so I figured they HAVE to work. Unfortunately I was wrong, and to boot, I accidently tossed the boxes in recycling so I can't return them. Decent concept with poor execution. You simply cannot tighten the clamp tight enough to hold a speaker over 5 pounds. I tightened them as tight as I could and within a few minutes the speakers were drooping. I highly recommend bottom mounts if you have heavy speakers because these stink.....
Is the review positive or negative?
