I have 3 QS8's mounted with the speaker wire connected to the mounting bracket. It takes a bit of work and patience to get a good connection where all of the speaker wire is inside the clamp. That's one design I'd like to see improved somehow. With a single strand wire, it wouldn't be an issue. But, with the 12 gauge multi stand wire, it can be a bit of a challenge.

Slightly longer screws might help, because now when you unscrew them to make the gap to put the wire in, sometimes the screws come all the way out, then you have to take the time to re-insert the screw. (This can cause some expletives to escape your upper orifice, if your're not careful.)
