Exactly what I expected
Crutchfield Customer Review (What's this?)
I am building a new home and had these installed where my rear surrounds will go. For my installation, the plastic part was screwed to a ceiling truss, and a single strap was screwed to the opposite truss. Very simple, and now I know that the drywallers will do a great job.
Pros: Perfect fit for my Klipsch speakers.
Cons: Had to examine the pieces to understand how everything was to be installed. It's a very well engineered product but needs some simple explanations on how to install. I would guess that 90% of buyers will figure it out just fine.
