Crutchfield Customer Review (What's this?)
Decent rough-in brackets. They are worth not having to worry about centering the speakers after sheetrock. I purchased 4 of these for surrounds in a tray ceiling. easy to use and nice clips built in to hold the wire. I only wish they were cheaper. $5-$10 would be more reasonable for what they are.
Pros: layout of speakers ahead of time will save frustration during trim out.
