Makes install easier
Crutchfield Customer Review (What's this?)
Product is a good one. As my installer said, "you can pay the cost now for the brackets, or pay more once drywall goes up when the labor is more intensive to cut out the speaker holes." I opted to pay the costs up front so I could see, and approve, exactly where the speakers would be placed.
Pros: allows for visual "validation" of where speakers will be placed before drywall goes up
Cons: expensive for just a plastic ring.... it adds 30%+ to the cost of the speakers.
