Over priced but worth it
Crutchfield Customer Review (What's this?)
I am building a new house and going to install the Polk RC80i speakers. I ordered the Preconstruction Ceiling Brackets so I could get the speakers positioned where I wanted them and speed the speaker installation. I am somewhat handy but have never done well at cutting drywall. I though having the brackets would leave the cutting to the pros. I also ordered the XTC 12" Speaker Baffles to keep insulation off the speakers As everyone says these should be about $5 a pair, not $50. Cheap and flimsy. My roof trusses were 24" on center. If you off center the speaker between the trusses (which I needed to do on multiple speakers due to space constraints), the brackets may not be long enough to span the opening. I needed to nail blocks to the side of the trusses to reach the straps. If you do not center the screw in the hole when attaching the brackets, the bracket will move to center itself to the screw. This will move the position of the speaker opening I would say up to an inch. If you have 3 or more speakers in a row, this may be noticeable. Why the 5 star rating for an overpriced piece of plastic that you need to use caution when installing? In my case it would have been very difficult to position the speakers symmetrically in the room and equal distant from recessed lights after drywall without hitting a truss. I slit the base of the XTC enclosures and slid the speaker brackets through the slit. The ID of the baffle is just slightly larger than the ID of the bracket.
Pros: Allows you to position the speakers exactly where you want them.
