Works exceptional with used with Polk 8" preconstruction brackets
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. Per the building inspector (and he is a good guy), in the frozen tundra of Wisconsin you need to have something behind the speakers to prevent air infiltration and moisture issues. That is why I ordered the XTC 12" Speaker Baffles. I slit the base of the XTC enclosures and slid the speaker brackets through the slit. The XTC enclosures fit perfectly. The ID of the speaker baffle is just slightly larger than the ID of the speaker bracket. They work together well. I hate to admit it, but the (overpriced) speaker bracket and XTC baffle together are worth the money.
Pros: Works well with the Polk 8" preconstruction bracket.
