Our take on the Polk Audio Performance Enclosure

If you're installing your Polk in-wall speakers in a new home under construction, use Polk's Performance Enclosures for the best possible sound. This "in-wall cabinet" is the ideal size for Polk's LC65i, TC65i, or LC65fx in-wall speakers. The engineers at Polk carefully designed the enclosure to enable the speakers to achieve optimum low-frequency response. The rigid MDF construction keeps the bass tight and clean. Polk provides brackets, gaskets, and the hardware needed for installation.

Overview: The Polk Audio custom built LCi Performance Enclosure gives the LCi in-wall speakers the performance edge by hiding a complete, perfect-volume speaker cabinet within the wall before the wall is even completed. The LCi Performance Enclosure is specially constructed of high density MDF and fill material in a size that fits securely between wall studs in pre-drywall construction. Adjustable brackets make pre-construction installation simple. Vibration-damping foam pads ensure rattle-free performance.
