The Polk Audio 50-RT is the smallest, most "invisible" full-range in-ceiling speaker. It's packed with technology and built with performance in mind. Its lightweight polypropylene cone and sensitive silk dome tweeter can be angled for superior off-axis performance. Plus, its reflective room compensation switch dampens the effect of "reflective" rooms, affording you extraordinary placement flexibility. The innovative addition of the woofer driver behind the main speaker adds unparalleled depth and dynamics to this tiny performer.
