VS65-RT features Polk's patented Power Port bass venting system that eliminates turbulence for bigger, more efficient deep bass impact in this easy-to-place, single-woofer in-wall speaker. Recommended for use as left and right front channel speakers, stealth side or rear surround speakers in an RTi theater system setup, or for superior dynamics in practically invisible multi-zone music systems. Virtually-flush mounting with a minimal-flange design means this speaker never attracts attention by its looks, only by its performance. Equipped with a Dynamic Balance woofer and a silk dome tweeter it delivers solid bass, detailed high-frequency response with crisp, clear imaging. Timbre-matched to Polk RTi speakers for seamless blending from speaker to speaker in systems that combine traditional and built-in speakers.
