About the Polk Audio 90-RT

The Polk Audio 90-RT Full-Range Bandpass Dual-Port In-Ceiling Loudspeaker delivers big sound, yet vanishes into your room's decor. The 90-RT is perfect for use as stealth mains, rears and side surrounds in a high performance home theater, or for bringing dynamic sound to alternate zones from your main stereo listening room.

  • Dual bandpass bass ports are highly efficient in small enclosures and smoothly funnels the angled woofer's low frequencies down around the driver array, eliminating chuffing
