Polk Audio 90-RT 3-Way In-Ceiling Speaker for Mains, Rear or Side Surrounds

The Polk Audio 90-RT in-ceiling speaker is a powerful and versatile audio solution that seamlessly blends into your home's decor. Designed to deliver big, room-filling sound while remaining discreet, this speaker is perfect for use as stealth mains, rears, and side surrounds in a high-performance home theater setup or for bringing dynamic sound to alternate zones in your main listening room.

Featuring Polk's exclusive wafer-thin Sheer-Grille, the 90-RT protrudes only 7mm from its surroundings, making it virtually invisible to the eye. The Sheer-Grille's nearly transparent, ultra-small perforations are acoustically inert, allowing for dynamic, unimpeded sound and more uniform coverage, even in larger rooms. These speakers are timbre-matched to Polk's RTi speakers, ensuring a seamless blending of sound when combined with traditional and built-in speakers.

Powered by Dynamic Balance and Polk's Dual band-pass bass ports, the 90-RT in-ceiling speaker delivers Hi-Fi sound with broad coverage and deep bass, even at low frequencies. The 3-way driver array, including a 3.25" midrange driver, 9" subwoofer, and 0.75" dome tweeter, produces a big, full-range performance from a deceptively small in-ceiling speaker that protrudes only 0.3" from its surroundings.

Designed to offset reflective surfaces and prevent sound distortions, the 90-RT is easy to mount and install. The included precision flange, available pre-construction brackets, and the patented rotating cam system ensure a secure, vibration-free installation. This in-ceiling loudspeaker truly vanishes into the ceiling, giving you a clean, clutter-free look and allowing it to become the center stage of room-filling sound. You can even paint the wafer-thin sheer grille in any color to easily blend it into your home's decor.

Polk's unwavering commitment to quality, reliability, and craftsmanship has made it one of the most trusted names in home audio. By bringing out the best in surround sound systems and acoustic excellence, the 90-RT allows you to sit back, relax, and listen with your heart, immersed in a captivating and immersive audio experience.
