Polk Audio 90-RT Vanishing 3-Way In-Ceiling Speaker (Each)
Big Sound from Speakers You Won't See, on a Budget
A big speaker that 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.
90-RT Features:
- Vanishing Series built-in speakers feature our exclusive wafer-thin Sheer-Grille , a magnetically-secured grille that protrudes only 7mm from its surroundings. Sheer-Grilles have nearly transparent, ultra-small perfs, and are acoustically inert, for dynamic, unimpeded sound and more uniform coverage, even in larger rooms.
- Painted to match your d cor, Vanishing Series built-in speakers are virtually indistinguishable from their surroundings.
- Reflective surfaces in rooms can make sound brighter and cause image distortion. Engaging the Vanishing reflective room compensation feature (by selecting the low setting) lowers the tweeter level to compensate for reflective surfaces. Vanishing reflective room compensation is a custom audio control that cuts the level only in the 4-5kHz range, exactly where reflectivity destroys sound quality. Outside this narrow 1kHz band, the tweeter retains its detailed and accurate high frequency response, for no loss of realistic musical details.
- Vanishing Series RT speakers are timbre-matched to Polk RTi speakers to insure utterly seamless blending from speaker to speaker in systems that combine traditional and built-in speakers.
- Dual band-pass bass ports are highly efficient in small enclosures, and smoothly funnels the angled woofer's low frequencies down around the driver array, eliminating chuffing, so your small, practically invisible in-ceiling speakers achieve superior full-range blending and broad coverage with surprisingly deep bass.
- Easy one-cut, drop-in installation puts built-in audio within reach, with Perfect Fit templates, a precision flange, and (available) Pre-Construction Brackets; achieve secure, vibration-free efficiency with a simple turn of the patented Rotating Cam system.

Polk's patented PowerPort Bass Venting system greatly enhances the smooth low-end response in this easy-to-place, single-woofer in-wall speaker. It is recommended for use as left and right front channel speaker, stealth side or rear surround speaker 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, but by its performance.
