90-RT
High Performance In-Wall Loudspeaker
9 5/8" Diameter
Big sound from speakers you won’t see, on a budget.
Fill any room with great audio without even seeing your speakers, with this large-diameter stealth in-ceiling speaker. A lightweight Polypropylene Cone and sensitive Silk Dome Tweeter baffle can be angled for superior off-axis performance. Use the Reflective Room Compensation Switch to digitally compensate for “reflective” rooms, giving you extraordinary placement flexibility. The innovative addition of the woofer driver behind the main speaker adds surprisingly deep bass response where it’s least expected: in your ceiling. You won’t see the value, but you’ll certainly hear it.
Full-Range 3-Way Driver Array in the Smallest Diameter Innovative new patent-pending design! It’s like having a full-range, full-size speaker in a small inset lighting fixture. Adding a woofer for low frequency response frees up the midrange and tweeter for more efficient detail. To do it, we designed a deep well and mounted the Cassini oval woofer above and behind the main driver array. This innovative deep diagonal positioning allows the 90-RT cutout to be just 9" in diameter. This full-range 3-way driver array results in the kind of broad coverage and big performance usually achieved only with…bigger speakers!
Practically invisible grilles and minimal flanges New design! No other moderately-priced built-in speaker is this invisible. Vanishing Series Built-In Speakers feature our exclusive wafer-thin Sheer-Grille, a magnetically-secured grille that protrudes only 7mm from its surroundings. That’s just this much ----. Painted to match your décor, Vanishing Series Built-In Speakers are virtually indistinguishable from their 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.
Timbre-Matched to Polk Audio RTi Speakers Match Vanishing RT speakers to RTi Series Loudspeakers. Timbre-matching with the same internal components, and the same lightweight polymer composite cone material, insures utterly seamless blending from speaker to speaker. Use Vanishing Series Speakers to build a system or complete an RTi existing system.
Dual Bandpass Bass Ports Bandpass Ports are the way to go when you want high efficiency in small enclosures. Each Vanishing In-Ceiling Speaker sports dual Bandpass Bass Ports, smoothly funneling the angled woofer’s detailed low-frequencies down around the midrange and tweeter array. The port design eliminates “chuffing,” so your small, practically invisible in-ceiling speakers achieve superior full-range blending and broad coverage with surprisingly deep bass.
Easy Installation Puts the architectural elegance of “invisible” speakers within reach for anyone. In existing closed ceilings, use the Perfect Fit Template for one-cut, pop-in simplicity. Achieve secure, vibration-free efficiency with a simple turn of the patented Rotating Cam system. Pre-construction brackets are available for new-build or open-ceiling retro-fitting. Our precision-engineered minimally flanged design lets you get professional results with no additional drywall work.
