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.

Vanishing 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 décor, 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 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,” 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.

All Polk products are made using the best materials and the most advanced manufacturing techniques. They pass the industry’s most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk loudspeakers are built to perform for a lifetime.

    I'll admit I was a little skeptical at first considering I'd never heard of Safe&SoundHQ before. After doing some homework over at the Polk website and checking there Authorized Dealers list, I just couldn't resist the price on these.

    Installed these along with 4 80f/x-rt and a powered sub woofer to make up my 7.1 system in my living room and all I can say is WOW!!! For a predominantly in ceiling setup (sub is floor standing), I think sound is fantastic.

    Also they staff is more than happy to answer and questions you may have in terms of installation, speaker positioning, recommendations and/or issues. Always received a timely response whether it was by phone, email or chat.

    If your on the fence pull the trigger... let me tell you, I am more than glad that I did.

    Kudos from a truly satisfied customer.

    Quality Speakers

    I have researched speakers for about 2 months now and I haven't been able to find a single bad review about these speakers. While some brands I was researching had reviews of sounding to harsh, dull and unrealistic Polk Audio was one of the only brands that was applauded for its clean, accurate and realistic sound in its price range. I decided to order these open box units from Safe and Sound Hq and save some money. These units not only shipped quickly, they arrived looking perfect. I am so happy i decided to order from this company, and even more happy i chose Polk Audio as the brand of speakers to be used in my home.
