LCi-RTS100

OMG! THX!

THX Ultra-2 certification is your assurance of superior-quality sound reproduction. The combination of Polk Audio engineering and THX Ultra-2 certification in the RTS100 produces a speaker that delivers superb realism, deep musicality and sustained dynamic range. The RTS100 works anywhere, from the home theater to the dining room, where high performance is demanded and expected.  

LCi-RTS100 Features:

The RTS100 in-ceiling loudspeaker is the first in-ceiling speaker to ever be awarded THX Ultra-2 certification! To design an in-ceiling loudspeaker that meets the demanding specifications of THX Ultra-2 means you have to take into consideration some serious AUs (AKA “advanced unknowables”), like ceiling height and listening positions. Engineering an in-ceiling speaker to pass this certification has been considered “impossible” for years. As with every THX-certified product, this high performance level assures you the superior sound performance and exceptional dynamic range that will make your home theater the envy of the neighborhood.

Exclusive integrated performance enclosure design ensures “perfect volume” performance in an enclosure that is the same size as the wall cut-out you’ll make, so installing them in existing walls is just as easy as naked stud installations in new-build situations.

The Stud-Lock mounting system (included with LCi-RTS105, LCi-RTS100, LCI-RTSF/X models) creates a rigid platform and snug fit that cuts performance-robbing resonances and structural vibrations to increase dynamic range, clarity and ultimate sound quality.

Interchangeable grilles: Choose paintable aluminum-mesh with 75% open space for unrestricted performance, or the acoustically transparent cloth grille to experience the full-on THX Ultra2 performance level.

Paintable grilles let you build them in, and then forget all about them; LCi-RTS Series practically disappear into any room.

Enhanced, reengineered ring radiator tweeters with specially designed faceplate geometry extend top-end response for incredible details and excellent imaging even in off-axis listening positions.

Our aerated polypropylene cone is the ideal balance of lightweight stiffness (for more efficient action with less distortion-causing flex) and superior damping properties, for spectacular midrange clarity and punchy bass. Dual Driver Designs (in all LCi-RTS models except the LCi-RTSF/X) more efficiently deliver superb mid-range clarity and punchy bass.

Polk Audio’s proprietary, patented Dynamic Balance^® technology allows our engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.

Enclosure stiffening technology reduces distortion and eliminates wasted energy for louder, cleaner performance than any other in-wall speakers.

Specially engineered crossover networks feature more sophisticated notch filters (instead of mere resistors).

Easily accessible custom audio controls allow you to tweak your sound for optimum performance in any installation: Use the reflective room (tweeter) compensation switch to digitally compensate for harsh reflective surfaces, and the wall distance setting toggle to compensate for proximity to corners or adjacent walls.

Solid, resonance-free construction features, including molded composite baskets and a secure pole plate (which physically joins the speaker’s motor structure to the enclosure) ensure zero-vibration performance. With no wasted energy, LCi-RTS Series speakers deliver a much more efficient performance, even at tremendous volume levels.

LCi-RTS Series speakers are timbre-matched to Polk Audio LSi speakers to insure utterly seamless blending from speaker to speaker in systems that combine traditional and built-in speakers.

All Polk Audio 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 Audio loudspeakers are built to perform for a lifetime.
