Its dual bandpass enclosure delivers deep bass with minimal distortion, while the ultra-thin 7mm Sheer-Grille ensures a sleek, flush ceiling look. Designed for easy installation with a rotating cam system and paintable grille, it integrates seamlessly into home theater or stereo setups for detailed, room-filling audio.

## Description

Experience room-filling, detailed audio with Polk's Vanishing Series 900-LS In-Ceiling Loudspeaker that hides away in your ceiling and yet produces extraordinary sound quality for your movies, music, and TV shows. It is equipped with a 3.25" Dynamic Balance Driver, a 6" x 9" Dynamic Balance Cassini Oval Woofer and a 0.75" Ring Radiator Tweeter that delivers smooth, detailed highs and accurate lows for an unparalleled musical experience. Featuring dual-ported bandpass enclosure, the loudspeaker offers deep, impactful bass and minimizes resonances for crystal clear audio output. On the front panel, it has a reflective room compensation control switch that allows you to digitally compensate for harsh reflective surfaces, such as smooth walls, glass windows, and hardwood floors for a smooth audio quality. Pair with Vanishing LS Series center channel and in-wall speakers for a home speaker system, or use in a 5.1 or 7.1 channel home theater setup with Polk's traditional floor-standing or bookshelf stereo speakers. These stereo speakers feature a rotating cam stabilizing system that allows for quick and easy installation, while the paintable wafer-thin Sheer-Grille makes the loudspeaker virtually indistinguishable from its surrounding. All LS speakers can be installed in new or existing constructions using optional mounting brackets.
