Polk Audio 900-LS In-ceiling speaker

A real standout — but practically invisible

Polk’s Vanishing® Series 900-LS in-ceiling speaker is designed to stay out of sight and out of mind…until you hear the rich, detailed sound it produces. This high-performance speaker hides away in your ceiling, which means you can enjoy great sound in rooms where regular free-standing speakers are an awkward fit.

Advanced 3-way design

The secret to the 900-LS’s compact cutout size lies in Polk’s innovative “Cassini Oval” driver design, which positions an oval-shaped woofer at an angle behind the midrange and tweeter array, in a built-in dual-ported bandpass enclosure. The woofer’s increased surface area and rigid cast basket combine for deep musical bass. This speaker also features Polk’s own advanced version of the classic “ring radiator” tweeter for smooth, detailed highs, along with a 3-1/4″ Dynamic Balance midrange driver, for accurate response across a wide frequency range.

Sound-shaping controls

A wall distance toggle switch lets you compensate for boominess due to installation near a side wall. You also get a tweeter attenuation switch to help you get balanced sound in rooms with lots of reflective surfaces.

Mix and match with Polk’s free-standing LSi M speakers

Use a pair of 900-LS in-ceiling speakers to listen to music in the den, or add more for a great sounding home theater. Vanishing Series LS speakers are voice-matched to Polk’s renowned free-standing LSi  M speakers, so you can combine these in-ceiling speakers with in-walls or free-standing speakers and get harmonious results.

An optional in-ceiling bracket is recommended for installing the 900-LS speaker in a home with new construction.
