Polk Audio RC6s In-Ceiling Stereo Speaker (Single, White)

This speaker is designed specifically for a situation where stereo sound is not optimal; for example, in the kitchen or dining room. By placing a left and right channel tweater, the sound is mixed in a single speaker. This does mean you have to run both the left and right channel wire to the speaker. The best use of this speaker is to have non-directional sound in each room rather than to blast your one stereo in order to hear it from every room.

The Polk RC80i utilizes a eight-inch dynamic-balance, mineral filled polymer-composite cone with a rubber surround that outlasts cheaper foam surrounds, as well as a one-inch ring-radiator tweeter with a 15-degree swivel mount. The swivel-mounted tweeter is aimable for direct high frequency control that ensures spacious imaging with amazing clarity, and well-balanced sound in any listening position, even off-axis listening positions, rather than in just a small sweet spot. Constructed of rust resistant hardware and durable, moisture resistant materials, the RC80i is safe for use in bathrooms, kitchens, saunas, or even under outdoor eaves, and a glass-filled composite baffle that provides a dense, acoustically inert platform for the speaker's high end components.

This unit features strong composite driver baskets that keep moving parts in rigid alignment, a wide-dispersion design for even sound-coverage throughout even large rooms, and a
wall-distance toggle switch that flattens frequency response when installation requires. placement near a corner or adjacent wall. The RC80i also features a tweeter-level switch that lets you tailor the highs for your room acoustics, and is timbre-matched to the Polk Audio Monitor Series for seamless, enveloping imaging when used in a home theater system.
