Polk Audio RC80i 100W Ceiling Speaker 10 3/4" (Pair) The In-Ceiling Beast The Polk Audio RC80i 100W Ceiling Speaker 10 3/4" (Pair) features a beefy 8' woofer to produce the maximum amount of bass from an in-ceiling speaker. Perfect for areas requiring big, rich sound without the big speaker cluttering up your room. Its wide dispersion capability means you'll hear great sound no matter where you are in the room. Out Of The Box Into The Wall Installation RCi is incredibly easy to install. Wire them up, pop them in the wall or ceiling, screw down the Rotating Mounting Cams with a screw driver, pop the grille on, turn on the stereo and you're done. Suitable for Semi-Damp Locations* RCi series speakers are also suitable for areas such as bathrooms or under the ceiling of an enclosed porch. Stainless steel hardware and powder coated aluminum grille will not rust. *RCi series are not suitable for outdoor use. For oudoor applications, use our Atrium Series speakers. Swivel Tweeter You can aim freestanding speakers, so why not installed speakers? All RCi speakers feature a swiveling tweeter* to allow you to aim it toward the listening area for greater accuracy. *excludes RC6S, which has two fixed position stereo tweeters. Dynamic Balance and Klippel Optimization Like all high quality Polk speakers, the dome tweeters and polymer drivers in all RCi series speakers are both Dynamic Balance and Klippel Optimized. Dynamic Balance allows us to see the operation of the component on a microscopic level, reducing or eliminating artifacts that color the sound. Klippel Optimization ensures the speaker will perform well at both low and high volumes levels. For more information, click here for Dynamic Balance and here for Klippel Optimization. Blue Polymer Woofers with Rubber Surround Provide excellent damping and bass response while resisting deterioration. Your RCi Speakers may last longer than the house they're installed in. Other speakers use flimsy paper cones and foam surrounds that can fall apart. Timbre Matched The RCi Series speakers are timbre matched to our freestanding speakers - such as Polk Monitor, TSi and OWM series, just in case you need in ceiling surround speakers to match your freestanding fronts.
