Smaller Basic In-Ceiling Loudspeaker Take practically invisible in-ceiling sound practically anywhere in your home, including the bathroom and transitional spaces like porches and sunrooms, with the MC60. Easy to install, with a 6 1/2-inch midwoofer and 3/4-inch aimable silk dome tweeter, the compact, basic MC60 delivers surprising performance without costing a bundle. Specially tuned for excellent ambient performance, with superb detail and natural musicality, even at low volume. Easy one-cut, drop-in installation puts built-in audio within reach, with Perfect Fit templates, a precision flange, and (available) pre-construction brackets; achieve secure, vibration-free efficiency with a simple turn of the patented Rotating Cam system. Lightweight and stiff polymer drivers provide excellent damping and bass response. Aimable swivel tweeters for greater accuracy and more realistic imaging. Polk’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. Rustproof stainless steel hardware, durable butyl rubber surrounds and powder coated aluminum grilles make TCi Series speakers suitable for high moisture areas like bathrooms, transitional spaces or even under eaves or in the ceiling of an enclosed porch. (TCi series are not suitable for exposed outdoor use. For outdoor speaker fun, use our Atrium® Series.) Paintable grilles let you build them in, and then forget all about them; TCi Series practically disappear into any room. MC Series speakers are timbre-matched to other Polk speakers to insure utterly seamless blending from speaker to speaker in systems that combine traditional and built-in speakers. All Polk 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 loudspeakers are built to perform for a lifetime.
