A Custom Install Center Channel Speaker

No other line of custom install loudspeakers in this price-range offers you more flexibility and performance. The SC-C is a purpose-designed center channel speaker for SC Series built-in systems. Now, you can build a completely stealth home theater system, including a timbre-matched center channel speaker, without breaking your budget. As with all of our mid-level loudspeakers, its performance is head-and-shoulders above that of anything in it price range. Dual 5 1/4-inch polymer composite midwoofers, tuned to eliminate resonances and distortion with our exclusive Dynamic Balance® technology, do the bulk of the hard work in your SC home theater system. A 3/4-inch silk dome tweeter, with powerful neodymium magnet structure, delivers detailed highs and dynamic, realistic effects, for excellent imaging (even in off-axis listening positions). This speaker’s wide dispersion design guarantees uniform sound coverage, and seamless surround blending, even in larger rooms.

SC-C Features:

One-cut easy installation in existing walls or in new construction, for pros or DIYers alike, with no extra assembly and no additional cutting. (Pre-construction brackets are available separately.)

Polk’s exclusive Rotating Cam system ensures stable, secure, vibration-free placement with the turn of a screwdriver.

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.

Dynamic Balance silk dome tweeters, in aimable swivel housings, deliver clear and detailed highs, without fatigue, for greater accuracy and more realistic imaging.

Paintable grilles & flanges make SC Series speakers virtually invisible.

SC Series built-in speakers share cutout sizes and hardware components with other Polk built-in speaker series, so you can more easily upgrade your built-in speakers at any time.

Durable, moisture-resistant materials like stainless steel hardware and a powder-coated, rust-proof aluminum grille allow you to install SC Series built-in speakers in extreme install locations like kitchens, bathrooms, and transitional areas like sunrooms and covered porches.

The SC Series is timbre-matched to all other Polk loudspeakers, for mix-and-match system-building and seamless, speaker-to-speaker perfection.

The SC Series features three of the most advanced built-in loudspeakers you’ll find: A single compact built-in loudspeaker that brings actual dynamic stereo sound to locations where two speakers just won’t work; two high performance IP-ready loudspeakers, allowing whole-home audio networking on a budget for the very first time, and a high performance built-in center channel speaker!

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.
