No other line of custom install loudspeakers in this price-range offers you more flexibility and performance. The SC-C is a purpose-designed centre channel speaker for SC Series built-in systems.

  • One-cut easy installation in existing walls or in new construction
  • Dual 5 1/4-inch polymer composite midwoofers
  • Dynamic Balance silk dome tweeters with powerful neodymium magnet structure
  • Paintable grilles & flanges make SC Series speakers virtually invisible
  • Durable, moisture-resistant materials like stainless steel hardware and a powder-coated, rust-proof aluminium grille

Now, you can build a completely stealth home theatre system, including a timbre-matched centre 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 its price range.

This speaker?s wide dispersion design guarantees uniform sound coverage, and seamless surround blending, even in larger rooms.

  • 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 theatre system.
  • A 3/4-inch dynamic balance silk dome tweeter, with powerful neodymium magnet structure, delivers detailed highs and dynamic, realistic effects, for excellent imaging (even in off-axis listening positions).
  • 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.
  • 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 aluminium 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 centre 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.
