About Polk Audio SC50

The Polk Audio SC50 is a 2-way coaxial in-ceiling loudspeaker. 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 Polk's 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 and flanges make SC Series speakers virtually invisible.

The SC50 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 50 Built-In Speakers in extreme install locations like kitchens, bathrooms and transitional areas like sunrooms and covered porches.

Polk Audio SC50 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
  • The SC50 is timbre-matched to all other Polk loudspeakers, for mix-and-match system-building and seamless, speaker-to-speaker perfection
  • The SC50 features a single compact built-in loudspeaker that brings actual dynamic stereo sound to locations where two speakers just won't work
