Product Details

Polk Audio 8" Round In-Ceiling Loudspeaker, Model TC80I

Excellent Performance, Professionally Matched To RTiA
Mix and match TCi In-Wall/In-Ceiling Loudspeakers with Polk Audio RTi Series loudspeakers to create a voice-matched system boasting a realistic surround sound environment without the space requirements of traditional speaker systems (RTi front stage, TCi rear surrounds for example).

Dynamic Balance™ polymer composite driver for smooth wide-range response with low distortion.


  • Aimable 1" silk dome tweeter with neodymium magnet for clear, detailed highs and direct control; excellent imaging even for off-axis listening positions.
  • 15-degree Offset Drive Unit for more midrange clarity and directionality.
  • Wide dispersion design for uniform sound-coverage throughout even large rooms.
  • Durable, moisture resistant materials, including Butyl Rubber surrounds, for safe use in kitchen, bath & sauna.
  • Infinite Baffle Tuning uses the virtual enclosure of in-wall space for superior bass response.
  • Paintable, powder-coated Aluminum Grilles allow TCi Series speakers to virtually disappear in your room!
  • Conveniently accessible front panel controls: Tweeter Level Switch offers flat and –3db selection for more sound control, and the Wall Distance Toggle Switch flattens frequency response when installed near a corner or adjacent wall.
  • Installation is easy as 1-2-3: cut one hole, feed the wires, and simply drop the speaker in. Rotating Cams secure the speaker safely with no extra assembly or mess.
  • Rough-In kit available.
  • Sold singly (packaged one per box). Single units can be used for center channel applications in stealth installs!
  • Perfectly timbre-matched to the whole Polk Audio RTi Series of high performance loudspeakers.
