Measuring only 11x7 9/16-inch with an amazing 2 1/2-inch total depth, this compact in-wall speaker fits practically anywhere.

Got an unused nook or a blank space on the wall? Why not put a speaker there?


  • RCi speakers utilise the "virtual enclosure" of your in-wall and in-ceiling space to enhance their bass response and smooth low frequency blending with the midrange.

  • Lightweight and stiff blue polymer cones deliver excellent damping and bass response.

  • Durable, computer modeled, injection-moulded butyl rubber surrounds suppress unwanted cone resonances for a lifetime of reliable sound.

  • Rustproof stainless steel hardware, durable butyl rubber surrounds and powder coated aluminium (in-ceiling) & painted steel (in-wall) grilles make RCi Series speakers suitable for high moisture areas like bathrooms or even under eaves of an enclosed porch. (RCi series are not suitable for exposed outdoor use.)

  • RCi speakers have paintable grilles and practically disappear into any room.

  • RCi 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.
