Our take on the Polk Audio 255C-RT Vanishing RT Series Two-Way In-Wall Center Channel Speaker

The 255C-RT is a two-way in-wall center channel from Polk's Vanishing RT line, built to sit horizontally behind a flush white grille. It pairs two 5.25-inch mineral-composite polypropylene woofers with a 1-inch silk-polymer dome tweeter, and Polk's PowerPort bass venting helps it reach lower than a typical shallow in-wall. At 3.875 inches deep and 6.6 pounds it fits most standard stud bays, and 90 dB sensitivity with an 8-ohm load makes it easy to drive from an AV receiver. It suits anyone building a discreet home theater where the center speaker must match the look of in-wall left and right speakers.

Questions and answers

Does it work as a center channel only?
Yes. It is designed as a horizontal in-wall center channel, so left and right channels need separate speakers.
What amplifier power does it need?
Polk rates it for 10 to 150 watts per channel. Its 90 dB sensitivity and 8-ohm impedance mean most AV receivers can drive it.
How deep is the wall cavity it needs?
The speaker is 3.875 inches deep, and the cutout is 7.625 by 13.125 inches. Leave 3.375 inches of clearance on each side for the mounting dogs.
Is a back box included?
No. It uses the wall cavity as its enclosure, with PowerPort bass venting. A pre-construction bracket is sold separately for new builds.
What comes in the box?
One speaker and one white sheer grille. The pre-construction bracket is not included.
How low does it go?
Polk rates the total response at 30 Hz to 27 kHz, with the -3 dB limits at 50 Hz to 25 kHz. Real bass output depends on the wall and room.
