Polk Audio VS 255C-RT In-Wall Centre Channel Speaker

Polk Audio VS 255C-RT In-Wall Speaker

The Polk Audio VS 255C-RT In-Wall Speaker is a high-performance in-wall centre channel speaker from Polk’s Vanishing RT Series, built for home theatres where the speaker should be heard but not seen. It is a two-way horizontal design with twin 5.25-inch drivers and a silk and polymer dome tweeter, mounted in a rectangular frame that sits flush in the wall behind a paintable grille. Sold singly, the Polk Audio VS 255C-RT In-Wall Speaker is the centrepiece of a stealth home theatre: it anchors dialogue to the screen while disappearing into the decor, and it is voice-matched to Polk’s RTi speakers so in-wall and freestanding speakers blend seamlessly in one system.

Why Choose Polk Audio VS 255C-RT In-Wall Speaker?

Buyers choose the Polk Audio VS 255C-RT In-Wall Speaker when a room must look clean but sound like a cinema. A freestanding centre on a console works, but it is always visible and always a compromise on placement; an in-wall centre sits exactly where it should, centred on the screen, with nothing on show except a paintable grille that can match the wall. The twin 5.25-inch drivers give dialogue real body, so voices do not thin out in action scenes, and the dome tweeter keeps consonants clear without harshness. Voice-matching to Polk’s RTi range matters more than it sounds: in a mixed system, an unmatched centre sticks out every time sound pans across the front, while the 255C-RT hands over to RTi fronts invisibly. The Vanishing Series frame uses Perfect Fit templates for a clean one-cut, drop-in installation, and the shallow depth of under four inches fits standard wall cavities. For a dedicated theatre room, a media wall or a living room where visible speakers are not wanted, it is the centre channel that solves the look-versus-sound argument.

Key Features

• Twin 5.25-inch drivers: two matched woofers give dialogue weight and a stable centre image for every seat.
• Silk and polymer dome tweeter: the dome tweeter keeps voices crisp and natural without edginess.
• Vanishing in-wall design: the rectangular frame sits flush in the wall behind a paintable grille that blends into the decor.
• Voice-matched to RTi speakers: blends seamlessly with Polk’s freestanding RTi speakers in a mixed system.
• Perfect Fit installation: supplied templates give a clean one-cut, drop-in fit in standard wall cavities.

Best Suited For

The Polk Audio VS 255C-RT In-Wall Speaker suits a dedicated home theatre room, a media wall installation and any living room where visible speakers are unwelcome. It is ideal as the centre channel of a stealth surround system with in-wall or in-ceiling fronts and surrounds, and as the centre in a mixed system with Polk RTi freestanding speakers. It works with any AV receiver with a centre output, and it suits new construction and renovation projects where the wall is open, as well as retrofit installs where a clean cutout is possible.

Setup and Connection Guide

Use the supplied Perfect Fit template to mark the cutout on the wall, centred on the screen and at roughly ear height for the main seating row, then cut the opening and run speaker cable from your AV receiver’s centre output to the location. Drop the Polk Audio VS 255C-RT In-Wall Speaker into the cutout, engage the mounting system so the frame clamps evenly to the plasterboard, and connect the cable to the rear terminals with consistent polarity. Fit the paintable grille, paint it to match the wall if desired, then run your receiver’s room calibration and check dialogue with a talk-heavy scene before closing up any access panels.

Frequently Asked Questions

Is the Polk Audio VS 255C-RT In-Wall Speaker sold singly or as a pair?

Singly. A surround system needs only one centre speaker, so the Polk Audio VS 255C-RT In-Wall Speaker is sold as a single unit, and the price in this listing is for one speaker.

Can the grille of the Polk Audio VS 255C-RT In-Wall Speaker be painted?

Yes. The Vanishing Series grille is paintable, so it can be finished to match the wall and make the speaker visually disappear into the room.

Will the Polk Audio VS 255C-RT In-Wall Speaker match my Polk RTi speakers?

Yes. The 255C-RT is voice-matched to Polk’s RTi speakers, so it blends with RTi freestanding fronts and surrounds without a tonal step when sound pans across the front of the room.
