    • Speaker Type: Center channel
    • Enclosure Type: Infinite baffle
    • RMS Power: 75 watts (The maximum amount of continuous power the device is able to handle.)
    • Peak Power Handling: 150 watts (The maximum amount of power an electronic device, like a speaker, can handle without damage. This refers to short bursts of power, while root mean square (RMS) power handling indicates the amount of continuous power a device can sustain. Higher levels of distortion can also occur at peak power levels when the device is powered beyond its recommended usage.)
    • Impedance: 8 ohms (Describes the resistance of an electric signal throughout the system. Devices with low impedance require less power to deliver optimal signals but are more at risk for damage from overloading. Higher impedance requires more power but is more protected from overload damage.)
    • Minimum Frequency Response: 30 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
    • Maximum Frequency Response: 27 kilohertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The maximum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
    • Sensitivity: 90 decibels
    • High Resolution Audio: true (Hear music the way musicians and sound technicians intended it to be heard. Products that support hi-res audio deliver audio signals with a dynamic range and bandwidth far greater than that of a standard CD so you'll be able to enjoy pure music with outstanding sound quality. The device supports high-resolution audio signals, which more closely resemble the quality of music as it was originally recorded, with more texture and detail than can be heard via typical music streaming services or CDs.)

Whats Included
  • Vanishing Series RT 5.25" In-Wall Center-Channel Speaker

Q: Given the tweeter has a swivel function, can this be mounted vertically without sacrificing too much separation of L / R channels?

A: The swivel feature of the tweeter with the 255CRT allows for a 15 degree adjustment. Center channels generally do not have a great deal of influence on left and right channel separation. That is more to do with left and right speaker, dispersion, placement, and content material.

Q: I already have the polk RC85i Speakers installed and would like to know if this center channel speaker will be comparable with these for a proper sound balance. Thank you

A: Hello, the Polk Audio 255C-RT In-Wall Center Channel speaker will make for a fantastic pairing with your existing Polk Audio RC85i speakers.

Q: Not quite sure how to ask this. Can this be mounted in the ceiling? And if so, can you "point the sound" to be optimally set up?

A: Hi Mike, Yes, the Polk Audio 255C-RT can be installed in a ceiling; the swivel-mounted tweeter lets you aim the sound toward your listening position for a better listening experience.

    very good overall

    easy to install, great sound, good price. I would definitely recommend. My only complaint is that if you want to paint the grilles to match the walls you need to remove the cloth film that lines the grille but they tuck it behind the grille mount so unless you cut the cloth to get a hold of it you cannot easily remove it. Once you do remove it, it is basically impossible to put it back in and have it look like it was not removed. i.e. the film bunches up because it cannot be tucked in to the grille mount. The rear surrounds I got from polk were easy to remove and replace the cloth film so it looked like new

    Awesome Speaker

    I purchased the Front and this Center for my Theater/Studio. Honestly my first in-wall speaker purchase. It was simple and easy to install and sounded great right off. Sometimes it's hard to tell where the sound is coming from as the speakers are really transparent in a good way. I would have to say these are my first Polk speakers and I am sold on purchasing more Polk Audio in the future.
