What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
Product Strengths
- Designed to be minimally invasive and slip easily and undetected into any environment
- Polk has minimized the thickness, making it easy to install in most homes
- Build quality is good and the weight has been kept nice and low
- When set up correctly, it projects well and directly forward and has a slight lean to a warmer tone, but nonetheless has great clarity
Product Considerations
- Installing in-wall speakers is not easy, and professional installation is recommended
- Requires a separate amplifier and a way to connect sound to it
- Installation is not recommended if there is no space behind drywall or on solid surfaces like concrete or stone
- Polk's logo on the grill might be a minor aesthetic issue for some who want it to be inconspicuous
- Sound is not really relevant when evaluating the speaker on its own, as it's designed to be used as part of a full system
Takeaway: The Polk Audio 255c-RT is a great addition to a home theatre sound system, especially when paired with other speakers from the Polk Audio RT line. It has good build quality, and its unobtrusive design makes it a solid choice for creating a multi-directional audio experience for watching movies.
What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Legend L600
- Positioning: A flagship floor-standing tower speaker in the Legend series.

Our take on the brand
Polk’s been a major player in the audio world since the ’70s, though they don’t always get the same attention from hi-fi reviewers as some other brands. But they know their niche—mass-market, entry-level products that perform way better than you’d expect for the price. Their R200 model, for example, gets called one of the best under $1,000. If you’re looking for solid performance without spending a fortune, Polk’s stuff is hard to beat.

Klipsch is renowned for its pioneering use of horn-loaded technology in speakers, which enhances efficiency and reduces distortion through their signature Tractrix Horn design. The brand's distinctive "Klipsch sound" is characterized by a bright, dynamic audio profile that some find exhilarating.

Product Strengths
- Sensitivity measures at about 94dB, which is nice
- Output levels are quite good with low distortion and compression when crossed with a subwoofer
Product Considerations
- Linearity of the speaker takes a hit, in part, to the HF boost
- Directivity in the horizontal region is poor with a narrowing response through the midrange
- Listeners sitting to the side of the speaker more than about ±15° are going to suffer from some speech intelligibility issues
- Elevated treble response rises to as much as +4dB above the average sensitivity levels above 8kHz
Comparisons (according to reviewers)
- Vs Reference Premiere (RP) series, the 'II' version of the RP series generally has a more toned down treble
Takeaway: The Klipsch RP-404C II center channel speaker has nice sensitivity and good output levels with low distortion when used with a subwoofer. Consider this speaker if you are sitting directly in front of it and want clear output levels.
