Polk Audio Signature S55 Review

Polk Audio’s new redesigned speakers have a modern and futuristic look instead of the traditional roughened design of its competitors. As a first-time user, I’m sure you’re bubbling to know the features that make these floor standing speakers worth a pick. So, let’s get started.

Sleek Design

The Polk Signature S55 speaker has a sturdy, solid, and acoustically inert enclosure. You, therefore, don’t have to worry about audio coloration because this enclosure reduces unwanted internal standing waves. Additionally, the non-resonant meddite MDF build, thick baffles, and extra bracing on the subwoofer make sure you get a more life-like sound.

Internally, these signature series speakers have iconic-rounded edges and detailing, whose working concept is derived from some of the choicest acoustic guitars. This way, you end up getting a stylish and performance-oriented speaker that will lighten your living room. Lastly, the computer-modeled anti-diffraction magnetic grilles design makes your S55 speakers achieve a precise fit that reduces sonic interference.

Sound Quality

This washed black walnut Polk S55 speaker has dual 6.5 inches drivers and a 1-inch Terylene high-resolution dome tweeter. They deliver deep bass and produce crispy clear highs up to 40000 Hz for realistic reproduction of vocals and instruments.

There’s a Dynamic Balance Array technology that guarantees clean, full-range sounds as you enjoy your favorite music. So, if you’re planning to upgrade your home theater systems with an Atmos configuration, the Polk Audio S55 speaker will be a perfect pick for you.

And there’s more. The crossover array in these floorstanding speakers means that you can now enjoy music from every spot in your living room by providing a lifelike soundstage experience.

Patented Power Port Technology

The patented power port design in the S55 speakers smoothly transitions airflow between your speaker’s port and your listening room. This provides a much-extended surface area to minimize sound distortion and turbulence in your speakers. As a result, you get a sweet-sounding and more profound bass impact, perfect for TV, music, and movies.


Timbre-matched speakers have the same perceived sound quality for sound, musical note, or tone and the S55 isn’t an exception. It blends perfectly with other Polk center channels, bookshelf speakers, and tower speakers in your multi-channel systems.

For instance, you can have a 5.1 home theater system by blending the S55 floorstanding speaker, S15 bookshelf speaker, S35 center channel, and a Polk Audio PSW108 subwoofer.
