Enjoy an enhanced 33 Hz to 40 kHz frequency response with this washed black walnut Polk Audio Signature Series S50 Floorstanding Speaker. It can handle 20 to 150W of continuous power and is equipped with two 5.25" woofers and a 1" tweeter. The down-firing Power Port is a bass port designed to enhance the speaker's low frequency effects. The speaker is bi-amp and bi-wire capable via its two pairs of 5-way binding posts.

Dynamic Balance Acoustic Array

Dynamic Balance is designed to ensure a rich, clean, full-range sound, no matter what you're listening to. It analyzes the speaker's electro-acoustic and mechanical system for improved material selection and more efficient geometry, then pinpoints and eliminates issues that reduce speaker performance before they become a part of the finished product.

High-Resolution Audio Performance

The Terylene dome tweeter is designed to deliver clear and detailed high frequency response at up to 40 kHz for a realistic reproduction of vocals and instruments.

Polypropylene Mid-Range Drivers

Mica-reinforced polypropylene cones with butyl rubber surrounds, ceramic motor structures, and high-temperature Conex fiber spiders combine to create drivers of enhanced efficiency, for clean, clear bass, augmented linearity, lower distortion, and higher durability.

Polk Power Port Deep Bass Technology

The Power Port is designed to smoothly transition the air flow into your listening area. It also extends the overall bass port, providing greater surface area to help eliminate turbulence and distortion, for bigger, more musical, deep bass impact.

Enhanced Sensitivity and Compatibility

Whether you're connecting it to a new digital processor or your vintage rig, the S50 is designed to provide sound reproduction that's spacious, clear, enveloping, and realistic. Plus, it's compatible with many Dolby and DTS surround sound technologies.

Three-Driver Cascading Tapered Crossover Array

The crossover array is designed to provide a lifelike soundstage wherever you are in the listening room, helping to eliminate a solitary sweet spot.

Anti-Diffraction Magnetic Grille

The grille is computer modeled for a precision fit and designed to minimize sonic interference.

Gold-Plated 5-Way Binding Posts

The binding posts are designed to help ensure the most direct, loss-less connection possible.

Acoustically Inert Enclosure

The cabinet is designed to be rigid and acoustically inert to help reduce unwanted internal standing waves to provide less audible coloration.

Dual-Floor-Compatible Feet

The feet are designed for enhanced stability and bass coupling to both carpeted and hard floors.

Timbre-Matched

The S50 is designed with the same components throughout to help achieve seamless speaker-to-speaker blending effects in multi-channel systems.

Polk Audio S50 Reviews

GREAT SOUNDING SPEAKERS

By Joe
Rated 5 out of 5
Date: 2021-01-27

These are the best speakers that I have ever had. I am running a7.2.4 system using all polk speakers and I am blown away how good they sound. When I watch certain movies I can feel the sound esp. the low end. I have an s35 center channel as well as s10's for the back. If you want the most bang for your buck then get these.

High fidelity, nice build

Great build for the price. Sound wise, they are modern sounding and a bit heavy in the 1k frequency. I’ve listened to a wide variety of music and with adjusting the EQ of my receiver for these speakers along with the distance, I’m very happy with the sound. The reason for 4 stars is that I prefer a bit closer to flat frequency response and it’s a little mid heavy, but with EQing and dialing in your receiver settings they can be right in the money. Hard to beat the price for the look and sound.

Great Polk Audio Speakers!

I've been a Polk Audio loyal customer for 25 years. These speakers work as I expected. Very easy installation, connectors are easy to set up, instructions and product registration A+. Audio quality and performance is outstanding. Package was optimal and shipping speed was very fast too

Crisp, Clean Sound

High quality build. Crystal clear sound. Great for a home theater or similar use. Polk Signature Series are very difficult to beat for the cost and frankly provide sound quality of higher-priced brands. It is unlikely you will be disappointed.

for the money, hard to find any better...!

First, B&H was the most affordable on the web for these units when I had purchased these a few months back. Not only that, but free shipping and received a day earlier than estimated. Anyhow, the S50's are pretty fantastic. They upgraded some older Infinity floor speakers and there is a drastic difference in quality and sound. I'm driving them with an older, but high end Denon AVR 2307ci, with a larger Klipsch sub and polk center. Either way, I'm very satisfied with this purchase and feel I could not have found a nicer set of speakers for the money in this configuration. Plus, they're midsize and don't dominate the room, so the wife is happy. When she's not around, I put these puppies to work! I love them.
