High Resolution HiFi Home Theatre Speaker

Built to bring the big surround sound theatre and music experience into the comfort of your living room, the Polk Signature S30e centre speaker continues in the Polk tradition of High Performance at an affordable price. Featuring Hi-Res certification, a new Dynamic Balance designed acoustic array, precision cross-overs, an anti-diffraction grille, modern cabinet styling and exclusive Power Port bass enhancing technology, you get elevated sound for movies, TV and music in a totally re-imagined design. Polk-expect great sound.

Dynamic Balance Technology Driver Design

Whether upgrading your home theatre setup with an advanced Atmos configuration or enjoying your favourite music, Dynamic Balance ensures a rich, clean, full-range sound no matter what you're listening to. This patented technology analyses the speaker's entire electro-acoustic and mechanical system for improved material selection and more efficient geometry. It pinpoints and eliminates issues that reduce speaker performance before they become a part of the finished product.

High-Resolution Polk Terylene Tweeter

Our Terylene dome tweeter features curvilinear formers that extend response and lower resonance. Its powerful ceramic motor structure also lowers system resonance and extends low- frequency response for better dispersion in the critical midrange, delivering clear and detailed high-frequency response for realistic reproduction of vocals and instruments. Capable of delivering 40kHz to support the latest high-resolution audio files so it feels like you're right there in the studio or concert hall.

Custom Mid-Range Drivers

Mica-reinforced polypropylene cones with butyl rubber surrounds, massive ceramic motor structures and high-temperature Conex fibre spiders combine to create drivers of exceptionally high efficiency, for clean, clear bass, better linearity, lower distortion and greater durability.

Exclusive Polk Power Port Technology

Power Port® is our patented design that smoothly transitions the air flow from the speaker's port into your listening area. It also extends the dungaree bass port, providing greater surface area to eliminate turbulence and distortion, for bigger, more musical, deep bass impact. Plus, it offers 3dB more bass response output than a traditional port.

High Sensitivity and Maximum Compatibility

Works with the most modestly powered amplifier or receiver. Whether you're connecting them to the newest digital processor or your vintage rig, you get sound reproduction that's spacious, clear, enveloping, and realistic. Plus, it's compatible with latest Dolby and DTS surround sound technologies.

Two-Way Phase Optimised Crossover Array

Gives you a focussed dialogue channel that blends seamlessly with other Polk Signature series speakers to deliver an enhanced sweet spot for a more realistic listening experience.

Anti-Diffraction Magnetic Grilles

Computer modelled for a precision fit and enhanced good looks-and made to minimise sonic interference.

Gold Plated 5-Way Binding Posts

Perfect for easy setup, they ensure the most direct, efficient, and loss-less connection possible.

Quality, critically damped Cabinet Design

Strong, rigid and acoustically inert enclosure that reduces unwanted internal standing waves for less audible colouration. And non-resonant, critically damped Meddite MDF construction, ensures low self noise for a more lifelike sound.

Timbre-Matched

Designed with the same components throughout to achieve seamless speaker-to-speaker blending effects in multi-channel systems.

Modern Styling

Curved edges offer a sensual yet powerful look that fits with any home decor—available in a stunning black or white washed walnut finishes.

Limited Warranty, Built to Last

Designed in California and co-engineered in the US and Europe under the strictest quality controls, it includes a limited 5-year warranty.

Product Reviews

Heimkino

"Polk has succeeded in combining American dynamics with European balance with the Signature E series, which has been specially tuned for Europe. The 5.0 home theater set from the S60e, S35e and S20e can inspire sonority, looks elegant and is a real fun charm for demanding film fans."

OnOff

“High performance at an economical price that results in high-level sound for enjoying home theater”

AV FORUMS

"The Polk Signature E Series is a cracking range of speakers that will enhance any home cinema setup they’re added to. The system we reviewed not only looks charming, but also offers excellent value and delivers an undeniably enjoyable sonic performance. The speakers are dynamic and responsive, quickly reacting to transients, while remaining very easy to drive. The centre speaker looks very ‘Polk-like’ and ensures plenty of width at the front of the room."
