”Overall this is a cracking all-rounder that’s sure to please, and you certainly won’t find better at this price, so the Signa S4 comes recommended. ’Trusted Reviews’ - Recommended.

Certified, Dolby Atmos sound

Featuring twin, upwards firing speakers, the Polk Signa S4 is a certified Dolby Atmos soundbar. Atmos means that you get to hear special effects whizzing overhead. From aircraft or space ships to tropical rainstorms, everything sounds far more realistic with Dolby Atmos (compatible Dolby Atmos source required).

Dedicated centre channel for crisp dialogue
With its own, dedicated speaker, dialogue sounds crisp and clear. The dedicated speaker makes speech easier to discern. The central speaker positon also helps sync the sound with the image.

Polk VoiceAdjust technology
We've all been there. You're watching the latest blockbuster and you can't hear the words - it's all just mumbled! Help is at hand with Polk's VoiceAdjust technology. Working in conjunction with the dedicated centre speaker, VoiceAdjust lets you adjust the balance, making the vocals crisp and clear - whatever you're watching.

Powerful bass from a separate subwoofer
As you'd expect from one of the most highly respected names in the speaker business, sound quality leads its class. For the sort of dynamic punch demanded by action movies, the Signa S4 uses a separate subwoofer. With its dedicated woofer and amplifier, the Polk's punch is leagues ahead of a typical TV. The bass is also precise, so that soundtracks are driven along with verve and attack. The wireless connection keeps the clutter down too.

One-button EQ for simple access to the best setting
For optimised sound, the Signa S4 features one-button EQ mode. Simply select ‘Music’ or ‘Movies’ and the soundbar optimises the sound output to best suit the source. Night mode adjusts the sound for a reduced dynamic response – creating less disturbance for those nearby.

Bluetooth music streaming
More than just a soundbar, this Polk soundbar is also an effective music player. Thanks to a built-in Bluetooth receiver, you can link your smartphone, PC, laptop or other device with Bluetooth and stream your stored music or music services such as Spotify. It means that you'll not only enjoy superior TV sound but also have a quality system for your music, too.

Easy to set-up
For the highest quality link, take advantage of the latest eARC (enhanced Audio Return Channel) HDMI connection. Don’t worry if your TV doesn’t have eARC, the HDMI socket is also backwards compatible with ARC. For even older TVs or games consoles, there are also optical and 3.5mm analogue inputs.
