Creating an unrivalled sense of immersion, the Polk Signa S4, Dolby Atmos certified soundbar brings a new dimension of sound to your listening experience.

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.

Get more from your movie nights, with the Polk Signa S4.

Rated 5 out of 5 by from Great sounding Soundbar with external sub I purchased this Soundbar after hearing it in the Southampton store and the price was great. It wasn’t a brand I had heard of before but was reassured but great knowledge and advice from staff.

Rated 4 out of 5 by from Great sound but NOT Samsung TV-friendly! I bought this from Richer Sounds after a they had dealt in a very positive way with a TV I had damaged which I had bought from them. A few months later, since my 5.1 sound system was 15 years old it desperately needed replacing so I had decided on either a Samsung or Sony sound bar but when I spoke with one of the stores they said the Polk S4 was just as good if not better and was a lot cheaper. So I went for the Polk even though I didn't know the brand. It was delivered and it sounded incredible. However, after a short time I noticed when the TV was left on certain channels, the sound bar did not connect up again properly when the TV was then turned back on and no sound came out even though it was properly set to send the audio through the sound bar. Richer Sounds dealt with the issue amazingly and send a replacement and a different HDMI cable but the problem persisted and it was concluded that this Polk product did not properly communicate with my Samsung TV. I ended up returning the second Polk sound bar and traded up to a Samsung sound bar which sounds equally impressive but is quite a bit more expensive. If your TV isn't a Samsung then definitely consider the Polk.

Rated 5 out of 5 by from Plug in and play straight out of the box ! I bought this a week ago and so far so good - linked it to a Toshiba 65 inch and a huge improvement on the tv’s speakers - the wireless subwoofer packs a punch and the whole system looks and sounds great - and for the price - it knocks its rivals out of the park !

Rated 5 out of 5 by from Great value for money Good build quality, good sound quality. Can’t see it being beaten for the money. Richer Sounds are always helpful and give you options but don’t upsell. Pleasure to do business with- will continue to buy audio visual equipment from them.
