”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.

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

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.

Rated 4 out of 5 by from good looking and great sound Got this about a month ago, firstly was really impressed by the packaging. Easy clear and didn't fill the room with polystyrene! Simple 2-page instructions with pictures made setup a breeze. First time using HDMI e-Arc so took a little while to figure that out on the TV but after the whole system was up and running in moments. Remote is simple and easy enough to use. The sound is clear and crisp when watching tv/films and the bass is quite subtle even though I have the sub right next to my sofa. It can be heard and felt if you crank up the level on the remote if you need it but for the most part it's fine. The night mode is really useful for keeping the disturbance down and the 3 levels of voice priority are also handy. Overall very happy with the system and it's a good-looking and unobtrusive bit of kit.

Rated 4 out of 5 by from Excellent sound at a great price Pros : Great sound, deep bass, no speech sync issues, very simple set up, Cons: Mutes itself while changing volume - not sure why but this happens every time the volume is turned up or down and means if you happen to be changing during a speech part of a movie then you're going to miss it and have to rewind a few seconds. Annoying, and still looking for a fix.

Rated 5 out of 5 by from Amazing sound bar punching way above its weight Planning to spend under £400, but wanting a 3.1.2 Sound bar ideally with Dolby Atmos, a wireless sub and great all round clarity and sound, the spec and reviews of the Polk S4 were good enough for me to take a chance on it and I’m glad I did. Having heard the Denon 416 I was going to order one, but luckily before I did I saw and read the spec of the Polk Audio Signa S4. I’d never heard of Polk and so decided to visit my local Richer Sounds (Maidstone) for some advice and am glad I did. The Polk S4 wasn’t on display to test, but the Denon was along side an older model Polk sound bar which allowed me to hear them back to back. I was amazed by how good the Polk sounded. The Denon sounded good, but the Polk sounded that much better in every way (and that’s an older model without Dolby Atmos etc) so I could only imagine how good the S4 would be. I asked if they had any of the S4’s in stock and they had one which they received that morning so I had to buy it. I’m still running the speakers in, but to date the sounds been perfect and only getting better with each use and it looks as good as it sounds. I would highly recommend this product.

Rated 5 out of 5 by from Big sound for my LG C1 65 Inch TV Took a bit of tweaking to get the perfect setup with this unit as it doesn't have fancy echo technology, but raising the front of the sound bar by a small wedge gave the right direction to bounce the Atmos speakers of my ceiling while sat in my smallish living room, also placed the sub woofer on its side w speaker forward as to rumble my ears and not the whole building and the result is impressive. Once you understand that Dolby Atmos is not going to bring chopper blades one inch from your ears and tanks driving over your head you can relax and just enjoy the odd surprise of being immersed within Dolby and non Dolby content...or you can Google the top 10 five second Dolby Atmos moments of all time (seriously) it's not extensive! What the polk S4 does well is open up the soundstage nicely for all content, adding gorgeous bass and up direction speaker's shooting sound over you, watching the opening scenes from Roma on Netflix is really nice if I'm honest and 8/10 for this unit is fair! ...I'd be feeling pretty flush to spend 3x the amount for a slight upgrade though tbh! Would recommend and think you'd need to go £500-£700 with surround speakers to maybe get better

Rated 5 out of 5 by from Best £300 I've ever spent on tech I've had this soundbar for few weeks now and it's made a massive improvement to my movie enjoyment. I thought my Oled TV had good speakers until I connected the soundbar! I have a through lounge so I probably don't receive the full surround sound potential of the Polk soundbar (But it's still incredible). When it arrived my wife said "oh another toy" but she's now eaten her words, she loves it too. It's got some power behind it and it really rocks the room without any distortion, so much so if the base is up sometimes you end up jumping out of your seat. The vocal enhancer is amazing! Even when all the action is kicking off you can still here every bit of dialog and I don't have to ask my wife "what did they say". I have an old school Denon Hi-fi so I do really appreciate good quality audio and this Polk soundbar doesn't disappoint! The sub gives out so much base I have to turn it down when listening to music and major action films. Set-up is so easy, just connect the cables and it's done. Another nice feature is when you turn on turn off your TV the soundbar opens and shuts down automatically. I personally don't think you could by better for the money and it will improve your movie nights so much! Even your terrestrial view is amazing, it up scales even normal content so much! Again another purchase from Richersounds, the go to place for any electrical purchase! Paul from the Croydon brunch as helpfully as usual.

Rated 5 out of 5 by from Premium quality The Polk Audio Signa 4 has all the premium perks you look for at a bargain price. Only one connection Hdmi eArc, but for me is ok as is all I needed and have enough spare ones in the TV.

Rated 5 out of 5 by from Great sound great brand I bought this as a replacement for a market leader soundbar which had no Dolby Atmos built in I was not sure about the brand at first as I knew little about Polk.My scepticism was short lived this system truly delivers great bass from the sub woofer easy set up and boy does it deliver rumbling sounds around the living room pretty good over head sounds from the 2 up firing tweeters over all I would highly recommend this product the sound and quality surely make this sound like a high end branded product

Rated 5 out of 5 by from Just amazing for the price! I bought this sound bar last week at Richer Sounds Romford. Joel was brilliant in guiding me to what I needed and explained everything so clearly. The quality and sound are amazing and the depth of bass is very good. I would have no hesitation in recommending this along with Richer Sounds in Romford.
