True Dolby Atmos Surround Sound

Signa S4 is Dolby Atmos Certified* to immerse you in 360 degrees of surround sound. From added ambience in music to special effects flying overhead, Signa S4 provides an incredibly realistic sound environment. Plus, standard audio played through the Signa S4 can be up-mixed to create a virtualized Atmos experience.
* Requires HDMI eARC connection between sound bar and TV

Advanced 3.1.2 Sound Bar

The Signa S4 sound bar’s advanced seven speaker array was designed to deliver a lifelike Dolby Atmos 3.1.2 listening experience. Its dedicated center channel provides crystal clear dialogue and its optimized left and right tweeters and woofers deliver a huge, wide sound stage. Plus, dual, up-firing speakers take advantage of Atmos’ height channels to send sounds over your head, rounding out your 3D sound immersion.

Polk VoiceAdjust™ – Hear Every Word

Tired of riding the volume control to hear the dialogue during quiet scenes? Have trouble picking out voices when the bass kicks in? Polk’s VoiceAdjust was designed to make sure that you hear every word. This patented technology combines with Signa S4’s dedicated center channel to allow you to raise the volume of only the voices, making them clear and easy-to-understand, while leaving the rest of the soundtrack untouched

Optimized Sound Modes

One-button, preset sound modes optimize the Signa S4 so you can have the best sonic experience for movie watching and music listening. And don’t worry about waking your family or neighbors during late night, binge watching sessions. With Night Mode, one button lowers the bass while increasing VoiceAdjust so you can hear every word, without raising the master volume.

Sets Up In Seconds

Set up is easy: simply connect the included HDMI or optical cable (or aux-in for older TVs) for the ultimate sound quality for any TV—even the latest 8K Ultra-HD TVs. Signa S4 is pre-programmed to work with most TV remotes and it quickly pairs to your mobile device via Bluetooth to stream your favorite music. Lastly, Signa S4’s low-profile design won’t block your TV or your remote and can also be wall-mounted for flexible placement.

50 Years of Engineering The Perfect Home Theater Sound

Signa S4 was designed in our Acoustic Research and Development center outside Baltimore, MD by the speaker experts at Polk. We’ve leveraged over 50 years of American hi-fi loudspeaker engineering so Signa S4 will deliver the thunderous, crystal clear, cinematic surround sound experience you’ve always dreamed of in your home—but at a value you could never imagine.

Perfect for the Price!
Color: Greige, Size: 13"D x 23.7"W x 32.7"H
The bar cart was very easy to put together. I can be "mechanically challenged" and was able to do it myself LOL It's nice and sturdy, the wheels roll smooth when you move it. The size is perfect for the small wall I have it against. I have several bottles of liquor and bartending mixer set on top, and about 20 various glassware on the 2nd shelf. The bottom shelf is taller, and does let you stand larger bottles down there. The one racks will only for the smaller size, but does hold them well.

Decent bar cart, but very annoying assembly
Color: Marble White, Size: 13"D x 23.7"W x 32.7"H
I think it looks nice and is decent value, but this thing is a pain to put together. Instead of just sending 3 shelves, you get 6 pieces to connect together to make 3 shelves. On top of that - they don’t even really connect. It would be 1000x easier if they added a couple of wooden pegs to connect the 2 pieces together. Instead, you have to do a balancing act which is tedious as can be. I ended up super glueing 2 of the 3 shelves togethers after how annoying the first was, so I would highly recommend you do the same. The whole process of putting it together feels like a balancing act. For something so small, it’s about as annoying as possible to put together. Nearly every step requires you to balance something and screw it in. Most of this would be alleviated if, as I said, it was just 3 pieces for the shelves instead of 6. But, you get what you pay for. Overall, I can’t complain too much for the price and result, but I wasn’t a fan of building it. It’d also look a little nicer if each shelf didn’t have a crack going through it.
