Overview

Polk Signa S4 Dolby Atmos 3.1.2 Sound Bar with Wireless Subwoofer - Black

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

Features:

Advanced 3.1.2 Sound Bar
Enjoy the latest blockbuster releases, immersive music, and your favourite TV shows in the amazing 3D sound provided by Dolby Atmos and the Signa S4. Its advanced seven-driver array and wireless subwoofer deliver a lifelike Atmos listening experience with a huge soundstage and effortless bass. With Signa S4, you'll hear sounds flying overhead courtesy of up-firing speakers that support Atmos height channels, and any non-Atmos content you watch can also be enjoyed in a virtual Atmos experience.

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.

Customizable Sound - Music, Movie, Night Modes
Late night binge-watching session? Don't worry about waking your family or neighbors. With Night Mode, one button lowers the bass while increasing VoiceAdjust so you can hear every word, without raising the master volume. Plus, one-button, preset sound modes optimize the Signa S4 so you can have the best sonic experience for movie watching and music listening.

Deep Effortless Bass
Signa S4's powerful wireless subwoofer provides the deep, effortless bass that Polk is famous for, at loudness levels that are surprising for its size. Polk's exclusive BassAdjust mode controls bass on both the sound bar and sub ensuring seamless blending. The subwoofer connects automatically on start-up and can be conveniently placed nearly anywhere in the room. Put it up front for maximum impact or try behind the couch to feel the rumble.

Rated 5 out of 5 by from HDMI or optical I purchased the Signa S4 yesterday and believe me it sounds really great. Although I have a question, Got little confused while reading the Guide. Connecting through a HDMI cable is better or optical?

Rated 5 out of 5 by from Great sound Sounds great, easy to connect to my LGTv. Love that you can change it from music to movie and can increase the dialogue volume.

Rated 5 out of 5 by from Not the most expensive and great sound I replaced my previous Polk sound bar with the S4. What a world of difference between the two! The spatial sound that comes from this bar is amazing. As others mentioned the bass is limited, but it works well enough for me.

Rated 5 out of 5 by from Setup does NOT get easier than this. I am super impressed with my first soundbar and couldn't be happier with this Polk model. It was super easy to set up. The Bar required just a power cable and an HDMI (look for the HDMI port on your TV that says (ARC)). Amazingly, the woofer only required a power cable. After that, everything connected on its own. Power up your TV and the entire system powers up. No additional setup necessary. The sound system automatically powers up when your TV does.

Rated 5 out of 5 by from I can understand what is said. I have been having a lot of trouble hearing and understanding talk vocals on my TV for many years. I have often blown my forgiving wife away with loud volumes to be able to maybe, understand what is being said. My new Signa S4 has changed all of that. I was truly amazed at how clearly I can hear and understand what is being said. I am still learning the ins and outs of settings for particular shows but, I can't say thank you enough for making my TV viewing experience a pleasure once again.

Rated 5 out of 5 by from Best soundbar I've ever owned This by far is the best soundbar I've ever owned, I'd been researching soundbars when I seen this ad for the Polk Signa S4, I have to tell ya, it looked and sounded pretty amazing I wanted a soundbar for my Sony Bravia 75 inch TV, so I ordered it off that ad on Instagram it got here pretty fast, so I started to set it up, hooked it in to the HDMI, and it emediatly paired to TV the sound came on, and it scared me it was loud and it sounded dam good I was so impressed and happy, I highly recommend this soundbar
