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.

Customisable 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.

Sets Up In Seconds

Set up is easy: simply connect the included HDMI or optical cable (or aux-in on 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. Signa S4’s low-profile design won’t block your TV or your remote. Signa S4 can be wall-mounted for flexible placement.

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.

Questions

Our Polk s4 is 9 months old and has worked flawlessly for that time. Recently it stopped producing sound. I have tried every reset, disconnected and replaced HDMI cable, performed power disconnect and nothing seems to work. I’m hoping for some assistance.

Do you have to have the subwoofer be wireless? It looks like there is a cable port in the back of it. If I prefer, can I connect it directly to the soundbar with the appropriate cable?

Asked by: Penn
Hello, the provided wireless subwoofer for the Polk Audio S4 cannot be hardwired to the soundbar. It is wireless only.

Can bar be placed above a wall hmou.ted tv

Asked by: Raja5555
Hello, the bar can be placed above the television and mounted to the TV. Please note that most TV soundbar mounts are designed for the Bar to be placed below the Television. The S4 does provide keyholes for mounting.

I have a Sony XBR-65X900E. The manual indicates one of the HDMI ports is HDMI(ARC). The Signa S4 specifications indicate e-ARC input. Will this system work well with my TV using an HDMI(ARC) input?.

Asked by: Todd B
Hello, Yes. HDMI ARC suuports an audio feed from anything you watch on your TV. eARC would also allow for more advanced audio encoding (such as Dolby Atmos) to be transfered with content which carries it, but without eARC you will still have a very good quality audio feed with an HDMI cable.

If I input one or more analogue inputs into my TV, will all audio sources be output to the sound bar via the digital optical input?

Asked by: J Rokich
In most cases, the TV will output all connected audio out through the optical audio output. Please confirm with your TV manufacturer.

The subwoofer is emitting an echo sound on voices. I've moved the subwoofer closer and further away from the bar and used the different voice settings, the condition exists in all setups I've used. Is the sub blown or any ideas how to address?

Asked by: flynny19
Hello, the wireless subwoofer will typically sound best when placed close to the soundbar. For increased bass performance, corner placement is recommended. Regarding an echo, placing the subwoofer close to the bar and decreasing the bass should correct any echo. If further assistance is required, please get in touch with support by visiting https://support.polkaudio.com/.
