Lifelike Movie 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
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.
