What did they say? You won't be asking with our patented VoiceAdjust™ technology that delivers crystal clear dialogue.
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.
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.
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.
Signa S4’s powerful wireless subwoofer provides the deep, effortless bass that Polk is famous for, at a loudness level that is surprising for its size. The subwoofer connects automatically on start-up and can be conveniently placed nearly anywhere in the room. Put it up front or in the corner for maximum impact or try behind the couch and feel the rumble.
Set up is easy: one simple connection via the included HDMI or optical cable (or aux-in for older TVs) ensures the ultimate listening experience with virtually any TV—even the latest 8K Ultra-HD TVs. For added convenience, Signa S4 is pre-programmed to work with most TV remotes out of the box and it quickly pairs to your mobile device via Bluetooth to stream your favourite 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.
The Signa S4 Dolby Atmos 3.1.2 sound bar with wireless subwoofer delivers powerful, crystal clear, cinematic 3D surround sound—at an unbeatable value.
50 years, hundreds of thousands of speakers, and countless awards later, we are still focused on our mission of giving you the absolute best sound for your money. Great Sound for All.
