Enjoy the latest blockbuster releases, immersive music, and your favourite TV shows in the amazing 3D sound provided by Dolby Atmos and the Polk Audio Signa S4. Featuring an advanced seven-driver array and a powerful wireless subwoofer, this 3.1.2 sound bar system delivers a lifelike Atmos listening experience with a huge soundstage, effortless bass, and crystal-clear dialogue.

Key Features:

Dolby Atmos Certified 3.1.2 System: Dedicated up-firing speakers support Atmos height channels to immerse you in 360 degrees of surround sound. Standard audio can also be up-mixed to create a virtualized Atmos experience.
Polk VoiceAdjust™ Technology: Patented speech-clarifying technology pairs with a dedicated center channel, allowing you to raise the volume of voices for clear, easy-to-understand dialogue without altering the rest of the soundtrack.
Powerful Wireless Subwoofer: Provides deep, effortless bass for maximum impact. Connects automatically on start-up and can be conveniently placed nearly anywhere in your listening room.
Customisable Sound Modes: One-button presets optimize the sound bar for movies and music, while Night Mode lowers the bass and increases VoiceAdjust™ so you can enjoy late-night viewing without disturbing others.
