POLK SIGNA S4 True Dolby Atmos 3.1.2 Sound Bar With Wireless Subwoofer EARC and Bluetooth
Elevate your home entertainment with the Polk Audio Signa S4, a cutting-edge Polk sound bar system that delivers true Dolby Atmos 3.1.2 surround sound. Designed to bring movies, music, and TV shows to life, the soundbar Polk combines powerful performance with effortless usability for an immersive listening experience that fits any modern living room.
Immersive 3D Audio with Dolby Atmos
Step into a world of cinematic sound with the Polk Audio Signa S4, featuring a Dolby Atmos certified 3.1.2-channel configuration. With upward-firing drivers that create a stunning overhead effect and virtual height channels, this Polk sound bar places you right in the heart of the action—even when watching non-Atmos content, thanks to intelligent up-mixing.
Powerful Wireless Subwoofer for Deep Bass
Experience rich, room-filling bass without the clutter of cables. The Signa S4’s wireless subwoofer connects automatically for easy placement and impactful low-end response. Whether you tuck it in a corner or behind your couch, it delivers the signature low-end punch that Polk Audio is renowned for.
Hear Every Word with Polk VoiceAdjust™
No more struggling to hear dialogue. Polk’s patented VoiceAdjust™ technology ensures vocals are crystal clear, even during intense action scenes or heavy bass moments. Combined with a dedicated center channel, it isolates speech so you can understand every word—without adjusting the overall volume.
Custom Sound Modes: Movie, Music & Night
Tailor your audio to suit your mood with one-button presets. Enjoy cinema-quality sound in Movie Mode, rich detail for your playlists in Music Mode, or switch to Night Mode, which lowers the bass and boosts dialogue for late-night viewing without disturbing others.
Seamless Setup with HDMI eARC & More
Connecting the Polk Signa S4 is a breeze. Use the included HDMI eARC, optical, or aux-in cables to link it to virtually any TV—including 4K and 8K models. With eARC, you'll enjoy high-definition audio formats like Dolby TrueHD and DTS-HD Master Audio using just one cable.
Stream Music with Bluetooth
Wirelessly stream your favourite tunes from your smartphone or tablet via Bluetooth. Whether it's a party playlist or your favourite podcast, enjoy the flexibility of wireless audio on demand.
Sleek, Low-Profile Design
Crafted with a modern, minimalist aesthetic, the Polk Signa S4 won’t block your screen or remote sensor. Mount it on a wall or place it neatly under your TV—either way, it enhances your space while delivering big sound.
