Enjoy deep bass with the included wireless subwoofer. Plus, stream your favorite music through Bluetooth. Includes HDMI cable for quick and easy setup.

Performance-Tuned Surround Sound

Performance tuned driver array and Dolby Digital 5.1 decoding create incredible room-filling surround sound from a compact low-profile soundbar and wireless subwoofer.

Universal Compatibility

Works with 4K and HD TVs — HDMI cable included. Watch your favorite shows with exceptional contrast and clarity.

Easy Setup, Low-Profile Design

Polk VoiceAdjust™ Technology

Customize the voice levels in the sound bar to reproduce clear, crisp dialogue and never miss a single word of your favorite movie, TV show or sporting event.

Wireless Music Streaming

Bluetooth technology lets you stream music directly from your smartphone, tablet or other compatible device.

HDMI Audio Return Channel (ARC)

Send audio from smart TV built-in apps and sources connected directly to the TV to the Signa S2 via a single HDMI cable. Also allows for control of the Signa S2 volume via the TV remote control (requires CEC enabled TV).

Movie and Music Modes

One button preset EQ settings for Movies and Music optimize the sound bar and subwoofer to ensure the clearest dialogue, immersive surround sound and deep bass impact for the best audio and home theater experience.

Night Mode

Hear it all without disturbing others in and around your home — access Night Mode at the push of a button to lower the bass and increase Voice Adjust for clear dialogue, all without raising the master volume.
