Polk Audio Signa S2 Sound Bar with Wireless Subwoofer - Slim TV

Our review of the Polk Audio Signa S2 finds it best suited for consumers who want a quick, affordable home theater upgrade without fuss. The single biggest reason to buy is the combination of a slim 2in sound bar, an included wireless subwoofer and Polk's VoiceAdjust technology, which together deliver clearer dialogue and noticeably fuller low end than most built-in TV speakers. Setup is simple with the included HDMI and optical cables, and Bluetooth streaming makes it a practical everyday audio solution.

Key Features

• Ultra-slim design: At just over 2in tall the bar fits neatly in front of most TVs or mounts on the wall without blocking the bottom screen edge or IR sensor.
• Wireless subwoofer: An included wireless subwoofer supplies deep bass impact for movies and music without extra wiring across the room.
• VoiceAdjust technology: Polk's exclusive VoiceAdjust enhances dialogue clarity so speech is easier to follow in TV shows and films.
• Multiple inputs: HDMI ARC, optical and AUX connections let you plug the bar into 4K and HD TVs or other audio sources quickly using the supplied cables.
• Bluetooth streaming: Stream music wirelessly from phones or tablets to play Pandora, Spotify and other apps without connecting a player each time.

Who It's For

The Signa S2 is ideal for apartment dwellers, smaller living rooms and anyone replacing weak built-in TV speakers who wants easy setup and a tidy footprint. Its slim height and wall-mount compatibility make it a good fit where space is limited and a wireless subwoofer reduces cable clutter.

Shoppers needing full multi-channel surround processing, advanced room calibration or very large-room output should look elsewhere; the Signa S2 is tuned for clarity and value rather than audiophile-level power or complex custom installations.
