Performance-Tuned Surround Sound

Performance-tuned 2.1 channel driver array and Dolby Digital 5.1 decoding create incredible room-filling virtual surround sound, from a compact low-profile soundbar and wireless subwoofer.

Wireless Subwoofer

Paired with the soundbar, the included wireless subwoofer reproduces deep bass impact you can feel for all your home theatre and music needs. Being wireless the subwoofer can be placed around the room with no messy speaker cables laying around! (subwoofer requires power cable)


Like it's predecessor, the S2, the Signa S3 includes HDMI-ARC (Audio Return Channel) functionality making it easy to connect to almost any modern TV. Simply plug your source device (Blu-ray player, Set-top Box etc) into your TV as normal, then use a compatible HDMI-ARC output on your TV to connect to the Signa S3 soundbar.

Polk Signa S3 review: Feature-packed soundbar excels with music, too

"Soundbars aren't just for watching TV and movies. They can do music too, and models like the Polk Signa S3 prove that musical sound from a bar doesn't have to cost a fortune. The Signa's superlative audio performance is anchored by a potent subwoofer that helps bolster the bottom end of both tricky soundtracks and bass-heavy music."
