Consumer Benefits

Five Decades of Engineering for the Perfect Home Theater Sound
Signa S4 was designed in our Acoustic Research and Development center outside Baltimore, MD by the speaker experts at Polk. We’ve leveraged over 50 years of American hi-fi loudspeaker engineering so Signa S4 will deliver the surround sound experience you’ve always dreamed of in your home—but at a value you could never imagine.

Dolby Atmos Certified 3.1.2 Sound Bar System
Enjoy the latest blockbuster releases, immersive music, and your favorite TV shows in the amazing 3D sound provided by Dolby Atmos* and the Signa S4. Its advanced seven-driver array and wireless subwoofer deliver a lifelike Atmos listening experience with a huge soundstage and effortless bass. With Signa S4, you’ll hear sounds flying overhead courtesy of up-firing speakers that support Atmos height channels, and any non-Atmos content you watch can also be enjoyed in a virtual Atmos experience. *Requires HDMI eARC connection.
