Hear Every Word with VoiceAdjust

To make sure you hear every word, Polk created the VoiceAdjust. With the help of this unique technology and the dedicated center channel on the Signa S-4 by Polk, you are able to increase the volume of just the voices, making them understandable and clear, while leaving the rest of the soundtrack alone.

Establishes in Seconds

For the best sound quality on any TV, including the most recent 8K Ultra-HD TVs, simply connect the provided HDMI or optical cable. The Signa S 4 can easily pair with your mobile device over Bluetooth to play your favorite music, and it is pre-programmed to work with the majority of TV remote controls. Last but not least, the Polk S4 Soundbar with subwoofer low-profile design allows for versatile positioning and won't obstruct your TV or remote.

Effortless Bass with a Wireless Subwoofer

Five Decades of Engineering the Perfect Home Theater Sound

The speaker's experts at Polk created the S4 Signa in our Acoustic Research and Development facility outside of Baltimore, Maryland. Signa S4 will provide the booming, crystalline clear, dramatic surround sound experience you've always dreamed of in your home—but at a price, you could only fathom. We've drawn on more than 50 years of American hi-fi loudspeaker engineering to make this possible.

True Dolby Atmos Sound Bar System

The Dolby Atmos Certified Signa Soundbar S4 surrounds you in sound from every angle. Regular surround sound and Dolby Atmos Certified sound vary in that the latter offers a true 3D audio experience with the extra playing of height channels. Signa S4 offers an extraordinarily realistic sound environment, with everything from music's additional atmosphere to special effects soaring overhead.

Adaptable Sound: Music, Movie, and Night Modes

With Night Mode, you can hear every word without turning up the master volume by just pressing a button that simultaneously lowers the bass and raises Voice Adjust. Additionally, one-button preset sound settings on the S 4 Signa improve the audio for watching movies and listening to music. Polk has been a leader in high-fidelity engineering for 50 years, and the Signa S4 is made to perform and last.
