What customers say
Customers overwhelmingly praise the Polk Audio Signa S4 for delivering exceptional value, especially for movie watching. The standout feature is its surprisingly immersive Dolby Atmos performance, creating a noticeable sense of overhead sound for its price point. Dialogue clarity is another major benefit, as VoiceAdjust technology effectively sharpens speech, making content easy to follow. Setup is consistently reported as quick and straightforward. Furthermore, the wireless subwoofer provides robust, satisfying bass that complements the system well. While some users note the remote feels less premium and prefer a full display, these minor points do not detract from the soundbar's core strength: providing a significant, cinematic audio upgrade that offers excellent overall value.
Know before you buy
Yes. The soundbar features dedicated up-firing speakers that bounce sound off your ceiling to create a 3D audio experience, providing the height channels necessary for true Dolby Atmos playback.
At only 2.36 inches tall, the Signa S4 is designed to sit discreetly below most modern televisions without obstructing the screen or the TV's remote sensor.
Polk’s VoiceAdjust technology allows you to independently control the volume level of the center channel. This helps isolate and boost dialogue, making voices clearer even when background music or action sequences are loud.
The subwoofer connects to the soundbar wirelessly, which makes placement in your room much easier. However, it still requires its own connection to a wall power outlet to function.
Yes, the Signa S4 includes built-in Bluetooth 5.0, allowing you to wirelessly stream music, podcasts, or other audio directly from your smartphone or tablet.
The eARC (Enhanced Audio Return Channel) connection allows for higher-quality, uncompressed audio transmission from your TV to the soundbar. It also enables you to control the soundbar's volume using your existing TV remote.
