Upgrade your home theater experience with the Polk Audio Signa S4, a powerful yet compact Dolby Atmos-certified 3.1.2 sound bar system designed to immerse you in rich, 360-degree surround sound. Featuring an advanced seven-driver array and dedicated up-firing height speakers, the Signa S4 brings lifelike cinematic audio to your living room. Whether it’s the latest blockbuster, an intense gaming session, or your favorite music, this sound bar ensures breathtaking clarity and depth.
Polk’s patented VoiceAdjust™ technology enhances dialogue, allowing you to hear every word clearly without raising the overall volume. This is especially useful for movies and TV shows where speech can sometimes get lost in the background. Plus, preset sound modes—including Movie, Music, and Night Mode—let you customize the listening experience. Night Mode lowers bass and amplifies dialogue, making it perfect for late-night viewing without disturbing others.
The included wireless subwoofer delivers deep, effortless bass, adding impact to every scene. Polk’s BassAdjust™ technology ensures a seamless blend between the sound bar and subwoofer, providing a balanced and immersive sound experience. The subwoofer connects automatically and can be placed anywhere in the room for maximum flexibility.
Setting up the Signa S4 is effortless with its universal TV compatibility and multiple input options, including HDMI eARC, optical, and AUX. It pairs quickly with your TV remote and supports Bluetooth streaming, allowing you to play music from your smartphone, tablet, or other devices. With its low-profile, wall-mountable design, the Signa S4 integrates seamlessly into any home entertainment setup.
