Expert consensus

The Polk Audio Signa S4 is an affordable and versatile soundbar that offers clear dialogue, a slightly V-shaped sound profile, and supports Dolby Atmos technology, making it suitable for small to medium-sized rooms for watching movies, TV shows, and listening to music.

The Polk Audio Signa S4 is a versatile and affordable soundbar that offers clear and accurate dialogue with balanced mids and a discrete center channel. It has a slightly V-shaped sound profile that adds extra punch in the bass and brightness in the treble, making it suitable for music listening.

The soundbar supports Dolby Atmos technology, which creates a more immersive sound experience with height channels, making it suitable for larger rooms with high ceilings. However, the lack of low-bass takes away from the immersive feeling in action movies, and its surround sound performance isn't the most impressive.

It is compatible with any TV, including the latest 8K Ultra-HD TVs, and any device that has Bluetooth connectivity, as well as TVs with ARC support.

The Polk Audio Signa S4 has a sleek and minimalist design that fits well with most home decor styles, and its black color makes it easy to blend into any room setup.

Sound quality

The Polk Audio Signa S4 soundbar has clear dialogue and supports Dolby Atmos technology, but lacks low-bass and impressive surround sound performance.

The Polk Audio Signa S4 soundbar has clear and accurate dialogue with balanced mids and a discrete center channel that anchors voices to a pinpoint location in the soundstage. It has a slightly V-shaped sound profile that adds extra punch in the bass and brightness in the treble, making it suitable for music listening.

The soundbar supports Dolby Atmos technology, which creates a more immersive sound experience with height channels, making it suitable for larger rooms with high ceilings.
