## Description

Polk Audio Signa S4D for room-filling sound with a sleek profile The Polk Signa S4D soundbar brings Dolby Atmos 3.1.2 audio into your home in a sleek, sophisticated package. Designed for immersive 360° sound, the seven-speaker array complete with dedicated height speakers delivers a multidimensional listening experience. Whether you're watching the latest blockbuster or gaming with friends, you'll feel completely surrounded by sound. With a wireless subwoofer and patented VoiceAdjust technology, the Signa S4D delivers deep bass and crystal clear dialogue without the need to continuously increase overall volume. Thanks to its simple HDMI eARC, optical and aux connections, it is compatible with virtually any installation, while Bluetooth lets you stream music directly from your favorite devices. Night mode lowers bass and improves speech for quiet, nighttime playback. The exclusive online finish of the Signa S4D adds an aesthetic distinction to your home audio system. Designed in Baltimore, Maryland, each Polk product reflects a heritage of audio excellence. Backed by over 50 years of innovation, the S4D is more than a sound bar, it's a hi-fi sound system built for today's smart home entertainment systems.

Review: Great clear sound with strong enough bass. The feature to increase the volume of voices is great with so many poorly mixed movies with ultra loud music and effects and not loud enough dialog. The ARC connection is great for sound quality and also nice that it turns on an off with my TV and the TV remote volume control adjusts the sound bar. Room filling sound for small package. Very easy to setup
Review: System was plug and play. Provides an immersive sound experience at an affordable price point. In my opinion, Polk Audio is underrated. TV broadcasts sound so much better with this Polk Audio system than the TV's internal speakers. I am very pleased with its performance.

### ⭐⭐ Review
*by S***N on 11 February 2026*

I picked this based on a lot of research. For the price it’s not worth it. The sound bar doesn’t offer a full range and without the sub it’s almost all high with no filling mid tones. I don’t hear voice quite as well as I used to, and there are a lot of options usually accessible on the remote, but they end up being all voice or all base. Very disappointing for a sound bar that cost almost as much as my TV.
