The Polk Signa S4 is good all-round performer that produces a decent front soundstage with a solid foundation of bass. The overall delivery is smooth, with a clean treble and well-defined...
The Polk Audio Signa S4 is a 3.1.2 setup that offers a more affordable alternative to other Atmos bars on the market. Its Atmos performance is comparable to similarly-priced bars like the Sonos Beam (Gen 2), but it doesn't offer the same immersive sound as more premium setups.
Overall, the Polk Audio Signa S4 really impressed me. Considering this soundbar + subwoofer combination is under $400, this is a stellar performance, certainly worthy of its 4-star rating.
Polk's soundbars have consistently been great with music, and the Signa 4 certainly carries the torch for musical replay. And it's just as talented when it comes to films. Whether you're...
The Signa S4 is a straightforward soundbar with pleasing sound quality and Dolby Atmos support – but it’s not without its drawbacks.
Review: Polk Signa S4 This Dolby Atmos-enabled soundbar and wireless subwoofer combo is the audio upgrade you’re looking for—at a reasonable price.
Combined with the wireless subwoofer with a 5.9-inch woofer, it forms a true Dolby Atmos 3.1.2 channel Soundbar system. The Soundbar itself has a longer design, but its 60mm height is low and thin enough not to block the TV screen. In addition, it supports wall mounting and is flexible in placement. Connection and setup are also very convenient.
Most budget soundbars promise big sound but deliver disappointing results, yet the Polk Audio Signa S4 breaks this frustrating pattern by packing genuine audio punch into an affordable package that transforms your TV experience.
Therefore, I was intrigued at the prospect of reviewing Polk's new Signa S4 soundbar. I'm a big Atmos fan for the format's convincing staging, and at $399, the S4 is among the least expensive certified Atmos bars you can get.
But Polk’s big achievements with the Signa S4 are its simplicity of setup and its ability to reproduce crystal clear voice and dialogue — something that often gets overlooked.
