Polk Audio Signa S4
Score: 79/100
Klipsch Flexus CORE 210
Score: 77/100Rankings
The Polk Signa S4 is a slim Dolby Atmos sound bar with a powerful 410 W output, VoiceAdjust dialogue enhancement, and a wireless subwoofer, delivering immersive audio for small to medium rooms. Its drawbacks include the lack of a standard HDMI input and occasional Bluetooth hiccups, which may affect connectivity flexibility. Best suited for budget-conscious viewers with 40-55" TVs who prioritize immersive sound and dialogue clarity.
The Klipsch Flexus CORE 210 soundbar system offers 185 W RMS power, dedicated Atmos elevation drivers, and a wireless 10" subwoofer for an engaging home-theater experience. Its energetic signature and lack of built-in rear speakers may limit appeal to listeners seeking a neutral sound or a complete surround setup. Best for medium-sized rooms where a sleek, powerful bar with Atmos is desired.

Professional reviewers commend the Signa S4 for its impressive bass output, clear dialogue thanks to VoiceAdjust, and effective Atmos height effects, noting it offers strong value in the entry-level Atmos segment. However, they criticize the missing standard HDMI input and the need for careful bass balancing, suggesting it's best suited for users who prioritize sound impact over extensive connectivity.
Everyday users love the easy wireless sub setup, the room-shaking bass, and the clear speech reproduction, especially for movies and sports. Common complaints revolve around the sub's heft, occasional Bluetooth hiccups, and the inability to connect multiple HDMI sources, with some noting the bass can dominate mids if not tuned.

“powerful bass that rumbles behind couch”
Professional reviewers commend the Flexus CORE 210 for its cinematic dynamics, energetic Klipsch signature, and immersive Atmos height channels that create a much more immersive bubble than basic bars, while also noting its clean performance at high volumes, best-in-class bass, and straightforward setup via HDMI eARC, wireless sub and app control.
Everyday users consistently praise the deep, punchy bass and the immersive Atmos experience for movies and gaming, as well as the ease of wireless Bluetooth streaming, but they also report that the bold, non-neutral sound can dominate quieter scenes and that the lack of built-in rear speakers limits full surround immersion.
