REVIEW: Polk Signa S4 - The budget soundbar that aims above its rank

Polk's Signa S4 soundbar is a budget-friendly marvel, offering Dolby Atmos support and a wireless subwoofer for an unbeatable price. It delivers a surprisingly expansive soundstage and deep bass, though the mid-bass resonance could be more refined. Its build quality isn't premium, but it gets the job done. The soundbar excels in producing a wide sound image, making it an excellent choice for both music and movies. While it lacks the sophistication of high-end systems, it punches well above its weight class, making it a standout option for those seeking value without sacrificing too much on audio performance.

The Polk Audio Signa S4 soundbar hits the sweet spot for budget-conscious Dolby Atmos seekers, delivering punchy sound performance in both movies and music. Its physical upfiring speakers provide a genuine height experience unlike many competitors' simulated effects.

The Polk Audio Signa S4 soundbar offers a decent 3.1.2 setup that's easy on the wallet, featuring Dolby Atmos support and a V-shaped sound profile that gives music a bit of extra kick in the bass and treble. Its dialogue clarity and enhancements are noteworthy, making TV shows and podcasts a breeze. However, it misses the mark on delivering that deep thump in low-bass, crucial for action movies and bass-heavy tracks, and its surround sound isn't particularly immersive. While it's a good option for budget-conscious buyers, those seeking richer bass might need to look elsewhere.
