Critic Reviews

Polk Signa S3 review: Feature-packed soundbar excels with music, too - CNET

cnet.com

The Polk Signa S3 soundbar delivers solid musical performance with its powerful subwoofer and Chromecast streaming, making it a great choice for music lovers. While it excels in music playback with exciting, detailed sound and punchy bass, it falls short for movie enthusiasts compared to rivals like the Vizio V21, which offers better virtual surround sound. The Signa S3's design is functional but lacks flair, and it's missing some features like DTS Virtual:X processing and a built-in voice assistant. Overall, it's a strong value for music-focused users, but film buffs might find it less impressive.

Polk Audio Signa S3 Review | PCMag

pcmag.com

The Polk Audio Signa S3 delivers impressive bang for your buck, offering a robust 2.1 audio experience with deep bass and crisp highs. Its wireless subwoofer and Voice Adjust mode enhance both music and dialogue, while Chromecast and Google Assistant support add modern convenience. However, the system lacks an EQ for fine-tuning and could use better visual indicators for its audio modes. Despite these minor setbacks, the Signa S3 is a powerful and versatile soundbar-subwoofer combo that offers great value at $249, making it a strong contender in its price range.

Polk Audio Signa S3 Review | Tested & Rated

techgearlab.com

The Polk Audio Signa S3 soundbar impresses with its voice enhancement features and versatile connectivity options, including Chromecast and Bluetooth. While it's a step up from many TV speakers, the sound quality falls short compared to pricier models, and its large subwoofer may be cumbersome for some setups. Setup can be frustrating due to unclear instructions, especially for WiFi. Though it offers a good range of features for the price, audiophiles might prefer to invest a bit more for superior sound quality.
