Professional sources highlight the SA-SW5 as a premium, tightly integrated component of Sony's soundbar ecosystem, emphasizing its proprietary S-Master amplification, Sigma Magnetic Circuit, and wireless 5.0 GHz RF connectivity. Reviewers note that these technologies aim to deliver powerful, low-distortion bass while maintaining a compact, cable-free design, positioning the subwoofer as a high-end add-on rather than a universal aftermarket upgrade.
Everyday owners love the deep, powerful bass output from 300 W amplification and the wireless convenience, but many note the sub's limited compatibility with non-Sony equipment and the absence of phase-adjustment.
Professional reviewers highlight the Sub 4's deep 25 Hz low-frequency response with force-canceling dual woofers, automatic Trueplay room-acoustic tuning and app-adjustable EQ deliver optimized bass for any space. Flexible placement allows vertical or horizontal orientation, even under furniture, for hidden installs.
