The Bose Bass Module 500. The Sony measures 15.75 in high, 15.4 in wide and 13.88 in deep, so check your floor space.

Can I add a second subwoofer?

Do both have app control?

Sony BRAVIA Theater Sub 9 vs Bose Bass Module 500

The Sony BRAVIA Theater Sub 9 is the stronger subwoofer on paper: dual opposing 200 mm drivers, 600 W, and a sealed cabinet for tighter bass. The Bose Bass Module 500 is the smaller, simpler add-on for a Bose soundbar system. At $598 at Walmart as of November 7, 2026, the Sony costs more than the Bose typically does, so buy the Bose only if you already own a compatible Bose soundbar and want a compact match.
