The DB4S is the smaller of Bowers & Wilkins' two-model DB Series subwoofer line, built around a single variable-thickness Aerofoil-cone driver in a sealed, acoustic-suspension cabinet driven by a 1,000-watt Class D Hypex amplifier (source: [Bowers & Wilkins](https://www.bowerswilkins.com/on/demandware.static/-/Library-Sites-bowers_europe_shared/default/dw2e593228/downloads/db4s-info-sheet.pdf), [Crutchfield](https://www.crutchfield.com/p_749DB4SGB/Bowers-Wilkins-DB4S-Gloss-Black.html)).
