Built for the install, not the spec sheet
Built for the Passionate. Engineered for the Road. The ESB 3.WB8 B is the iron bar grille variant of the 3.WB8 active subwoofer — same self-powered 8"/200 mm driver in a tuned ported enclosure with an integrated 600W Class D amplifier, now with a heavy-duty iron bar grille for exposed installations where driver protection is a priority.
The 3.WB8 platform uses a breakthrough construction approach: a 0.25Ω ultra-low impedance driver matched to an amplifier without a switching power supply stage — delivering less noise, higher efficiency, and more power in a compact 15 cm deep enclosure. Plug-and-play RCA or high-level inputs, no external amplifier required.
The iron bar grille version is the choice for trunk installations where the subwoofer is visible or exposed to handling. Same performance as the 3.WB8, with added driver protection and an aggressive industrial aesthetic that complements performance builds.
