ESB Audio 3.WB6 — 6.5"/165 mm Active Ported Subwoofer | HF Audio

3000 Series compact active powered subwoofer. Plug-and-play bass, no separate amp needed.

Built for the Passionate. Engineered for the Road. The ESB 3.WB6 is a self-powered active subwoofer — a 6.5" driver in a tuned ported enclosure with an integrated amplifier. Plug the RCA or high-level inputs into your source and you have Italian-engineered bass without a separate amplifier, external enclosure, or complex wiring. This is the simplest bass upgrade in the ESB catalog. The active format makes the 3.WB6 the right choice for OEM integration projects, secondary vehicles, and anyone who wants meaningful bass improvement without a full system build. The integrated amp is matched to the driver and enclosure — no guessing at amplifier power or box tuning. Compact enough for underseat and cargo area placement. Connect to any head unit, factory or aftermarket. A complete self-contained Italian bass solution.
