ESB Audio 3.10D4 car subwoofer

This ESB subwoofer is a precision speaker designed to deliver very high-quality sub-bass frequency performance in a car.

The included technical data sheet contains specifications and two recommended enclosures: one is a sealed enclosure; the other is a ported model.

Enclosure recommendation

The subwoofer is suitable for both sealed and ported enclosures. A sealed enclosure is a better option if space is limited, while a bass reflex enclosure produces 3 dB more output with the same power. More detailed enclosure recommendations can be found in the included data sheet.
