This ESB subwoofer is a precision loudspeaker that was designed to produce very high-quality sub-bass frequency performance in a car. To maximize the performance of this subwoofer we highly recommend using a dedicated enclosure. Inside the included datasheet are specifications and two recommended enclosures: one is a sealed enclosure; the other is a ported design. Both types of enclosures will give excellent sound quality and low-frequency extension. The sealed enclosure is a better choice if space is extremely tight, while the ported enclosure will produce 3dB more output with the same power if there is extra space to work with.
- Non-pressed paper cone with long throw foam surround.
- Dual 44.7 Oz ferrite magnet, 2”/50 mm voice coil.
- Steel basket with anti-resonant painting.
