ESB 3.10D4

Your ESB subwoofer is a precision loudspeaker which has been designed to produce very high-quality sub-bass frequency performance in your car. For maximixe the performance of your speaker we highly recommend to use a dedicated enclosure. Inside the data sheet you will find specifications and two recommended enclosures: one is a sealed enclosure, the other is a ported design. Both types of enclosures will give you excellent sound quality and low-frequency extension. The sealed enclosure is a better choice if space is extremely tight, but the ported enclosure will produce 3dB more output at the same power if you have the extra space to work with. - Non-pressed paper cone with long travel foam surround. - Dual 44.7 Oz ferrite magnet, 2”/50 mm voice coil. - Steel basket with anti-resonant painting.
