SPEC SHEET

A double suspension(patented) driver, with elimination of the limits from traditional single suspension driver, resulted in more diverse and slim design. This 2 inch 3 ohm compact driver features dual rubber surround and black anodized Aluminum cone. The voice coil former and pole piece are vented hole so as to reduce air compression under high excursion conditions.
