This 2 inch 4 ohm Fullrange driver, with 0.8 inch voice coil ccaw wire, Kapton former, paper cone and damped rubber surround. It contains dual Neodymium magnet motor system which provides maximum flux in a compact package. The Kapton former and basket under spider are vented holes so as to reduce air compression effects and aid cooling of the motor under high excursion conditions.
