SPEC SHEET

This 2 inch 4 ohm Fullrange driver, with 0.8 inch voice coil ccaw wire, Kapton former, paper cone and damped NBR 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.
