This 1.5 inch 4 ohm compact driver, with 0.6 inch voice coil copper clad Aluminum wire, kapton former, paper cone and rubber surround. It contains a powerful Neodymium magnet motor system, bumped bottom plate which can offer high power handling property. The tetoron center cap can smooth the response curve at high frequency. The kapton former and basket under spider are all vented holes so as to reduce air compression effects and aid cooling of the motor under high excursion conditions.
