This 2 inch 2 ohm Midrange driver, with 0.8 inch voice coil copper 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.
- 2”, Steel Frame
- 0.8” CCAW Voice Coil, Kapton Former
- PULP Diaphragm and Coating Black Dust Cap
- Dual Neodymium Magnet Motor System
- Low Distortion (<3%)
