SPEC SHEET

This 3 inch 8 ohm Fullrange driver, with 0.8 inch voice coil copper clad Aluminum wire, Aluminum former, damping glue coated glass fiber cone and NBR rubber surround. It contains copper shorting cap on pole piece, which reduces coil inductance, thus providing both extended frequency response performance and reduce distortion. Whizzer cone in center can increase HF output. The Aluminum former, bottom plate and basket under spider are all vented hole so as to reduce air compression effects and aid cooling of the motor under high excursion conditions.
