This 3.25 inch 6 ohm Fullrange driver, with 0.8 inch voice coil copper clad Aluminum wire, TiL former, damping glue coated glass fiber cone and rubber surround. It contains copper shorting cap on pole piece, which reduces coil inductance, thus providing both extended frequency response performance and reduced distortion. The TiL former, bottom plate and basket under damper are all vented hole so as to reduce air compression effects and aid cooling of the motor under high excursion conditions.
