This 12 inch 8 ohm Woofer driver features a strong ferrite magnet motor system with bump bottom plate and long throw
voice coil, which has high excursion. The distortion can be decreased by Aluminum short circuit ring at
low frequency, the semi-pressed paper cone uses a new mixed material of 40% pulp and 60% carbon
fiber to make the sound stronger and sonorous. Beyond that, the wonderful collocation of foamed rubber
surrounding, CCAW and short circuit ring can provide high SPL and extended high frequency.
