SPEC SHEET

This 12inch 8ohm Woofer driver features a strong ferrite magnet with bump bottom plate and long-throw voice coil, which has high excursion. The distortion can be decreased by AL short circuit ring at low frequency, and the semi-pressed paper cone will 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. The cast aluminum frame can provide strong support to ensure no resonance at low frequency.
