Peak Momentary Power Output：2400 Watts RMS Power:800 Watts Max Power:1600 Watts Sensitivity:79.8dB 1W/1m Impedance:Dual 2 ohm Resonance frequency:33.40 Hz Qms:4.143 Qes:0.927 Qts:0.757 Linear cone excursion:+/- 15mm/0.59” Mounting depth:171mm/6.7” DUSTPROOF: The dust cover prevents dust and other debris from entering the magnetic gap, resulting in abnormal sound, and meanwhile reinforces the high pitch. FIDELITY: High-intensity magnetic field wouldn't allow the subwoofer to be fuzzy under high power operation, and will present massive bass.
