Peak Momentary Power Output：2400 Watts RMS Power:800 Watts Max Power:1600 Watts Sensitivity:82.7dB 1W/1m Impedance:Dual 2 ohm Resonance frequency:31.13 Hz Qms:3.889 Qes:0.946 Qts:0.761 Linear cone excursion:+/- 19mm/0.74” Mounting depth:181mm/7.1” 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.
