Newbie Review by Nick Riveara Newbie Product Reviewer:
The JBL GT120 Car Subwoofer features: polypropylene cone with butyl rubber surround, dual 40-ounce magnets, power range 55-250 watts RMS, peak power 1,000 watts, frequency range 23-450 Hz, sensitivity 93 dB SPL, impedance 4 ohms, top mount depth 6", sealed box volume 1.0 cubic feet, and ported box volume 2.25 cubic feet. The GT120 12" subwoofer boasts a polypropylene cone that's lightweight and ultra-efficient, so you won't need as much power to drive your low notes. But if you like to crank it up, the butyl rubber surround, dual 40-ounce magnets, and progressive spider ensure that this woofer won't bottom out when the going gets tough.
