All-in-one solution
JBL designed their Stage Series subwoofers to give you great bass at an attractive price. Now they've created the Stage 1200S enclosure for people who prefer a matched sub-and-box solution.
Handles up to 250 watts
The Stage 1200S sealed enclosure comes loaded with one Stage 122 12" subwoofer, which features a polypropylene cone with a rubber surround. The sub handles up to 250 watts RMS, and its 2-ohm impedance makes it a great match for most sub amplifiers. The enclosure is made from 5/8" MDF covered with black carpet to withstand the bumps and bruises of life in a car. JBL tunes the enclosure to maximize the sub's performance, so you can count on impressive low-end punch.
