The JBL Stage 102 is a 10-inch (250mm) car subwoofer built for high-output, low-distortion bass. It handles 225W RMS and 900W peak power. The Stage series also comes in 8-inch and 12-inch sizes.
The woofer cone is polypropylene, which is lightweight yet stiff. It is paired with a hi-roll rubber surround. Both are automotive-grade materials, chosen for clean reproduction and durability, and the design suits a variety of amplifiers.
Each subwoofer is individually voiced and tuned for high SPL and low distortion. JBL puts its speakers through reliability testing that includes freezing, baking, shaking, ultraviolet light exposure and days of full-power operation.
