The JBL Stage1 42F is a 4-inch (100mm) 2-way coaxial car speaker designed as an affordable, high-quality upgrade from factory speakers. It uses JBL’s patented Plus One woofer cone architecture, which provides more overall cone surface area than other speakers of the same size, resulting in higher sensitivity and increased low-frequency output.
A rugged polypropylene woofer and PEI balanced dome tweeter combine for durable, clear sound reproduction. The speaker is supplied without a grille, keeping the installation profile low and versatile for a wide range of factory speaker locations.
