JBL Stage1 51F5-1/4" 150W 2-WayCoaxial

JBL Stage1 51F — 5-1/4" 2-way coaxial car speaker with 150W peak power handling, designed to replace factory-fitted speakers with noticeably better clarity and bass response.

The Stage1 51F fits the common 5-1/4" speaker opening found in many mid-size vehicles and uses a 2-way coaxial design that integrates a woofer and tweeter in a single unit, simplifying installation without requiring separate crossover mounting. JBL's Plus One cone technology uses a larger cone surface area than competing speakers in the same diameter class, delivering more output and deeper bass from the same mounting cutout. Polypropylene cone construction resists the temperature and humidity variations typical of vehicle environments for long-term reliability.
