The speakers of the Stage2 series produce a distinctive JBL concert sound in your car, minivan or SUV at an astonishingly low price. The polypropylene woofer impresses with its excellent extended bass range and the low mid-range range. The woofer is complemented by a PEI-balanced dome tweeter, which fills the characteristic sound with bright peak frequencies. Another plus point of the Stage 2 series is the JBL frame design, which makes it easy to insert into each factory opening without having to change the vehicle, the location or the loudspeaker system itself. Features High-quality materials for highest reliability: Polypropylene cones and rubber beads made of high-quality materials tested to automotive standards offer pure reproduction and high stability - with Easy Listening on the boulevard or when it is time to turn up fully. It's all about the bass! Standard reliability test by HARMAN: JBL speakers undergo a rigorous testing procedure that would not pass less powerful speakers. JBL exposes them to high heat, cold and vibrations, irradiated them with UV light and let them run for days at full power. Fully tuned: The speakers are carefully tuned to ensure a high sound pressure level and low distortion. This means that the usual specifications as well as the characteristic acoustics of the loudspeakers are taken into account when tuning to the JBL sound.
