Rugged polypropylene cones deliver powerful bass and long life. PEI-balanced tweeters play soft high frequencies smoothly and seamlessly.
Injection-moulded, UV-resistant JBL polypropylene diaphragm
The Stage2 Autobox’s 5-inch JBL subwoofer cone is designed for maximum strength and sensitivity. The result is better low-frequency response and a full, powerful musical character.
JBL PEI dome tweeter
The woofer is coupled to a PEI balanced dome tweeter for a car hi-fi sound signature with clear high-end frequencies. Stage2 car speaker systems play smooth, clear high frequencies with good dispersion thanks to the PEI balanced dome tweeters.
Rigorous JBL reliability testing
Stage2 JBL speakers are subjected to environmental tests that other speakers would not be able to withstand. JBL subjects them to extreme cold, heat, vibration and ultraviolet light, and runs them at full power for days on end to withstand the demanding climate of a car.
