Description
The Kicker ST4TW is a 1.5-inch Street Series bullet tweeter designed for competition-level SPL systems and extreme high-frequency output. Its larger horn-reinforced aluminum diaphragm and 108 dB sensitivity provide strong projection for stunt walls, pro-audio doors and other high-output systems.
The tweeter is sold individually and supports front-mount, rear-mount and trim-bezel installation options. A 6 dB/octave inline high-pass crossover is included, and the voice-coil assembly is field replaceable.
