MAIN FEATURES

 

The KICKER ST 1.5" (38mm) Street Series Bullet Tweeter is designed for competition-level SPL and high-output car audio systems, delivering clear, detailed vocals that can cut through powerful bass. Its highly efficient horn-loaded aluminium diaphragm provides extreme output while maintaining smooth vocal reproduction.

The PA-style bullet tweeter can be installed using front or rear mounting options, with included trim bezel options for flexible installation. Spring-loaded terminals accept 16 AWG speaker wire, while the built-in 6dB high-pass crossover provides convenient frequency protection and integration.

With a 4-ohm impedance, 108dB sensitivity and 3kHz–20kHz frequency response, the ST4TW is designed for efficient high-output performance. A field-replaceable voice-coil assembly is also available, helping extend the life of the tweeter in demanding applications.
