Kicker ST4TW 1.5" Pro Audio Dual Mount Bullet Tweeter Single 4-ohm 49ST4TW

The ST4TW is a single 1.5-inch bullet tweeter for systems built around extreme output. The larger horn-loaded aluminum diaphragm reaches 108 dB sensitivity and starts working at 3 kHz, so it carries more of the upper midrange than a 1-inch tweeter and keeps vocals intelligible when midbass and subwoofers are running hard. The 4-ohm voice coil takes 15 to 50 watts RMS and 100 watts peak, and the included inline 6 dB high-pass crossover keeps low frequencies out of the diaphragm without a separate passive network. Mounting hardware covers both approaches: round and square flanges plus a backing nut and screws allow front or rear panel mounting on doors, kick panels, pods or wall builds. Spring-loaded terminals accept up to 16 AWG wire for quick connections. Mounting depth is 1-1/4 inches behind a 2-7/8-inch hole. If the diaphragm is ever damaged, the ST4TRK recone kit rebuilds the tweeter in the field. Pick this one over the 1-inch version when the system runs very high SPL and you want the added output and lower crossover point.
