Sound Barrier SB180D — 1″ High Frequency Driver with 2″ Voice Coil
SB180D Overview
The Sound Barrier SB180D is a professional high frequency compression driver built around a 1″ throat and 2″ voice coil configuration, delivering 90W RMS / 180W peak power handling across a 1kHz to 16kHz frequency range. Its phenolic diaphragm and 30 oz. magnet structure provide consistent high-output performance with a rated sensitivity of 105 dB at a nominal impedance of 8 ohms. With distortion rated at a maximum of 0.05%, the SB180D is suited for system integrators, touring companies, and installers requiring reliable HF reproduction in two-way or three-way loudspeaker systems. The screw-on mounting type simplifies horn compatibility and field replacement.
At 4.6 lb. with a compact 4.7″ diameter and 3.2″ depth, the SB180D integrates efficiently into both custom enclosure builds and replacement driver applications without adding excessive weight to the system.
