Sound Barrier SB752D — 2″ Throat High Frequency Driver with 3″ Voice Coil
SB752D Overview
The Sound Barrier SB752D is a high-output compression driver engineered for professional loudspeaker systems requiring extended high-frequency reproduction and reliable power handling. Built around a 3″ voice coil and titanium diaphragm, the SB752D delivers a frequency range of 800 Hz to 18 kHz with a sensitivity rating of 105 dB, making it well-suited for high-SPL applications in touring, fixed installation, and system integration. At 200W peak power handling and a nominal impedance of 8 ohms, this driver is a capable choice for audio engineers and system integrators specifying horn-loaded HF components. Its bolt-on mounting configuration simplifies integration into a wide range of enclosure and horn designs.
The SB752D’s compact form factor, measuring 6.5″ in overall diameter and 2.75″ in depth, allows for straightforward installation in space-constrained enclosures without sacrificing performance or thermal capacity.
