Product Info

This is a 1 inch 4 ohm transducer, member of the H family. This family design features a treated Ti dome, large rear chamber for low resonant frequency, and a ferrofluid cooled the motor. The large motor allow for robust power handling capacity. The tweeter comes with a faceplate with recessed mounting holes, for easy installation into the desired application. The faceplate has a horn geometry for increased sensitivity.
