Product Info

This 1inch diaphragm inch exit compression driver is a cost effective solution for use in professional sound reinforcement systems. The pure titanium diaphragm ensures solid and controlled vibration to the highest frequencies. The phase plug was studied extensively to optimize the HF level, and ensures a wide smooth response characteristic. The use of high quality ferrofluid combined with extensive verification testing has resulted in a transducer which is extremely reliable.
