F151M-8 1" Ceramic ring radiator compression driver

Despite its minute size, the Eminence F151M-8 ring radiator compression driver delivers monumental performance. Utilizing a phase plug design that improves the distribution of forces over the diaphragm surface results in a driver with lower distortion, smoother frequency response, and increased sensitivity as compared to conventional ring radiator designs.
