• 2" exit, neodymium magnet, 3" voice coil compression driver
provides 75Wrms power handling and 107dB sensitivity
• New, patent-applied-for phase plug design methodology
suppresses cavity resonances at higher frequencies
• Titanium diaphragm, deep drawn to increase stiffness and
reduce distortion
• Lower compression ratio reduces air non-linearity and allows for
higher maximum SPL
• Rolled polyimide surround improves stiffness control, further
lowering distortion
• A curved coherent wavefront, optimised for horn loading
