Large voice coils provide power handling, while careful selection of suspension and cone components results in exceptional sensitivity. These dedicated narrow-bandwidth midranges offer the lowest distortion at given output of any midrange available.

Power calculated on rated minumum impedance. Loudspeaker in free air. Power on Continuous Program is defined as 3 dB greater than the Nominal rating. Applied RMS Voltage is set to 2.83 V for 8 ohms Nominal Impedance. Thiele-Small parameters are measured after a high level 20 Hz sine wave preconditioning test.
