The FTX0820 is a 8″ diameter cast frame common motor coaxial speaker, with a single ferrite magnet that acts as a motor for both LF and HF drivers saving space and weight.
With a 2″ voice coil, the speaker provides a 400W continuous / 200W (AES standard) power rating with a 94dB LF sensitivity (103dB HF sensitivity). It incorporates a 1.4″ voice coil compression driver to deliver a 70Hz to 20kHz frequency response.
