Installation and cabinet guidance
Support the 6.4 kg horn securely and check its complete profile and fixing arrangement against the drawing.
Fit a compatible one-inch compression driver separately. Match the throat, fixing interface and any required adapter before assembly.
Choose the crossover, power handling and amplifier load for the fitted driver and complete horn/driver combination. The published curves show a combined system, not a standalone electrical response for the horn.
