About the DAX
The Apogee DAX (Dedicated Active Crossover) is an outboard electronic crossover system originally supplied with specific Apogee Acoustics ribbon loudspeakers, with several versions including DAX 1 and DAX 3, optimized for models such as the Duetta Signature, Caliper Signature, Diva, Mini Grand, and Studio Grand. The more universal DAX 1 is a dual-channel, dual-passband, non-inverting active crossover (approximately 330 Hz for full-range ribbons) in a full-width chassis with an external power supply, providing configurable level and balance controls for woofer and mid/tweeter bands and supporting both balanced and unbalanced connections depending on version. Later and model-specific variants use different crossover frequencies and slopes tailored to their matched speaker systems, but all DAX units serve as active crossovers to replace or supplement the speakers' passive networks for improved control, dynamics, and system integration.
