Rather than splitting the amplified signal inside the speaker with passive components, this unit divides the audio signal at line level, before amplification, so each horn section is fed by its own dedicated amplifier channel. The result is tighter driver control, lower distortion, and a coherent presentation. It is the same active DSP hardware Klipsch supplies with the Jubilee, running firmware that Roy Delgado tuned specifically for the La Scala AL6.\u003c\/p\u003e\u003cp\u003eActive crossovers work by processing the source signal digitally, applying the exact crossover slopes, time alignment, and equalization that the loudspeaker designer specified. Because the filtering happens before power amplification, the amplifier no longer wrestles with reactive passive networks, and the drivers see a cleaner, more precisely shaped signal. This approach requires bi-amplification, meaning two amplifier channels per speaker, one for the horn loaded low frequency section and one for the horn loaded compression driver.\u003c\/p\u003e\u003cp\u003eThis crossover is intended for La Scala AL6 owners who want the fullest expression of the design. The firmware is tuned for this speaker specifically, so it is not a general purpose crossover for other loudspeakers.
