eters.

But first... A Word on Our Crossovers
The multiband crossovers in the AERO.one consist of second order Linkwitz Reilly style
filters that are hard coded to specific frequencies. As the processing required for television
applications is not as aggressive as other mediums, little advantage can be gained from
changing these values, and the remainder of the processing relies on these characteristics
remaining constant.
For reference, the crossover frequencies are:
• Band 1 (Low Bass): 20 Hz - 60 Hz
• Band 2 (Mid Bass): 30 Hz - 200 Hz
• Band 3 (Low Mid): 170 Hz - 1.15 kHz
• Band 4 (High Mid): 950 Hz - 6.1 kHz
• Band 5 (Brilliance): 5.2 kHz - 24 kHz
