• Digital signal processor box. You get 2 channels in (l+r). You can split that into 8 channels out. Those outputs can be left, right or both (mono), each of the 8 can be individually EQ’d and assigned a frequency band.
    I’ll be using 5 outputs. #1 is left channel 80-800hz, #2 is the same but for right channel. 3&4 are 800-20khz left and right, #5 is 20-80hz mono to the subwoofer.
    The idea is that none of the drivers is being given frequencies it’s no good at reproducing.
    Each channel needs d/a conversion. Each DAC has 2 channels so I need 3 of them.
