I using this setup for the first. I have 2 mackie srm450 v1 and 1 behringer 1800D- Pro with the Driverack PA

I'm going to use a 2x3 setup

the specs for the mackie

frequency Range (-10 dB) 45Hz - 20KHz
Frequency Response (±3 dB) 55Hz - 18kHz
Maximum Peak SPL @ 1m 127 dB

Specs for Behringer:

Frequency response 32 Hz - 200 Hz (-10 dB)
40 Hz - 150 Hz (+/-3 dB)

The setup is going to be 2x3

Behringger

HPF 40 HZ BW 18
LPF 100 HZ LR 24

SRM

HPF 100 H LR 24

    I believe that he is saying he doesn't trust the numbers that B'ger is throwing at you. The set-up is OK. If you want to check that 40hz spec get a 40hz tone source then...
    1) Set output volume to 1/2 of normal level
    2) Set a LR24 filter @ 45hz
    3) Play the tone and note the volume.
    4) Roll the filter to 40hz and note the volume.
    5) Roll to 35hz and note the volume.
    Use the relative volumes to see if you are producing 40hz. If filters @ 45 and 40 have little difference...not reaching 40hz. If filters @ 40 and 35 have little difference... reaching 40hz.
    This method is not conclusive nor scientific, but should yield some type of result. :mrgreen:
    PS - I picked those frequencies willy nilly, and you might want to play a 50 or 60hz tone to get a relative volume.
