minidsp2x4HD how to distribute 10 bands ?

[Darek K]

This is setup 2+1 and my question is about EQing mains.

In REW/EQ is section Filter tasks and there are Match range values.

What is better ?
Distribute 10 bands over whole range of frequencies 20-20kHz or maybe from 20-500Hz or something else.


Here is my measurment of right channel

For starters, this measurement stinks. I wouldn't trust it all above 1-200 Hz as it stands, or not without a fair bit of smoothing anyway. (1/12 oct - 1/6 oct) Averaging takes across multiple spots or using the moving microphone method (MMM) is much advised. Your choices of smoothing and EQ flatness target will then affect how much of a hard job the EQ has... if the graph is too wiggly all your points may be used up before a good match with the target response is achieved.

Use Var smoothing in REW for a more representable view of the frequency response. Anyway, restrict EQ to something like 20-300 Hz. Read up on room modes to understand why.
