If you do, the end of the filter report will show the adjustment for it (which is rounded off to the nearest gain increment you specify for your AVR), provided you have set up MSO to specify the AVR characteristics. See the Tools, Application Options, Hardware dialog options for specifying your AVR options.
You may want to experiment with limiting the gain value range in the individual gain block to get higher total output, so one sub is not so much different in level from the other.
Thanks, I've been busy with other stuff since but now I have some results and suggestions.
First picture is the REW measurement before and after mso on MLP. The result is pretty much the same as predicted by MSO and much flatter than before.
The second picture are MSO's predicted curve.
Suggestions: I do my eq in the Inuke 3000dsp that I have for my subs. It's a common subwoofer amplifier with built in dsp. That DSP has limitations that the minidsp don't have. If you could make som options to limit MSO to Inukes limitations it would be good, and help make the result more exact.
I'll try to list them here:
Gain for a peq filter, can only be input with .0 or .5
Frequency for a peq filter, has only one decimal, like 40.4
Quality has only 2 decimals, like 3.45
Besides PEQ it has
LS6 (low shelving EQ, with a 6 dB slope)
LS12 (low shelving EQ, with a 12 dB slope)
HS6 (high shelving EQ, with a 6 dB slope)
HS12 (high shelving EQ, with a 12 dB slope)
Only frequency and gain can be altered after it's choosen in the Inuke's software.
Is that in MSO an LF shelf first order och second order limited to 6 or 12 db?
