i do have the mini dsp mic, that i bought for my self to see the frequency response of my subwoofer as the acoustic behaviour of my room.

i was trying to figure out , how i can read the average frequency response of my sub, to see how well is perform in the range for example of 18hz to 120hz. after ran the sweep test and specify the range of frequency that i decide to, i do not see the real average.


could you please someone here in the forum tell me how to?

my sub is palladium p312w dual.

You can’t get an average from a single reading - it’s basic mathematics. Typically the way to do averaging is to take readings at different seating locations. Is that what you’re trying to accomplish?

Well

What i need is the average of dB in octave band of 25hz, 31hz, 53hz, 63hz, 80hz, 100hz, 125hz in one sweept test.

Which is the sum off all db and divide between the numbers of frequency giving you the average response of the subwoofer. And see how flat is your frequency respond. I usually do with a spl meter and excel sheet using a test tones in those frequency. But is to much tedious....

if you run a sweet test with a mic...suppose to give those readings , and do the math.

That won’t give you an average frequency response of the sub (not sure what such information is good for anyway). It will only get you a SPL average of those frequencies.

I'm with Wayne on this one... what you are looking for has zero value is providing any relevant or useful information. What you want to look at is the overall frequency response of the sub from about 15-200Hz, and you can smooth that response to get a better looking average of that response.
