You don’t need to have the measurement at around 0 dB. The “Import” tab has the gain adjustment for exactly this purpose.
I have taken a look at your FDP file. Here are a few suggested minor adjustments:
– On the “Mag Adjust” tab, change the gain of the “High Shelf” to -7.9 dB.
– On the “Auto Mag” tab, change the “Min Freq” to 90 Hz.
>> I imported a speaker response and created a fir file. But the result seems hardly doing anything.
From what is shown on the “Export” tab, the FIR filter should definitely be audible.
All I can suggest is checking that the processor is importing the file and that the filter is enabled. What processors are you using and what FIR filter format did you export?
