UPDATED AT 2RD APR 2021
I modified my turning method, switch between the motion boom and other great sounding speaker as usual, but I use the frequency generator app this time.
Set the frequency exactly as the EQ setting 80hz/150hz/300hz…and so . Trim the EQ 1 by 1 by compare those speaker loudness at special frequency.
And here is the EQ setting for motion boom compared to Helsinki Neutral mode:
I also making an EQ setting to compare to VIFA OSLO, but not done yet, I hope I can finish it at this holiday.
And this is the best setting last time I did before I change the turning method, I change the profile name to boombox.
I spend a week to turn the motion boom eq by my ear and finally I get this.
