Is there a tutorial for making adjustments on the DSP to what you see in the graph? or is it along the lines of oh, you have a 3db null at 50hz so you bump up 50hz +3db to compensate?
I've not dived in yet (paranoid that my amp will have issues since the loud pop when I turned it on...but I can't test on anything..) but I should have the sub boxes in my room next week!
This is a very basic tutorial on how to :create a spl graph in REW using umik mic create the filters for an Inuke amp apply filters in Inuke amp If you want a detailed how to use REW click on this link...
You generally can't compensate nulls with DSP. Move the speakers (or the couch) to try to reduce the null. Sometimes, a few inches will do the trick. Typically, another null will show up, so it's always a trade off. Once you have the best FR with the least issues with nulls, pull down peaks to flatten the FR
