Below 30hz issues
So, one of my UXL's was damaged (small child involved). I replaced it with a version 1 SI18. Performed some measurements today and I have lost alot below 30hz.
I corner load (4 corners used). Black is two pa460's opposite corners one front-one back of room along with SI and UXL in the other corners. Purple is pa460's moved to corners on the same side of the room and SI/UXL in the corners on the other side. Measurements were subs combined with center (DIYSG Fusion 8).
I can't figure why 30hz down through 20hz is dropping so quickly. These are all ported subs. pa460's high passed @ 40hz and the 9.5 cuft SI/UXL high passed @ 20hz and low passed @ 70hz in the Inuke dsp.
