Maybe a misnomer, cuz I cant post every graph and I unfortunately didn't name my past measurements properly to know which test correlated with which treatment adjustments/additions I made.
So basically...here's just a BEFORE & AFTER, both at 500ms.
I really did try to pull the "average" graphs from my first tests about 1.5yrs ago and just today.
EDIT* There is a some EQing going on here too on my EMU Patchmix DSP, esp at 80hz. I'd like to ween myself off of it lol.
One thing that interests me is how little the actual SPL changes on the low end. It actually kinda bummed me out when I just threw a new 6" trap in on a floor-wall corner, hoping to resolve some dips/peaks but didn't notice any change of SPL. It kind of made me feel like my attempts are futile and I should give up on trying to treat this room. Then I decided to pull up some of my old/original tests to compare and...wow. I remember when I used to have to set my ms to 1000 just to view it all.
Its funny to see that 35-40hz & 60hz resonances still lingering strong. Any tips on that?
I think the resonance at 20-28hz might be from the ported rear of the HS80m's. I have them plugged at the moment, and are plugged in only the "after" graph. I may try to test again tomorrow with them unplugged.
