Thanks for that ethan, I'll try it. Donsolo, I found a mic calibration file for the ecm8000. I reckon something might be out to be honest. I'd like to know if there's a flaw in my measuring with etf (like I said I had to convince it to work)
I have a motu2408mkII lightpiped into a d8b, so i was doing all the routing required in the mackie (left channel back to the program, right channel to the speakers>microphone>program) etf couldn't use my motu mixer and kept wanting to use the virus ti as a soundcard (I don't use it as such) So I was feeding it the right thing at the right input and it seemed to be working but I don't know if the round trip of having to go thru the mackie and back would mess with it's timing and give the skewed response seen above, what do you think ethan?

I'm at the stage now where i want to know I've done all I can, I was expecting the top end to be smooth, given that I've addressed the relfections but I was in there last night and my ears told me the tweaks were a big improvement over what I had. For example, the proper lows (30-60) really seem full now and provide a solid bedrock for the frequency spectrum, still haven't got all the 100hz I'm looking for but I'm going to have to accept that unless I move room I'm probably not going to get much better.

I have one final plan though, I'm going to change the back wall from 'diffusion' if you can call it that lol to absorption. I'm going to make a panel, floor to ceiling which juts out 45degrees top and bottom (to make corner traps for ceiling/wall and floor/wall) 4 inches thick, 4 from the wall, with a membrane on the back (unconventional I know but it's working for me!) I'm gonna take the sheet out behind the corner traps and super chunk them, then put the trap back, for all four corners.

That should increase my room/absorption ratio quite alot. I might put some 4" foam tiles (studiospares) I have lying around on the ceiling in the rear of the room too, given that I only have a thin carpet and no treatment on the roof.
