Thanks, it is like I said before, a rough draft. It is AMAZING what just a few specific abortion strategically located can accomplish. I utilized the mirror technique to find the optimum panel placement. It's interesting how the frequency response can not really display what the perceived changes are at a 1/3 octave smoothing result. One has to dig much further into not only a more resolute smoothing but looking at much more data. For instance the excessive group delay improvement not to mention the Spectrogram content, using Wavelets. I still have a long way to go with building QRD's and such, but am quite certain I can beat out the nasties in the space. I want to build some Ab-fussers and not just typical QRD's as I feel in a relatively small room I would benefit from some Abfussion as opposed to "just" wooden diffusion. Just my 2 cents as I need to lower the reverb time, yet get a lot of diffusion introduced into the listening space. I will keep updates posted. If anyone is interested I can post the before and after file data, Bare room vs. what you see in the pic above. Just looking at the 1/3 octave FR really tells nothing without, like I said digging deeper into more data.
