^^ No smoothing. If you are familiar with REW, the solid line down below the legend area at the very bottom of my graph indicates no smoothing. I only post unsmoothing graph for subs. I use 1/6 or 1/12 for speakers measurements. I use XT32 with subEQ from my Denon X4000 avr. I do not know if they can play 3db below reference at 10hz as I cannot locate my spl to calibrate REW which allows me to run a higher sweep than -12db MV. Currently any sweep over -12db MV causes an error in REW. With that's being said, from my graph, my subs probably can play reference loud or -3db at 10hz (Dom, correct me if I am wrong here). I also apply a 6db low shelf filter centered at 60hz from my HTPC jriver MC19 which is NOT shown on the posted graph. Some day, if I can find an easy way to use REW to measure my jriver low shelf response, I will post that graph.
