No I didn't. Edit: I just took one. It's about 92dB to the ratshack meter a few dB below reference. Your guess is as good as mine as to how far off the SPL meter is at 6Hz.
You need the Divx 5 codec. Grab the free one here http://download.divx.com/divx/DivX505Bundle.exe Don't bother installing their player, just the codec.
