The following measurements were performed on my 10' tall outdoor turntable, measurements taken at 2.83v / 2M on the tweeter axis and scaled 6dB for approximate 1w/1m level. Measurements gated at 14ms and blended to diffraction adjusted nearfield woofer response below 300hz. Smoothing applied is 1/48th octave.
