Measurement Details:

The following measurements were performed on my 10' tall outdoor turntable, measurements taken at 2.83v / 2M just below the tweeter axis (bottom screws on the waveguide) and scaled 6dB to approximate 2.83v/1M level. The stock grill was installed for these measurements. The measurements are gated at 14ms and blended to diffraction adjusted nearfield woofer response below 280hz.

Smoothing applied is 1/48th octave.
