I wanted to test the off axis response 4pi without the SBIR effects of 2pi mounting, this gives a clearer view of the behavior of the speaker alone. These measurements use a short gate time so the resolution below 1000hz is poor and very poor below 500hz. I was interested in mainly the high frequency behavior so this was not a problem.

The following measurements were performed on my smaller indoor turntable.

Measurements were taken at 2.83v / 1M on the tweeter axis.

Measurements are gated at 5ms, smoothing applied is 1/48th octave.
