Do we know what are the test conditions? Done outdoor?
Measuring a speaker this large and heavy was difficult to say the least. Jeff and I hoisted the speaker on top of a 6-foot section of rigging. On top of that rigging, we placed a slip mat, and then I used a digital compass to measure the change in angle. The microphone was placed at the appropriate height using a specially designed microphone stand. Measurement equipment included a MicW (BSWA) M215 with calibrated capsule, a 1khz Calibrator, a Motu 828x, and Room EQ Wizard. Graphs were generated using VITUIX CAD.
yes it is doable. Tutorial is Here. Also done by SDX-LV.Is it possible to trace/extrapolate the Spinorama of this JTR?
It took me some times but I always wanted to understand how contour plots are computed. I had to learn and implement a few algorithms. I could have take the easy way and use some libraries but it was a better experience like this.
Here are 2 previews, i took the same colors as 3D3A and the same scale to make it easy to compare them.
