Measuring with BK2012 is very fast - faster than ARTA. Just two buttons when delay is set. When done save as ASCII (by using autosequence). Polars are stored in 36 curves as Z-Axis. Excel 2007 must be used because older does not accept more than 256 columns
Below is resulting data for those who willing to try make a crossover: Mummy equipped with BC DE500 and 12B100R. Angles: 0,5,10,15,20,30,40,50,60,80,100,120,150,180.

No with 7deg (14deg full) Should I set to 0 deg? Then it is difficult adopt both 1.4 and 1.5 inchers )
Yes, I am almost certain that the throat angle is almost zero degrees on the 951Pb but it would be great if someone could confirm the exact number. I think also the inner diameter is marginally greater that the outer.
This is great! So when can we order?
I don't have it confirmed by Radian or having a sectional drawing of the driver, but I tried to measure it without dismantling the bug screen. According to Guido Behringer the phase plug exit is Ø1.5". I measured 17mm from the exit to the phase plug. This implies a negative half angle of some 4deg.Yes, I am almost certain that the throat angle is almost zero degrees on the 951Pb but it would be great if someone could confirm the exact number.

Please don't blame me 0deg should be close enough?Negative angle is worst thing because demoulding requires positive angle.
