A couple of new pictures.

SEOS-18 eDrawing file. It accepts 1.4 and 1.5 drivers, roundover set at 15 inches for mating with 15" woofers.
90deg waveguides expand very quickly and so length is really short - 8.5 inches and you want cross low I suppose. Length should be above 12".
Does it have to be a 90deg for a waveguide?
What about 80deg or 70deg?
How do the parameters change if a different angle is chosen?

I'm selfish and want SEOS18 1.4" with 0deg 🙂 Also have 1.5" driver that is optimized for 0deg throat.
Yupp, Be edition 🙂 At the moment it is playing in a mock-up with E-OS15... Really nice WG and driver - I can recommend this combo!
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.

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.
0deg should be close enough?
