Sadik has done an awesome job with these waveguides..
Here is a pic of the waveguide resting on top of a cabinet housing 2 x Satori WO24P 9.5inch woofers (just for scale)..

Lovely build of those gorgeous looking wave guides. Dont mean to hijack the thread...but can you please elaborate a bit on these horns. The frequency range, efficiency and compression driver used etc. Not everyday that we get to see horns around here

These are the EXAR 400 horns from Marcel Batik (mabat on diyaudio). It accommodates 1inch compression drivers

ATH - Advanced-Transition Horns

The frequency range can probably be anywhere from 800Hz to 20kHz depending upon the system configuration.
Here are my polar measurements of a 1-inch BMS 4550 on this horn (raw responses)
My plan is to also try out this horn with the SB Audience Rosso 65 1.4inch CD with a custom 1inch adaptor designed by mabat.
Measurements taken 1m away from horn mouth (gated at 4.1ms)

On axis frequency response and impedance measurement together

VituixCAD plots
Normalized directivity computed with reference axis as 10 degrees off axis

Here is what a rough active filtering on this horn can do



And here is a rough first-cut passive filter

Thanks for sharing...the measurements look sweet. And a wide range of 800 to 20k is excellent to have without any crossovers in between. All the best to trying out the CD with the throat adapter.

Very good polar charts Vineeth. There are no crossing lines in polars meaning a very good performance
