ATH Tritonia-M Waveguide by Marcel Batík
Kindly 3D printed and donated for testing by MDuyck1292.
Tested with both my Celestion CDX1-1731 and a B&C DH450-8 that was also provided by MDuyck1292.

Final Notes:
Excellent uniform directivity performance in both axis, dispersion appears to come in very close to the rating. On the polar graphs it may look like there is some waist banding below 2kHz but that's partially some minor diffraction artifacts from the test jig, that range will be influenced by the exact baffle size/design these get mounted in anyways.
