Hey, jzagaja, I've noticed on a forum you mentioned waiting the ND4015BE. Have you had the chance listening to this CD?

Not yet. Our friend is 18sound owner friend and he just tested Ti version so far. Not bad but Radian 951 (Truextent) is still no. 1

Default Help needed in making a decision

A system I am working on would benefit from some input. I am following Lynn Olson's Beyond the Ariel project where he describes the LTO Apollo here:

Beyond the Ariel

My project will be a "poor man's" effort and favor an elliptical format for the horn. I want a smaller form factor for the horn. My crossover point will be determined. I would like any input for the relative merits to choose between the E-JMLC 600:

AutoTech E-JMLC-600 - AutoTech Waveguides - Waveguides DIY Sound Group

or the Iwata 600:

AutoTech Iwata-600 - AutoTech Horns - Horns DIY Sound Group

Lynn's description of the Azurahorn 450 should serve as a bull's eye of sorts:

"The horn is an Azurahorn AH425, which is a custom-designed (bespoke) LeCleac'h with a T ratio of 0.707 and matched for a compression driver with an exit angle of 8 degrees. The AH425 diameter is 16.5" and works best in free-air mounting with about 2 inches of separation from the top of the bass cabinet."


TIA

Ejmlc has twice as wide HF dispersion. Use it with DE500 or similar. Disadvantage? Carefully measure power reponse and equalize otherwise at some angles and higher loudnesses you can hear some midrange tonal abberrations. Much like waveguides. Iwata is easier to work with.
