Will the horn be a mid in a three way or HF unit in a two way? If a three way, match the directivity at the top end to the HF driver your considering.

Tweeter only. This is a midrange horn:

If we summarize all experiences and ideal would be Altec 416 coax in a midrange horn (200Hz) with full rollback (sphere) that forms bass reflex box tuned to 30-35Hz plus EOS waveguide inside speaker radiates from ground aka "Flooder"...

I must say DE500 with 12B100R is a nice combo - very, clean precise sound, tight bass, trully recommended.

Jzagaja; Would you recommend a horn for the DE500?

I've been looking at your Iwata 600 a couple of times as they provide relatively short height (vertical) at a relatively low recommended x-over frequency. And I want to build a compact two-way floor-standing system.

So for instance your recommended Beyma element @ 90L + DE500 and Iwata 600?

I would probably experiment with an active x-over setup, unless someone recommends a good passive diy-design that works.

Regards :-)

I want to say that Geddes measured an included angle of 13 degrees for the DE250. I wonder how accurate that list is.

I didn't measure 13 degrees. I worked for B&C and 6 degrees was on the drawings.
