Neumann KH80 vs JBL 308

It's hard to find because it's been measured quite a while ago. I'll try it. Some things can be easily recognized as color plot graphs.

Such things include dispersion pattern in the relevant plane

The term "amplification" may not be a good distinguishing characteristic for horns. Horns control dispersion, which increases directed energy along a defined plane. They don't amplify signals... at all.

Wave guides control direction while minimizing signal losses to an *attenuator*.

The horn is an acoustical transformer. It acousticaly impedance matches the driver ( compression) to the air making it much more efficient. Think trombone. It also controls directivity. Full explanation, plus lots more horn info here: https://www.grc.com/acoustics/an-introduction-to-horn-theory.pdf
A waveguide on the other hand just controls directivity. So as far as im concerned a horn is for compression drivers a wave guide for other drivers. The rest is marketing BS.

Yup, they're horns, not waveguides.
