In this discussion the term horn will refer to designs based on Webster's horn equation (conical, exponential, Bessel, constant directivity, and so on), while the term waveguide will refer to those specifically derived in terms of the oblate spheroidal coordinate system described by Geddes [1], [2]. September 2012. On Loudspeaker Directivity Part 1 Article By Jeff Poth I've talked a lot about directivity in these pages, particularly in my OSWG Building Oblate Spheroid Waveguides and Heil AMT1 And The Heil Horn articles. Directivity is a very significant topic, poorly understood by many people, so a more focused review of the topic is warranted. HF is provided by two large format close-spaced compression drivers coupled to a 2-inch (50.8mm) constant directivity horn. Four bandwidth optimized 10-inch (254mm) diameter woofers in a 2 x 2 array provide substantial low frequency. The CFA-2 is a direct weather design that features a three layer stainless steel grill assembly.

Could he still hold directivity so low with similar power handling? It is a constant directivity horn based on a conical horn and a oblate spheroid MARIO DI COLA, DAVIDE DOLDI HORN'S MOUTH AND DIRECTIVITY AES 109th CONVENTION, LOS ANGELES, 2000 SEPTEMBER 22-25 3 The fundamental issues related to constant directivity performances in such systems can be: • The profile of the horn/waveguide: it should allow the horn to be theoretically a constant directivity device.
