Constant Directivity
…have agendas too.The conical horn is actually the only shape that provides constant directivity. It starts to lose pattern control at some low frequency point based on its size but above that point, it has constant directivity through its passband…

Re: Uniform Directivity - How important is it?
…working assumption is that speakers with constant beamwidth always sound better than speakers that don't, provided everything else is equal.
A second assumption is that speakers with non-constant beamwidth but uniform-directivity - those having just …

π Constant Directivity Cornerhorn: Bass Bin Design Details
…
I did consider making the bass bin of my constant directivity cornerhorns using a folded horn, like the 12π hornsub. But upon careful considerations, I found a lot of disadvantages in that approach. These considerations are described in some detail in…

Consider constant directivity cornerhorns
…planning to put the mains in corners. A constant directivity cornerhorn is designed to be placed there, and maximizes the benefit of that configuration:
Speaker placement and wavefront launchYou can use three π speakers in or near corners too, but if …

Constant directivity verses on-axis EQ for non-uniform directivity (aka baffle step filters)
…is especially true for speakers that have constant directivity because baffle step is caused by a directivity change. If a speaker has constant directivity, it can't possibly have the so called baffle step.
Baffle StepOf course, most speakers don't have…

Matching directivity
…guess. Look at it this way. The 2404 has constant directivity above 7KHz, and has a real nice transition in directivity from 4 to 7Khz. Crossing the 511-B at 5 or so should put you where the Altec is starting to narrow and you 2404 is starting to go …
