Let's look at this
Are you sure the compression driver isn't damaged? I'll bet something has happened to it, possibly debris behind the phase plug or in the gap. You may have just gotten a bad driver with a damaged diaphragm or something.I ask because I've never heard or ...

Klipschorn vs seven π cornerhorn
I think the Klipschorn is a fine speaker that sounds good in spite of its warts. It was designed in the 1940's. That's impressive to me, all by itself.On the other hand, a folded basshorn used to 400Hz is not a good idea. Middle "C" on a piano is 260Hz...

Re: Imaging with Pi Speakers
I've always found speakers that project a nearly uniform radiation pattern sound most natural.The thing is, the opposite case - speakers with very non-uniform radiation pattern - create a pinpoint "pocket" where sound is best. The trick is to carefully p...

Re: why not
I've built some smaller three-way speakers, some that I thought were quite good. But they never work as well off-axis, which means the reverberent field isn't as uniform. You can't make a small midrange with unform directivity. If it's small, it must be...

DI matching
DI is an abbreviation for directivity index. DI matching is a design philosophy of making crossover near the frequency where the direct radiator directivity collapses to be near that of the horn. It makes off-axis response closer to a straight line, act...

Re: Polar, not bears.
You can design a speaker with any directional pattern you like. Prosound speakers tend to be offered with narrower patterns than home hifi speakers. For example, you can find prosound speakers with 90°, 60° and even 40° patterns. Most home hifi speaker...

Re: likely 'in room' sound?
I've always found that the cornerhorn sounds best, mostly because the directivity is uniform throughout the audio band. The model cornerhorn you choose is more a cost and size consideration. As for room interaction, I suggest modeling with Cara. The on...
