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: Conical HF Horn?
I've read something of the sort concerning the old EV Mantaray stadium horns. Intuition tells me that the dense vertical interference will help mask the apparent apex difference. (Yes? Maybe?) The singular task of finding just the right HF horn for t...

Re: Conical HF Horn?
If you're not planning to array the tweeter horn, a diffraction slot in the throat of an otherwise CD flare is the ticket. When sized properly, a throat like this will give you constant directivity all the way up through the top octave.

Re: new wooden horn!
The π wood tweeter is a radial horn, with straight side walls that set a constant 90° horizontal pattern. The throat is shaped so that constant directivity is maintained all the way through the top octave, not just to 8-10kHz like some other CD designs. ...

Re: 4 pi speaker options
Each series has a different size cabinet, with exception of the Stage and Professional Series, which are the same. In those designs, the electro-mechanical specs of the drivers used makes cabinet tuning similar.I am really fond of the Professional Series...

Re: 1:1 throat area
Klipsch's rubber throat does that, you're right. But as you've said, it was done on undersized basshorns (smaller than 1/4λ) having compression and a front chamber. Might be useful on a smaller scale for a midhorn though, so I think it was worth noting....

Re: Compresison ratio and front chamber size
The old ten π was made that way. It was done so that the driver could be installed and removed through the horn mouth. It also made the horn have a very wide bandwidth, giving it usable response up through the midrange. The biggest problem up high was ...

CD horns
One thing that can really help you with the size problem is boundary loading, especially corner loading. Of course, that only works indoors, mostly a home hifi thing. But if you have room corners, use them. They're built-in 90° flares, and they're larg...

Re: Why so many posts here are not about single driver speakers
"Beaming is seen by some as an advantage as it reduces room interaction at the affected frquencies and can be used to tune the speaker by simply aiming the driver at or away from the listener."Yes, but it also causes a reverberant field that emphasizes th...
