Re: Your Experiences With Constant Directivity Horns
Thanks, guys. You're making me blush.Duke, you're too understated. Fred Thompson and I were just talking about that last night at dinner. You've made quite a few nice contributions in the field yourself.

Re: Your Experiences With Constant Directivity Horns
There are lots of horns that are good, it really depends on what you need and/or expect, such as frequency band, angular coverage, symmetrical or asymetrical, and quality of pattern control. For example, if you just need a tweeter, then the horn doesn't ...

Re: Your Experiences With Constant Directivity Horns
Then, what would be your product recommendations for decent non-diffractive CD horns, whether cheap or expensive?

Re: Your Experiences With Constant Directivity Horns
A diffraction slot is useful for widening dispersion, but it is not useful for controlling the pattern other than that. A diffraction slot can only widen the pattern; It cannot constrain the pattern. It also is very frequency dependent, not constant at...

Re: Your Experiences With Constant Directivity Horns
A clarification, please: When you mention "constant directivity" in a HF horn, can I assume that you're referring to the typical diffraction slot style? I ask, because other designs claim constant directivity using non-diffractive throat geometries.

Re: Your Experiences With Constand Directivety Horns
I agree with everything Wayne said about the advantages of CD horns. I believe the sonic qualities that come from constant directivity to be audible and well worthwhile. In my experience, CD horns and waveguides can be hard to cross over. Wayne's paper...

Re: Your Experiences With Constand Directivety Horns
I've owned some pro speakers with constant directivity HF horns. The pair I still use for my band use are EV Sx-100 stage monitors/small venue speakers. These have a CD horn crossed at 1.8 kHz. These sound very good. I used them as my home speakers for se...

Re: Your Experiences With Constant Directivity Horns
I prefer constant directivity horns. When constant directivity is observed through the midrange upwards, the reverberent field is more uniform. The sound is much more natural throughout the room. This requires midrange and tweeter horns be matched, hav...

Re: Learned some more audio truth outdoors
Pretty much every speaker you've ever seen me do has this as one of its main design objectives. Controlled directivity is part and parcel of the design process. That's why my loudspeakers sound consistent throughout the room, and tonal balance is good e...

Re: Any opinions on these cheap waveguides?
I have a pair but haven't built anything with them. They are not constant directivity devices - the walls are curved, not straight - so I'd be inclined to call them "horns" instead of a "waveguides". I was hoping for an inexpensive constant directivity ...
