Does anyone has experience in bending horns. Im thinking about horn going to 3-4kHz. Very long horn. How far can I bend it?

You could bend it but it's unlikely to sound good.

Horns below 500 hz can be bent or folded. Lots of models on the market that sound good. Horns from 500 Hz to 5000 Hz should not be bent or folded. Not many folded or bent mid horns that sound good. Bent mid horns may sound like a paging horn. If you must make a bent mid horn make the curve as smooth as possible.

I understand that option 2(with straight walls) is failure.
How about option 2? Lets say the horn canal would be drilled so the shape could be any. Any chance of reaching at least 3kHz? to connect it to nice 1" driver? I want to try some more HiFi crossover range. Or only straight horns like Unity can go so high? Any examples of bend horns? Good or bad. Edited by gen0me - 12 February 2017 at 1:57pm |

Why does the horn need to be so long, to need to have a fold? Whats the intended lower cut off?

To reproduce everything over basses. Right now Im in the middle of making one playing to 1kHz. Im curious if it is possible with different HF driver. If this one sounds good.

As long as the horn expansion is always smooth and continuous, in theory a bend should not matter. But when you get into it the radius of a bend vs frequency will probably begin to have an effect.
You can see the effect in an impedance plots when the peaks that due to horn transmission are damped in magnitude as you go up in frequency, walls are absorbing the sound. |

What can be the radius?
Can I simulate bend in akabak? |

Have a look at the DR**0 horns by Bill Fitzmaurice for ideas

what effect will the bend have on directivity? Out of interest.

I checked them(DR200) but cant find any info how high is crossover. Only size of HF horns could get ROUGH idea. What are recommended speakers?
On intuition the directivity should be dictated by shape of bend end and exit of horn. Ofc bend should be narrow to keep similar patchlengths. Now I see where DR shapes came from. Am I right? Whats DR directivity? |
