Does the shape of a horn matter ?

[ginetto61]

Hello !

Looking at compression drivers I see that horns come with different shapes: squared, rectangular, elliptical and circular :blink:
Is the shape an important factor or not ? why a designer chooses one shape against another ? :o:
Thank you very much and kind regards,:D

Ask 4 different designers this question, and you will get 6 different answers.

The shape is a important factor, but people don't agree wich is best.

It also has to do with dispersion (coverage) a horn that covers a wide area with constant response is not an easy thing to do

Thank you very much for your reply
I understand there is no a shape that is intrinsically the best
Nevertheless I am very intrigued by all the horn design issue
If anyone could direct me to posts or links describing just the basic principle of horn design I would be very grateful
Thank you very much and kind regards,

Thank you very much Gentlemen !

now i know where to start and what to study.
It seems to me that there is a growing interest for horns also among so called "audiophile" people and not only professional users ;)
A great way to get both high efficiency and low distortion
A lot of people are converting to horn loaded drivers and valve amps
And the marriage sounds as a good one :applaud:

Thanks a lot again
Kind regards,:D

Let's be careful out there. SPL meters and OSHA guidelines are your friends.

Thank you so much for your valuable advice
I was not aware of this possibility used as I am to low efficiency and relatively high distorting home speakers
They become annoying before any hearing damage
Very impressive indeed. I think it is a case of too much of a good thing
Just out of curiosity which series of JBL drivers are you referring at ?
Thanks so much again
Kind regards,

Gino
