Acoustic Horn Design – The Easy Way (Ath4)

Just an experiment - 1.4" throat driven by flat wavefront (axisymmetric free-standing waveguide ~ ⌀450 x 150 mm):

a) throat angle = 0 deg

b) throat angle = 50 deg

mbat, saw you indicate that you are looking to be able to make a speaker without the big baffle. how does a freestanding horn let you achieve this though?

since you still need another driver still in some kind of baffle, and its probably still gonna be pretty big, wont it pretty much be a zero sum game?
 
Reducing an enclosure volume to half is not a small deal 🙂
I guess this is very much subjective - for me the free standing horn is far less obtrusive. Also, as long as you don't need the (mid)woofer to produce low bass, its box can be pretty small as well - or even an open baffle.
 
Good to see the experimental profiles mabat!
These are the answers to my questions, so to speak.

To me personally, the horn in post # 3429 is most interesting, but who am I? 😉
The directivity, while not optimal, is still nothing to sneeze at.


I like this already:
