rear loaded horn

farriswheel · 27th July 2007, 12:10 AM

Hello, im new to this forum!

i have been trying to design horns for sometime now. I tried to download the program here but it wouldn't work(said something about winzip). I am trying to design a rear loaded horn, using this calculator http://melhuish.org/audio/exphypcalc.html
though when it shows the numbers, i have no idea what im looking at. Can anyone help me determine the horn length? along with some other aspects.. I heard the length was 1/4 wavelength of cutoff frequency but im not for sure on that.

Thanks!

Hi farriswheel,

The calculator you are using is good, but only part of the story.

I recommend you try hornresp

have a look at Paul's excellent page here:
http://www.diyaudio.com/wiki/index.p...n+in+2+minutes!

hornresp is complicated but worth it if you wish to design a bass horn.

You could also look a my page which has some other info.

Have fun.

thanks for the information!

for some reason i can't run hornresp.

I think i have some of the design down. But how im getting the length is 1130/cutoff frequency/4. However i dont know whether it is correct or not.
