Jabo KH-55A horn

Posted by j_s on August 31, 2009 at 00:18:09:
I'd like to make a larger horn to go with my Jabo KH-55A horn, but am unsure if they are an exponential horn? I'm looking to make a horn with a throat of 250mm or 300mm and a mouth up to the width of a standard sheet of plywood (so just under 1200mm). I've not had any luck with the horn calculators on the internet, how low could I go? I'm looking to use either a 18sound 10M600 or 12MB1000. Any ideas?
Thanks!
