Post Subject: A possible solution to better impulse?Posted by morespeakers2 on: 2/6/2013

I have been looking in to mid bass horn designs to experiment with lately for the 4 way horn pa I am working on. As usual Good Sound Club always is on the Google search when dealing with any kind of horns. Although my reply to your post may be a few years too late, you may still find the info I found of interest to deal with your poor impulse issue if it is still a problem and I am actually addressing correctly the issue you are having.

Talking with John Inlow about his 100hz mid bass horn using the B&C 12pe32 12" driver I asked him about the "bi-conical throat" on this quasi exponential horn. I could not find much info on any kind of bi-conical audio horn designs and only found some sort of radio antenna. John said he saw it used on higher frequency audio horns so why not try it in some of the horns that went lower? Well he is quite enthusiastic and reports that the throat really helped the impulse response as shown at the bottom of the page if the "diy 100hz midbass horn" found on the left column of the home page. He also reports sucess using the bi-conical throat on some of the other horns he had designed going even lower.

I am planning to get some Masonite and/or some double thick appliance box cardboard to play with some upperbass and bass horn designs in the near future. Will let you know I find if you are interested, will try this "biconical throat" as well.
