DIY 60 hz hyperbolic bass horn
Here's an upcoming project that's bound to generate amazing sound and perhaps social interest. In my primary sound system, there's a lack of presence in the upper bass/lower midrange. This is the only portion of my system that's not horn loaded.
This simply won't do.
I happen to have a copy of Hornresp and a burning desire to put it to work. I also have a ton of drivers to tinker with, many of them pro-audio types.
It turns out that JBL's little 2123 10" midrange driver can do a remarkable job of making mid-bass when coupled to the proper horn. Hornresp depicts a very smooth response curve and plenty of range. I wish to operate this horn between 60 and 400 hz.
I'll keep posting my results to this page as they occur.

I drew 9 segments--one every 10 inches--you can use more for greater accuracy. The plywood disks required for this project can be created with the following dimensions:
Hornresp suggests that I'll have a fairly easy time operating the horn between 60 and 400hz. Because the horn is crescent shaped, there'll probably be some loss in the upper frequencies. Only time will tell. Because the crescent is gradual, the upper end roll off shouldn't be excessive.
