25hz 114db 1W-1M Bass Horn

Well, here's a project that I hope proves to be interesting. My brother-in-law has the desire to own a bass horn for his new home--he has a very large attic space that will be the perfect home for a bass horn. The living room ceiling is vaulted, so the bottom of the 4' x 4' horn's mouth will be located at the 9 foot level. I'm sticking this baby in a corner, so I get to use the 0.5 x pi setting in Hornresp. The predicted performance is shown in the second graphic, below. You'll notice that 4 Lab 12 drivers are connected 2S x 2P (2 series/2 parallel) to keep the output impedance at a level that won't drive the power amp crazy.


I'll post pics as progress develops.
