Bass Horns
<mike.e/mikee12345>
How do horns work?
Horns are basically acoustic transformers. Because of this transformation, the horn driver is a fundamentally different design to most radiating-type drivers. It is only recently that horns can be modeled similar to sealed and ported styles of box. These programs convert drivers and boxesinto electro mechanical parts eg inductors resistors and capacitors. For horns this isnt so easy. Fortunately David Mcbean has produced this program for no charge purely for his own interest.

For horn loading, you want a driver with a low Qts and a higher (relatively) Fs
Although people DID use to reccomend using high EPB woofers-this is generally only for wideband usage. For narrow band basshorn, a less 'optimal ' woofer may be used
for example-
the lab12 from

Fs=22
Qts=0.4
Vas=125L
xmax=12mm
pe=400watt
