= 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. https://www.users.bigpond.com/dmcbean 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 https://www.eminence.com Fs=22 Qts=0.4 Vas=125L xmax=12mm pe=400watt -melhuish's horn site-read there for a start. https://www.melhuish.org/audio/horn.html mike.e learns about basshorns-the continuing saga mike.e asks about basshorns https://www.f16.parsimony.net/forum27133/messages/2036.htm smooth flare vs stepped straight section https://www.f16.parsimony.net/forum27133/messages/2075.htm horn folding https://www.f16.parsimony.net/forum27133/messages/2126.htm basshorn labhorn https://www.f16.parsimony.net/forum27133/messages/2112.htm horn front chambers https://www.f16.parsimony.net/forum27133/messages/2224.htm -https://www.audioasylum.com -do a search there -the 'labsub'text file what it is,why,acoustic power,basshorn theory and application. https://www.geocities.com/xobt/TD.rtf More labsub info https://camphuisen.com/ https://www.prosoundweb.com/lsp https://home.zonnet.nl/chriscam/data/topics/490.html and mcbeans hornresp program at work- https://www.geocities.com/basshornguy im on these forums audioroundtable.com diysubwoofers.org at times decware forums at times you wont see me on audiophile forums ;-) my new site www.geocities.com/xobt -Rapids basshorn- https://hem.passagen.se/sajberrapid |
