Post Subject: off the cuff my horn suggestionPosted by Dominic on: 2/5/2007
I'd put your sub horns above your head. There are some big issues with that but you save a lot on concrete engineering, and assuming space remains in future you could apply what you learned from the overhead wood horns to a more refined bass setup. Obviously doing it twice isn't perfect but the opportunity to get it right seems worth it. It might make some sense to try a foreshortened horn approach, ie large throat like John Dreyer's system here: http://aca.gr/pop_dreyer.htm I don't see a good way to avoid the far field listening position with a straight front horn, one can only hope to mitigate the distance a little bit. It'd be much better i think to shorten the horn from the back and lose a bit of loading than modifying the mouth and mangling the wave front. The science of the acoustics of subsonic horns in the context of an audio installation in an eclosed space is essentially undiscovered country. Several people have tried to do it but as far as i know they've all had major complaints, either of their own or by listeners. Either that or they depend on delay circuits; and still have complaints from purists. Everybody up to now has been experimenting. I keep wondering about what the horn faces, the size of the mouth often approaches other dimensions of the space, or is actually very close to the on axis wall/floor/ceiling.
