In the Thread: The IDEAL horn system
Post Subject: there would be twoPosted by Dominic on: 1/18/2007
one would take full advantage of what can be done in the digital domain so that the horn mouths could be arranged, not for time but to clean up their other interactions. This would be digital the entire way, solid state music files, digital amplification and crossover, preferably in isolated compartments of the same box(for compactness) with signal correction between them. (tube power supplies?) There would of course be one line of tailored amplification per driver. As far as the horns go, at this very week day hour and minute, i'm not sure what would take best advantage. Most likely the sub would be a full front horn, mostly because i would want to keep the air coupling rigid and to maximise transient headroom. It's definitley barbaric in the old school sense - bigger hammer, could potentialy go far too loud for anyone. The midrange area would possibly be anchored by a 100hz horn. With higer mids coming from a short ~350 horn and the HF would preferably be something non dirrectional like an ionic. My main goal concerning how it would be split up would be to put the fundamentals that are important to me at the same point source. Most of the pattern control would be dealt with in the room design. I'm interested in contrast between pieces of music and the different ways artists try to get their message across but without treating technically inferior recording or mastering, or even playing techniques as seccond class citizens. So somehow it would have to grummble the right way at certain compressed pieces while still showing the many colours of very dense and very loud music as well, and other such things. In some ways it should be very highly capable.
The acoustic design of the ideal all analog system is much trickier, you know all the reasons.
I like the timing you get with single horn coaxial setups like Danley's Unity, or Bert's Orphean. IF one could build the driver section so it could work, i think the ideal might be something like a 60 or so (probably horn loading to 70ish) pure expansion, with some sort of constant directivity but magically non-refracting horn coincident with the bass driver that would start maybe in the 150 region which would, like the EAW coax, allow the lower frequency information to pass through.
