AlexO has gotten my La Scala juices flowing again, so I gots some technical-wise questions I'm wondering if any of the geniuses here might know how to answer.
Picture of La Scala...
1) Ya know that ad for B&W speakers where they show the dimpled port flare?
What would it do for the sound of a horn if the actual horn itself was dimpled like that?
2) When you listen to a horn speaker, how much of the sound is affected/produced (?) by the surface of the horn, anyway? I don't even know how to begin to answer that question. Without resonances figured in, would the material the surface of the horn is made of make a difference? Would a wood surfaced horn sound different from plastic or metal? Again, this is assuming no resonance effect. I would think that "smooth is smooth" with regard to the horn surface, eh?
3) How much do resonance effects affect the sound of a horn? I've never really seen modders or manufacturers go after the idea of damping the putside of a horn to make the speaker sound better.
I recall that old Klipsch horns were metal, and they changed, but I don't if it was because metal horn materials "rang" or if it was a cost saving maneuver.
I was thinking of making a glue/sand or liquidy rubber/sand mixture and then masking off the interrior and driver parts of the horns and then dipping the outer part of the horn into the mix to create a seamless damping layer around the outside of the horn. Any idea what it might do to the sound?
3) In the big picture of the La Scala, you can see that the horn mounts are on the back of the speaker's baffle (see picture above.) Would either...
A) Moving the mount so it is flush with the baffle make a difference?
B) Sanding out a continuation of the horn's shape into the baffle make more of a difference, or could I do more harm than good?
C) Applying a damping layer like felt around that inner baffle area make a difference?
4) For the bass, would creating a "rounder" path for the horn's travel passage be a good idea? You know, taking the sharp angled apsects and maybe putting in some "curvier" inserts to make the "horn's" path maybe less reflective?
Whew, OK, that's a start. I'd be very appreciative of any knowledge shared or sources given to learn more!
