Where is the thread describing someone's efforts to apply the EnABL pattern to the mouth of a horn? I'm sure it has been tried, but the search phrase "EnABL mouth horn" only turns up a precious few threads!
Perhaps I haven't read carefully enough the descriptions of the EnABL process, or I misunderstand how it works. I think, in a nutshell, it has something to do with the way the wave of energy is transferred from one material (the driver cone) to another (the air). There is an inherent, abrupt and unpleasant impedance mismatch here. A lot of the energy fails to "shake loose" from the cone, and gets reflected back down towards the voice coil. No end of foolishness results (inefficiency, cone breakup, etc).
After reading a bit, perhaps a similar event occurs in most horns? The size of the mouth is "compromised", and cannot be as large as it ought. There is an impedance mismatch, and a resulting sonic shock wave occurs where the front tries to escape from the mouth. I would think applying some kind of EnABL pattern (on a larger scale) might be helpful here. Maybe if I had more than a few dozen stick-on cork or rubber feet, and decorated all around the mouth...
Am I getting this all wrong?
edit: never mind, it seems all the discussion is in Multi-Way. No sense creating a clutter here...
