Post Subject: Economic stimulus package for horn building hoodlums?Posted by serenechaos on: 4/29/2009

I do not know what is meant by “close bottom” or “open bottomless”-- please expound?
I do not know of importance of enemys death to this topic.

There is a long thread in the subwoofer section of "devil audio" about tapped horns.
John mentioned getting a flatter response than I was able to using the same driver (4012HO definemax) I was working with.
I wrote, asking for advise, he suggested adding a inductor in series w/ the driver.
Also cutting the throat the full size of the driver, not smaller for compression ratio (!!!)
He has built others since, is now using two drivers per cab; and says it works better.

I looked @ many designs, spent a while studying Danley's & the patent trying to figure out what was going on with it, and the resonators, etc.

Size of the THs I built is ~ 16" x 16" x 80".

implementation--ok, here we go; now none of what I said means anything...
different room, different system...
mine is all "unfinished/evaluating/work in progress;" experiments--listen, change, listen, repeat at this point...
only the tapped horns, and "what I use above 10kHz" stays.
passive line leval crossover, seperate amps.
This is all building towards:
the tapped horn is to ~70Hz.
a mid-bass horn from ~70 - ~500Hz.
a low-mid horn from ~ 500 - 1kHz. (what you call fundamental channel)
a high-mid horn from ~1kHz - 10kHz.
a ribbon from 10kHz up.
