Hi forum,
I'm have build a corner horn equipped with JBL units (K145, 2445, 2404) and jbl 2397 for midrange.
You can see the pictures here : http://www.hifi4all.dk/forum/forum_p...TID=33192&PN=3 but, sorry, it's on danish. There is 7 folders, with some pictures. But anyway, my questions are:
Has somebody played with the wood radial horn ala TAD and Fostex (see the link for what I'm considering, http://www.fostexinternational.com/d...ial-Horn.shtml) , the H200 horn (fn 240 Hz).
The advise I need is the exponential curvature to construct after. Or the math. to do the curve. Anybody here who has some experiance in that?
I have used the jbl2397 mid horn but find that, for the cornerhorn it is nescessary to go even below 500 Hz. First I have done some new "finns" to build a biggere 2397 a like horn but the radial horn came accross.
Another question. Is it possible to drive the jbl2445 below 500 Hz (my point is 250 Hz). I use 24 dB/oct. filters. Is it possible to get an output or is it to low compared with the spl above 500 Hz?
Looking forward to here any comments
Regards
Flemming
