I think it was three versions back...2002?
I recall detanting the operation of these passive thingys over a glass of wine and several paragraphs.
I can send you more recones if you want therapy.
""I wondered if it might be a pop preventer of some sort, thanks again for the clarification. One last question, (sorry to ask so many) if instead of doing a 4430 clone, I build a three way using 2123H as a midrange and put the 2425H/2344A on top, is the compensation still recommended, or is this just a compensation when used 2 way for the midrange? Your answers have been much appreciated. I am going towards a 4430 clone, but it troubles me having these NOS 2123H just laying here! It has cooled off a little here and I am ready to start cutting wood for cabs, need to make up my mind. Lord, I'm like an old woman sometimes""
Yeah been there and done almost exactly that with the 2122H...nice.
Just run the 3134 version stock in the high pass filter with all the passive eq as is.
Russell,
Pm Rob (super mod) for some more specifics one the 2123.
