i do it and i did it, but as a newcomer you have to sort out all the infos...not that easy!

(This is normal, I have written about it many times. Those large bass drivers have a lot of inductance in Voice Coil, the inductance that warys with excursion BTW and while the driver operates the generated inductance in the driver “talks” with the low-pass inductance in filters, canceling it out. At the time I used passive low-pass filter on my upperbass horn I was utilizing inductor of 2 or 3 times more than it was necessary. Actually a passive low-pass crossover for bass driver might not be circulated but should be made by measuring the actual driver response behind the crossover. That is nomal.


thats a reason i would like to see a model in pspice....this things have nothing to do with perception, thats math...like everything, but this is simple.the parameters of a horn should be no problem.like a transformer with all its strenghts and shortcomings.
maybe i change my mind over time, right now i want to stay with 1 poweramp and my phono.
at the moment , the only i thing i really would not change is my phono(lcr eq, mu-follower with 80h inductors insteat of r, 5842, i´m proud of this crazy idea, sounds strange,lifelike)
i know, you understand what i´m working on..to build something on a solid foundation, with the chance to improve it without wasting money. a fact that i dont like.but a fact.

macondo: searched it, but its far out;-) you and jezzie work on another base.

at first i will get the midbass right, will be back later!

thx,klaus
