crossovers...

[Andrew B Gransden]

I have a single Vitavox crossover dividing @ 500 cps between an S2 and a K15 40. There is no model #; it simply syays "VITAVOX 550 C.P.S. FILTER" and it has an added-on brightness control.
First question:
Would a CN232 be compatible with this for my second set of speakers?
Second question:
Why does the S2 driver sound like shite when I bi-amp using an active crossover at the same frequency (550hz)?
and to Romy (if you are tuned in): how can I make my own for under $10 as you suggested in a recent post? (actually this is an open question...)
There is obviously something in the crossover which tames the S2 driver (what's a Zobel?)
Thanks, Andrew

Andy, first off all answering your other question: no, steam is not good for the cones. Actually any moisture is not suggested. Although the V15 are impregnated with moisture resistance thing but I would still do not go it. I remember as I screwed very good sound of some very good think paper drivers juts by wet-wiping the 53 years old dust from thier cones.

Now about the crossover. I do not know what CN232 exactly has but a few years ago when I opened the CN232 it looked like a regular second order with a little impedance normalization network. I do would not use it as Vitavox did. First of all I do not accept the second order at speaker level and second I do not eclectically correct resonanses. Also, I have no idea what you do in that ?active crossover at the same frequency?. If you want something very simple then tray a regular serial cap against 15 Ohm of the driver. If you used the original diaphragms than you my cross wherever you want: the S2 runs with then more or less flat. If you use the contemporary diaphragms then stay with higher crossover point.

Thanks Romy. Can you give me some more info on an "impedance normalization network"? How does that work? And how will the same thing be accomplished by using a single cap? (although I like the idea...)

BTW, my bid didn't make it in time on the CN 232 xover on ebay last night... Anyone have a 550 cps unit for sale (in the event I can't put Romy's plan into action)
