Help with crossover for Accuton and Eton?

[guru]

Hi !

I need some help with designing a crossover for Accuton C92-6 and Eton Er4. Have found some on internet for Er4 but nothing for C92...Hope you can help

speaker data can be found on...

(sorry for my english)

Try this 4th filter ( very approsimative):

Er4: resistor series; 8,2microF series;0,16mH shunt; 8,2microF series; 1 mH shunt.
(Resistor 2,2- 4,7 ohm : listen!)

wf: 1 mH series; 17 microF shunt; 0,40 mH series; 3,7 microF shunt
+ Zobel CR (33 microF - 10 ohm) shunt. stop.
Zobel is deliberatedbly"overcompensated" , eventually try 27, 22, 15 microF. No problem .

Polarity: no one know if red is positive or negative . Can you measure an impulse response ? Otherwise try normal and reversed ( i don't know your offset ).
I hope you haven't doubt on wiring a "normal" 4tH passive crossover!

I know ER4 very well. Do not close rear face with a plate as a normal ribbon because it destroy the sound! A little rear box full cotton or dacron can absorb rear radiation (as come a cone midrange).
