Hey am thinking of pairing Ci22955 with WBFK30019 in parallel. LPF 10R 22uF (556.49Hz), HPF 3R 100uF (530.57Hz). Is that right? Any advice would be appreciated!

In this configuration use CI as full range. WBFK is not really good for range below 4kHz. Also get 30095 instead of 30019 because -019 has no spout.

Ahh I see. Should I put the HPF at 1kHz (3.3R 47uF) instead? And let Ci play the full range.

Don't use resistor and just put 1.5uF cap on WBFK - that's around 5kHz cross-over point.
CI into 2mm ID tubing with damper from 680-2200 - anything will work but will remove more and more midrange with higher resistance.

Won't the Ci need a resistor to match WBFK output?

I was sorta thinking about resistor, mostly becuase whole setup will have very low impedance (and be very sensitive) But I think CI and WBFK would match. WBFK has very high output over 3kHz, And CI starts to roll-off at 3kHz.
If you get too much bass, there you'll have your answer.

Anyone had good results with acrylic dye's?  I think I remember someone on this thread using dye from Hobby Lobby.  I can't justify buying Egger in diff. colors now so I would like to mix on an individual basis.  What are my options?  Does it degrade the strength?
 
Thanks HFers!

I have been using acrylic artist ink with exceptional results, this was a tip from Briancortez who has branched out and started up http://www.sizzle-audio.com

It mixes pretty well and colors are vibrant.

Is it with gas chamber?

Understood. Just one last question. What's the formula you used for calculation? Seems like I'm doing something wrong here.
1/(2*pi*R*C), 1/(2*3.1415*1*0.0000015)? Doesn't equate to 5k. Or is the resistance from the Ci calculated in too?

I used online calculator and used WBFK impedance curve to find correct spot. WBFK has around 20-22 Ohms around 5-5.3kHz so if you use 1.5uF you should get cut-off frquency at that range.

No, I still have to go glycerin bath to fully cure. It has given me a much more consistent cure though, it has 10 bulbs!

Interesting. From what I read about the Polylux, it says it removes all the oxygen so no baths are required. Or do you have a different model that does not remove the oxygen?
