large cap choices for a 3 way

rjj45

I'm finishing up a 3 way, and can live with a 200uF NP electrolytic for the woofers 2nd order LP.
But I"m not sure about using a 150uF NP electrolytic for the mid HP.
Looks like even the cheapest Met-Poly caps will set me back about $50 for each side.

Q: Are there any NP electrolytics that sound better than other brands?
Have I missed any online poly cap sales that provide a better value?

I have used the Bennic brand NP Electrolytic caps Madisound sells.  I have also used the ones PE sells.  I still sleep well at night.

Cheap enough that multiples are still cheap.

Wow that’s super cheap. Not quite as cheap as the yellow 10uf caps from Madisound but close. Are the two leads on each end tied together internally? I am gonna grab some of those..

Thanks Ben - pretty much exactly what I was looking for. No NPs for the mids! woohoo

Is a 150uF doing anything on a mid? 200Hz?

I got some about 12 years ago used them for my Canvas and 3CR-Ti builds. They measured out to 18.8uF at the time. I need to get some more of them...

Yah buddy. I'm using 2X TB W4-1320SIF in a MTM, and those guys really don't like anything under about 100Hz over about 80 dB . Since I always like to "crank it up" a bit, HP around 200Hz 2nd order keeps them happy and clean. I really like the TBs since I've gotten them dialed in.

Ordered Qty 40 of those 20uF polys. I'm sure they will come in handy. Thanks again Wolfie!

Let us know what the multiple leads are all about.

There's a word for it, JR knows it, but I don't recall what it is.
