Where to find 1000uF bipolar for crossover

aarsoe · 9th May 2005, 02:15 PM

Hi

I am doing a speaker renovation project where I need to locate a pair of 1000uF 100VDC caps - pref. of good quality.
Problem is that I havent found anything beside a Motor starter cap in that size and voltage - but it is an aluminium cap, and I have no clue on how it would sound....

Have also been thinking about using Blackgates, but they dont come in with that voltage, so I would need to use 4 x 1000uF 50V pr speaker to achieve the same - and that is way to expensive.

The company that originally did the caps dont do them any more and the speaker manufactor is out of parts, so that is also a dead end.

Any ideas - that dont kill the budget?

should also mention that I have been thinking about using 2 x 1000uF 200V regular caps mounted opposite to create bi-polar function - but I have never heard of anyone doing it for a crossover. So if you have any experience in doing this, please let me know..

3x300uF + 1x100uF
I think you can get them in these values at 100V.
Pretty big values for a crossover. Lot of people were wondering what I was doing when I got to 40uF.

Get 3 pcs. 330 bipolar from Comar capacitors.....those are some of the best out there, both when talking bipolars and PP film caps.

You got that the wrong way round. You would need 2x 2000uF 50V caps back to back to make a bipolar 1000uF 100V.
