Capacitors


Hi,

I can replace the bipolar capacitors with other not-polarized with the same technical values?

Thanks!

Maybe not. The crossover design probably required the high capacitance of the polarized cap and the designer took into account the high ESR into the overall impedance. Replacing that cap with a lower ESR film may throw things out of balance and may require a series resistor.
Hi, I report the data of the crossover scheme:

in high pass band
bennic 26uf - 7 watts in series;
bennic 8uf - 7 watts in parallel;

in low pass
bennic 85uf - 7 watts in parallel.

I proceed step by step to avoid unbalancing the speaker.
Thank you all for the detailed info.

Of course, ideally you measure the ESR of each cap before replacing.

You can do this with a DATS unit or using Room EQ Wizard with a custom jig.

The 26 uF in the high pass doesn't make a lot of sense though. Are you sure?
