Hi guys,

I have opened up 2 pairs of speakers to see what the crossovers looked like and if possible upgrade especially the capacitors. The speakers in questions are the Dynaudio Audience 82 in my main system and Pioneer HPM-900 I acquired recently as fixer-uppers.

I have found some caps in my Dynaudios that I am not sure I've identified correctly.

There are 2 big yellow caps marked:
Bennic, BO3, 82mfd, 100WV

My interpretation is that this is a 82milliFarad, 100V cap. This sounds like a rather big value. Can this be right?

There are several blue boxy caps marked:
6v8k, 100V, 373 MKT BC
1v5k, 250V, 373 MKT BC

I am not sure how to read the values for these caps.

I have been thinking of using the Claritycaps DIYcable sells for upgrades but if I can't find the right values, no sense in trying to change.

Can anyone help me make sense of these caps?

Groeten,

Ferdi

Not good form to respond to my own post....

I think I've now identified the large Bennic caps as 82mju and 100V and BO3 Axial type from the Bennic homepage.

The 82's are a larger 3 way speaker so if the 82mfd capacitor is in the woofer circuit, this sounds correct. The mfd is "micro farad" or otherwise seen as 82uF.

Hi ferdi, Just to follow up with your intent to upgrade the crossovers, I would not concern myself too much with the  large capacitors found in the woofer circuit. For the woofers, it will be inductors that are in series with the circuit. Replacing these would require knowing not only their inductance but their resistance as well. If you change the inductor with another of a great difference in resistance, the sound could be altered in a negative way.
 The capacitors you want to concentrate on are in the high pass filter for the tweeter and upper bandpass filter for the midrange.

HI Bill, thanks for your response. I will continue studying with your input.

I was hoping I could get away with just replacing capacitors, not the inductors.
