Question about crossovers...

I am contemplating upgrading the crossovers from a non-Polk speaker. The HF side uses three caps, valued at 5.1, 6.8 and 10 mf wired in parallel. Is there a special reason why the manufacturer went this route iso going with a single 22mf cap?

:confused:

    I don't know that caring has much to do with it, I just can't think of any reason the mfg would take that approach unless they had the caps laying around for other combination's that their products might require.

    Maybe someone more familiar with XO design & modification could jump in.

    That's a very large value for a HF circuit.

    Tannoy did the same thing in the 60's-80's. It could have been for a few reasons, to keep ESR down, space constraints, or that's what values they used most{save costs}.

    What speakers are these out of?
