    Close but no cigar? XO question

    I am ordering the components for my XO's, and the circuit on the highpass is a third order, C1 = 8.0 µF, C2 = 12.0 µF, L1 = 0.27 mH.

    The place I was ordering from only has 8.2 µF caps and listed them when I asked them for pricing for the components. Is being off by the 2.5% a big deal? They do match components for speakers pairs, so it seems like "noise" withing the tolerance of the whole speaker system.

    Brandon,

    Standard capacitors are usually either 10% tolerance or 5% tolerance. It's unlikely the small difference you're describing would make a significant difference in a standard crossover network. Some high Q filter types are more sensitive to component tolerance, but even there 2% would be considered pretty good.

    Regards,

    Jon
