I have had and still do have Snell speakers. Snell matched everything up in the crossovers using all sorts of different capacitor values and types for that matter. I have found that in a set of speakers that the crossover capacitors are of different values in each speakers crossover network. No a huge difference but indeed, a difference. I love every set of Snell's that I have. Three sets, J III's , E III's and C/V's. I will heed the above advice and use as close as possible to the same as original value. If it says 2uF then no 2.2uF's. Thanks @Deang.
