OK, I found a place in Canada with pretty good prices, Q Components in Waterloo, ON. A few questions, They seem to have two grades of capacitor, cheap and expensive. I am currently going to build the center channel fromthe Audax website, if all goes well, I'll build the rest. The total $ for all the capacitors for the center channel crossover(s) is $10 for the cheap ones, and $92 for the better ones. Considering the entire project is well under $300 (cdn), this is alot more. Well, is it $80 better? My current plan is to use the cheaper capacitors for now, upgrade once the box is done and I am satisfied. Trying to limit my overall $ exposure, don't need to spend all the money and pack it away 1/2 done.. Advice please?
