Just a note,
I have replaced the wires running to my sats and it makes quite a differance, especially eliminating static and outside noises. Actually, I did just because I have wall-mounted mine, and the stocks were much too short, but it's really rather easy if you have a little experience with a saudering iron.
And, for the guy that said the crossover was at 250hz.....To my knowledge, it's actually at 120, pretty darn good for MM speakers, and part of the reason ppl liked these things so much.
