I have two boston z6 crossovers. One is definitely working the other one I think has some problems. Let me know if you're interested. They go for $200 brand new each from Boston Acoustics but I can assure you I'm not gonna sell for near that much.
the zapco competition cross overs i was telling you about you asked how can cross overs be comp? well they way i know only is that they use better internal part for the cross overs for each model line instead of cheaper parts to build the cross overs but then again i have never used a cross over so i really dont know either but i sent u a pm.
