Just a little more info. I put the speaker crossover's in wooden boxes and made them external to the speakers. Seems like all speakers should come this way. Especially for tweakers (Like me).
Also, has anyone tried the speaker breaker from Parts express to protect tweeters? Now, I wired the tweeters using ultra pure .9999 silver wire, so I am reluctant to add a breaker with its crappy wire to the connection.
