New tweeters installed last night, didn't get to fully hear how they sounded till this morning on my way to work. Definitely like them though they can get a bit pitchy at extremely high levels but I can't complain for the price I paid for them. They actually make me wanna replace the infinity kappa speakers I also have up front and put mid drivers in there place. Only problem is I've only been able to find three 4" mid drivers. Still gotta install my rear 6.5's though and I know that'll help with the mid's I'm missing right now. Overall I'm liking the way my system is coming together.
