i've got 136v polyglass components. the tweeters can be somewhat harsh, but if you play with the eq and tone them down with the crossover (mine have 0, -2, and -4dB settings) they'll shine. i've actually got mine set to 0 and have the highs somewhat turned up on my hu because the staging in my car sucks. i'm planning on moving the tweeters up out of the doors sometime soon...as soon as i have a little free time. if i put my head close to the floor to account for the poor staging, the speakers sound awesome. give them time and tune your eq...hopefully you've got the imprint kit so you can do that.
