Great Midbass and Clear HIghs

I bought these to replace factory speakers in My 2011 Buick Regal with Harmon Kardon system. Three of the 9 speakers stop working. I bought two sets for the front and back doors. They fit with a little grinding of the inner rear door panels, front speakers fit with no alteration. The midbass compliments my JL sub-woofer and I can hear sounds in music I wasn't hearing before because of the great tweeters. I like that you can adjust the tweeter with the push of a button and they swivel for you liking. The 75 watt RMS is good because my car has a factory amplifier! I should have replaced those factory speakers years ago! I can't think of any negatives on these speakers.
