These are cheap tweeters. I bought these because I have an Audi TT and I replaced the original speakers and tweeters with a much better system. These were more of a decorative item to fill the hole the previous tweeters left as the new tweeters were mounted in another location. They look really good installed in the doors but they sound terrible next to my 2k system. I left them unplugged and they look good. In my opinion they are a great decorative tweeter but they are cheap so do not expect the sound quality to be great. I gave them 4 stars because they look good and fulfilled my needs. If you are looking for a quality tweeter you will not find one at this price point.
