Summary: Awesome tweeters. Highly recommended, cant beat them for the money. Comes with all you need to install anywhere. I do recommend some bass blockers but that's all you need. I was blown away by how crisp the sound was. These are a must have to complete your aftermarket system.
Summary: Hooked these up in my car with resistors and the sound was good. I like them and for what i paid I can't go wrong. I had these along side 4 6.5" beymas and a 8" beyma. Pushed by a Rockford Fosgate amp. If you want good tweeters for a great price, buy the TWS4 tweeters!
Summary: I bought these tweeters to compliment a 12 inch sub and two 6x9's. I can't beleive how much of a difference they made! I never ran tweeters in my vehicle sound systems before-let me tell you the highs make all the difference in your sound. I was more in to bass and mids.
