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. Highs give a crisp sound against the bass and these ones look and sound GREAT. Made of metal instead of plastic, easy to install , and look pretty cool.
Summary: These are very GOOD set, i would buy them again if needed more, i have a set running off of an amp and sound really nice and loud. and the other set off of my cd player, you don't need an amp to make them sound great. i ran a set off of an amp just to get that extra boost.
