Conclusion: I love the midrange and directional tweeters on these. I put 4 of these in a 2010 ford f150 fx4 super crew. It was an upgrade of sound overall really hear all the highs and midrange off of factory head unit.
Summary: I have read the other reviews and I just don't understand them. The factory speakers on my 2010 F150 sounded much better than these. I am using the stock Sync head unit and these speakers just sound horrible.
Pros: None. Zero.
Cons: Awful sound. Muddy bass competing with flat highs. Just absolutely the worst sounding speakers.
Summary: These aren't going to thump your crappy sub-compact car down the street, but they will give you a very broad spectrum of accurate and pleasing audio. I'm a recording engineer by trade and these are as good as you can get unless you're willing to use an amp and spend a lot more $$$ per speaker.
Pros: Accurate, non fatiguing, smooth
Cons: For BEST results, they really should be amped. Not bad at all from factory deck/amp though!
