Summary: Purchase went as expected, no hang ups - no long wait for delivery. Nice little speakers. Still only 5-1/4" so while it is better than most any other similar sized speaker, it's still a small driver and only capable of so much mid-bass. Great vocals and highs - not "tinny" tweeters either, very smooth sounding even at high levels. Also capable of delivering good performance with head-unit output or being driven by amplifier.
Conclusion: I recently purchased a pair of JL audio 525 speakers wit tweeters and components and the sound better than the mtx I had. But they are plenty loud if u like to blast ur music like me ur ears will be ringing a little. Tweeters were kinda hard to position but it was my first install so that mite be it also. All u need is the extra wire which u could get at any electronic store. Good buy for me.
