Excerpt: Absolutely nothing comes close to these speakers. Clean, clear, power; at any volume. Once you hear these speakers, you can never go back to any thing else. Worth every penny!!!!!!!!! Hears a rumor that they would be discontinued. That would be tragic!
Conclusion: WOW super clear and powerful no distortion at super high listening levels, beautiful imaging, had Focal Utopia 3-ways and these blew them away! Great high end speakers and crossover, true audiophile component set. Use a pioneer DEH-80PRS head unit with these and they sound amazing.

Conclusion: Put these speakers in the front of my GMC Sierra and they kick ass! A little pricey and only used the actually speakers so I have lots of accessories left over. Just had my system tuned up and now that they are broken in I can really crank my stereo up. They sound great loud and I love it loud. Great for me. Bad for everyone else who doesn't like my music. Too bad for them.
Conclusion: This is a Professional Speaker. Meaning its sounds like a pair of studio monitors. They are without a doubt the best sounding speakers you can get at this price. They are very revealing and you will hear everything, including all the crappy recordings and crappy mp3's. Make sure you use a high quality source with these and have them tuned properly for your vehicle. I work in high-end home audio and have ran car audio shops for many years.
Conclusion: Awesome sound and Power handling , no distortion even with high Volume . Driver/Midrange could and should produce a little more bass . Tweeters are almost eardrum piercing . Speakers are very heavy , make sure they are properly secured inside doors . Crossover ( one unit for both channels ) is impressive , both in size and performance . It is about as big as an Amplifier . Depending on location in Vehicle settings on Crossover are easy to adjust .
Conclusion: Absolutely the best sonic quality of any 6-1/2" component set I've ever owned... and I've owned many brands and models. JBL should consider un-discontinuing this product... but perhaps with less functionally-extraneous packaging to reduce the cost. a bit.
Conclusion: This speaker component works good. It has a good fidelity sound. I like them, it was worth buying it. I recommend these speakers, the only important thing is to tune them up really good. I'm talking about the equalization, once you do that really good you'll get the best quality from them, but trust me those sound really good. That's all I can say to the people who want to buy them.
Conclusion: I've had a lot of different component sets and some costing 3-4 times these JBL's but these are simply the best set of 6 1/2's made!! JBL/Harmon knows how to build audio equipment that is second to none. The DIYMA forums tests speakers through Klippel testing and the JBL 660GTi 6 1/2's performed at the top of the list!! These absolutely rock! You won't be disappointed in these components I promise. I just bought two sets since the price dropped and so should you!!!

Conclusion: ... then these speakers are the ones for you. Amazing, crisp sound quality. Best I've ever heard. I listen mostly to trance - and these speakers do this particular style of music such incredible justice! The design stays true to JBL's continuing mission of providing workmanship second to none. They have yet to be properly tuned to my remaining car audio - but currently I catch next to NO distortion. Assured that once I tune them - I will receive none whatsoever.
