JBL 660GTi
60th Anniversary Edition Competition Speaker System

Celebrating JBL's 60th Anniversary, these GTi Special Edition Series speakers will certainly impress even the most critical audiophiles! Imagine a design, so precisely crafted that it produces only the best quality sound a component system could ever produce.

Professional JBL Sound



Trusted JBL Quality:

Using the latest in Laser and Infrared technology, these speakers were thoroughly tested, calibrated, and designed for optimal performance and longevity. JBL's method of design, test, and retesting ensures maximum performance and sets the standard of what is acceptable in the Competition world. In fact, JBL spends at least 100 hours of testing on each speaker at RMS power level to ensure consistent performance and acceptable JBL's high standards.


Tweeter-Level Adjustment with Unipoint



Crystal Clear Sound:

This competition-grade component speaker system is also designed with as little distortion allowed as possible, ensuring the best possible listening experience for the listener. In addition, your purchase will include two sets of grilles to suit your taste of either leather or carbon fiber!









The Sound of quality

Sonic Electronix, one of the leaders in car audio, recently visited Harman, the premium global audio and infotainment group, at their research and development locations in Northridge, California and Detroit, Michigan. The purpose of these visits was to utilize and combine the powerful brand of Harman and the industry leading knowledge behind Sonic Electronix to begin working together on developing future car audio projects.

Wow!

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.

JBL 660 GTi

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.

JBL 660GTi

Great speakers, I wish I could find midrange speakers with clear voice quality. These 660GTI's are more for bass..

great speakers

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 . Packaging ( Aluminum case ) is what makes these speakers so expensive . Cardboard box with Styrofoam would have sufficed . I do recommend the JBL 660 GTI
to anyone who is serious about mobile HI FI .
By playing Pink Floyd " Dark Side Of The Moon " is how I checked the performance of these speakers . Note : these speakers should be paired with a Sub Woofer to bring out the full potential .

When only the best is good enough for you

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. Nothing I have heard in this price compares. If you are looking at these, that means you like your sound. Pull the trigger and jump in!

JBL 660GTi

I've had these speakers in my Charger for over one year and have yet to find a system that sounds as good as it. One of the woofers went out with a bad voice coil and Sonic Electronix hooked me up with a replacement woofer. The clarity and seperation are superb. The only negative of having a audiophile quality system is that I can definitely hear how poorly some CDs are mastered. I am using the Pioneer Premier P800 PRS head unit and two Stage 4 PRS A900 amps. I have the speakers bi-amped and have the crossovers set in the neutral setting. I have been using JBL speakers exclusively since 1975.

Best speakers out!

Amazing speakers. I have had seven pairs of components and these by far are the best I have ever owned. I compete in car audio. No one will touch my scores with me running these speakers.

Incredible Sound!!!!

I had a pair of MB Quart 6.5 components in my vehicle that I thought sounded great but..... they lacked the umph that a speaker should have when you really wanted it. I heard about the 660GTi speakers from JBL and decided to give them a try. I'm utterly shocked at the sound quality they give out - even at loud volumes!! Absolutely zero distortion and amazing performance. After tweaking of amps and deck, I've never hear a speaker give out more than I expected!!! Well done JBL!!! Bit expensive, but still worth it in the end!!!

Wow!

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.
