Description

Professional JBL Sound:

With the long history of professional audio equipment manufactured my JBL, it is no surprise that the Grand Touring Series (GTO) produce some of the finest sound available for car speakers. By integrating the majority of JBL's top car speaker technology, these speakers are able to effectively deliver truly stunning audio, while keeping the price affordable for everyone. For those that are looking for a quality car speaker that will not only sound great, but also keep more money in your pockets. Put your trust in JBL and these Grand Touring Series speakers.

Tweeter-Level Adjustment with Unipoint:

The tweeters on the GTO series speakers are an excellent example of JBL's advanced technology. Made from My/Ti (Mylar and Titanium composite), the tweeters offer a higher power handling, greater efficiency, and reduced distortion. To direct that sound where you want, JBL has designed a Unipoint rotating tweeter pod that allows the tweeter to be directed towards the listener. This results is better imaging and a more accurate sound stage. To top of the tweeter technology, JBL engineered a tweeter-level control switch that adjusts the tweeter dB output. This allows for more sound adjustments after the speaker is installed.



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.

Great Service -Fast Delivery - Well Packaged

Pleased with the product and the price is great in comparison to other sites.

Good speakers

Bought these to drive off HU and was not happy. Decided to put in rear and put CDT coax in front and drive with Kenwood 4 ch. amp. Well once I drove them with amp I discovered why I did not like running off HU. They are power hungry and once I had enough power to them combined with CDT's in front they sound unreal! I have always liked JBL and continue to like them. Just make sure you drive these with amp and give them the juice they need. If you do this they will perform.

Nice Speaker, Just feed it some power to be happy.

I got this speaker to replace the cheap 2ohm rear speakers in my 2014 Nissan Frontier. Install was very easy, but had to cut factory wiring to connect. Make sure you get the polarity right so you do not have to remove the door panel again. Sound it very nice with factory radio, But add a amp like i did and you will be much happier.

Great Upgrade

I bought 2 pair of these to go in my 2010 Chevy Avalanche to replace the "premium" Bose speakers in the doors. I was told I needed 2ohm speakers if I panned on using the factory head unit because that's what the factory speakers were. So I tried them and they sound amazing. Much better than those Bose speakers. I will eventually put an amp to them in the future but for now the head unit is doing a good job and these speakers really made the music come alive.
