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.

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.

Have already replaced these speakers as they blew shortly after being installed. They were professionally installed and were not hooked up to too much power. I don't believe these speakers are not rated properly as far as the power they can handle.
