I really like Sonic's customer service. That's what's lacking in many businesses world wide. Treat the customer like they are number one and give them fair prices. Also the shipping speed with this company is lightning fast as far as shipping speed goes.

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.

These speakers are great! I ordered them because they were the stock size for my 98 mustang, and I they seemed higher quality than most other. The rotating tweeter is great, and the woofer is able to handle some pretty good base. Because of these speakers, I actually decided to buy more JBL speakers for the back (I went with GTO938 speakers which were 6x9) Together they sound awesome



Really no downside to these speakers, they're just great. Only thing I'd consider replacing them with would be a JBL Component set

These speakers rock. The bass sounds great, mids and highs all sound great. These replaced some 4x6 speakers in a 04 silverado ext cab with a little trimming and use of the provided spacer between the spkr and door metal The difference is amazing. I would recommend these to anyone looking to improve the sound in there vehicle.
