These are simply hands down the best little speakers I've heard. They're unparalleled in fidelity, both treble and bass, even at very high volumes. They provide more bass, in fact, than I thought little 5-1/4's could. I'm more a treble guy though as classic rock is my forte and no doubt they deliver. Especially considering the price, they're a no brainer purchase. You will like the way it sounds. I guarantee it.
5-1/4" 2-Way GTO Grand Touring Series Coaxial Car Speakers
Professional JBL Sound: GTO528
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.

Priced Per Pair
PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.
Please refer to the product image and description for further details about the speaker.

I bought these speakers for the rear of my single cab ram 1500. Sound quality is pretty good, but are drownded out by front 6x9 in doors. May be a better speaker in a different location or setup.

This is the second pair of speakers besides the GTO938 I bought and mounted in a friend's truck. Sounds really good for the price but again I don't see any reason for putting a 0dB / -3dB switch for the tweeter since you'll equalize from the source in a much finer manner.

I am using these as a rear fill. I have them amped (80rms) and crossed over at 100hz. I originally tried 80hz, but they distorted a little bit at loud volumes. From 100hz and above, these speakers sound good. They are an excellent value.

These JBL speakers are a significant improvement over the stock speakers I had in my Ford Transit Connect. The sound is clearer and cleaner, musical instruments sound better, bass is much improved. The speakers do get a little screamy at very high volume, but otherwise I'm very happy.

I like them and can't hear the sound for the price. Installed in a civic hatchback and definitely boosted the driving experience! Sounds is a lot better than my Kenwood in my other Civic.

JBL is an excellent choice for any speaker demands and I chose these to complement my Infinity 6x9 that I installed in the rear of my Grand Prix with a new Kenwood Headset. Excellent sound quality all round!

I used these to re-place my front speakers in my Can-Am Spyder motorcycle. Since they are 2 ohm speakers they have effectively doubled the power of my head unit ( which is stock and cannot be replaced ). I can now play music quite loud if I choose to ( sometimes necessary on a MTC. ) without loss of clarity.

Purchased these speakers for my rear speaker pods on my 2012 HD Road glide ultra, when installing determined I needed some speaker extensions to push them out some due to the magnet size. Ended up creating my own to make it work. Speakers sound great.
