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.

Speaker Specifications

Series
GTO (JBL)
Priced Per
Car Speakers are typically sold in pairs so you will receive 2 speakers for each speaker purchase on speakers marked "Priced Per Pair". If a speaker is marked "Priced Per Each" then the speaker is sold individually and each purchase you make will result in 1 speaker. High-powered tweeters, midrange and full-range pro audio for car speakers are typically sold per each speaker.
Pair
Speaker Size
Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
6-1/2" (also mounts in 6-3/4" w/ included brackets)
Design
The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
3-way
Tweeter Design
Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.
Dome
Tweeter Composition
Materials such as polypropylene, silk, cloth, and paper are the most common, where as many more recent tweeters are now manufactured with composites such as Aluminum, Titanium, Mylar, and other materials.

PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.

Mylar/Titanium Hybrid
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Plus One
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
180 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
60 watts
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
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".
92 dB
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
50 - 21,000 Hz
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
2 ohms
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

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.

Yes
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
2"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
5-1/8" x 5-1/8" 
Speaker Grilles
A grating or screen of metal or plastic bars or wires, mounted in front of a speaker as protection. If yes, the speakers will include matching speaker grilles. If no, there are no grilles included.
Yes

Good speakers

September 9, 2010

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.

I would recommend these speakers for 2 reasons. I bought them without ever hearing them and they are a JBL product pretty much the only speakers I would ever own. If only Yamaha would now make car stereos the world would be a better place lol.

I purchased these as replacement door speakers in a 2001 Silverado. Perfect fit. With just the factory HU they sound great. The more power the better they sound. You will not be disappointed with these.

Great replacement for OE speakers

February 1, 2014

I bought the GTO 638 to replace rear door speakers in my 2006 Hyundai Tucson. I'm still using the factory head unit. These are a big improvement over the factory originals. Sound quality is much better. If and when I need a new head unit, I know I can depend on these speakers to handle it. I highly recommend these speakers and their price was reasonable. Pros: good sound quality Cons: None

Great sound

January 28, 2014

Great sounding speakers. Blows away the factory garbage. Factory speakers would distort at just over 3/4 volume. Needed more sound to compete with the pipes. Now I can hear the stereo over the pipes clearly. Don't forget the adapter rings when buying.

Get ready to rock

January 23, 2014

I have owned these speakers for about a month now. I received them from my wife as a xmas present. Found a youtube video on how to install them in my Chevy Impala. The speakers sound great. Tremendous high end. The only downside that I have found so far is that these speakers do tend to draw some power to drive them. I am driving them with the stock Chevy radio and they need more power. I can't wait to buy some JBL 6x9 inch speakers for the rear deck and a new radio to drive them. Then my system will really ROCK!

January 11, 2014

These are exactly what I expected from JBL with a very low price. At $55 the performance far exceeded the price. These were used as factory replacement front door speakers in a 2006 Impala and with the factory stereo, a JBL amp, and 2 6x9 JBL rear speakers. The system is amazing and the buying experience from sonic elec was awesome!! I will purchase from them again!

Pretty good on factory amp

December 19, 2013

I have a 2010 Chevy Avalanche with the "premium" Bose factory system which is not so premium. I needed a 2 ohm 6 1/2 or 6 3/4 speaker to replace my door speakers cause that's what came factory so I went with these. Bought 4 (2 pair) for all my doors. Man they sound loud and clear for being run only on the factory amp and head unit. I don't see a need to add an aftermarket amp at this point.

September 17, 2013

I have a 2000 Chrysler 300M (LX body) with Infinity II sound. This requires front door speakers that are 6 3/4", with 2 ohm resistance, and are expensive and hard to find. I used these JBL's and they bolted in with no hassles whatsoever. Sonic's pricing was very competitive, and delivery was fast, as promised.

JBL GTO638 vs polk audio dxi6500

April 17, 2013

I bought 2 pairs of these bad boys for my car. They sound awesome, great highs, enough of mids and you can get some low's but not too much. I have all 4 speakers hooked up to a 4 channel 1000 Watt amp at 125 rms for each channel. They are pretty loud when i set my volume at 15 when the radio can hold up to 50 on the radio. After 30 i get distortion. I'm really happy with my product and i do recommend these speakers and it will sound even sweeter with an amp. By the way i also own 2 pairs of the polk audio dxi6500 and i was disappointed how i spent more $$$ on them and they dont sound as good as these JBL. 2 tweeters went out on my polk audio's and i was stuck with only mids and horrible low's. they couldn't handle the power of the amp and it sounded lower than the JBL's.

recently bought these mated them to the same 5.25"'s and put them on a gto1004 from JBL... these sound (to me) better .. cleaner, deeper, all around than the 750$ focal's i was going to use. running them on 150W rms and they love it. for the money i couldn't ask for a better sounding speaker, keep up with the JBL 1224's i have running 1100 watts each! makes the BOSE system i had in my avalanche sound like childs play. thanks sonic for stocking a great product... huge jbl fan now
