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

Harman Tour

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.

Speaker Specifications

Series
This is the manufacturer product line of speakers.
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" x 8" (also mounts in most 5" x 7" locations)
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.
2-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 Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
1"
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.
Honeycomb Laminate (HCL)
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Rubber
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
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.
2-1/4"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
4-9/16" x 7-3/16" 
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.
No

AWESOME HIGHS!

November 4, 2014

These speakers have the best tweeters of any speaker I have ever bought and I have had kicker, alpine, polk, RF, clarion, pioneer, and more. Such a clear crisp high it gave me goose bumps the first time a turned them up. I have a subwoofer so It doesn't rally mater to me but Bass is ok, About the same as my stock ford speakers but a little clearer. Fit right into my f250 door holes and the stock screw holes lined up to. After I listened to the pair I bought for the front I ordered two more for the back very happy.

Ford Ranger Supercab

September 13, 2013

I installed these speakers in the rear and they sound great. With the factory stereo they gave a lower tone sound than the factory fronts. The highs when comparing front to back were crisper in the back but when played loud the factory speakers seemed on par at the higher end. Bass was much of an improvement over factory.Where the speakers really shined is when I installed a JVC KW R500 double din stereo. It gave much more power that was needed for the JBL's to show their true colors. JBL rocks with crisp highs and decent bass to keep me happy.

Great speakers! Sound Awesome

March 18, 2013

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

JBL GTO8628 Awesome Speakers

September 29, 2012

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.

Quality Sound

March 1, 2011

As expected, the engineers at JBL have produced a very natural sounding speaker. These speakers have a balanced natural sound to them. When driven by a quality head unit and amp, these speakers can be driven hard while maintaining their sound integrity. The balanced design allows the listener to fine tune or tailor the sound to his or her preference. JBL produces some of the best drivers and speakers for live performance venues. They obviously engineer some of the best car audio speakers, too!

Big sound for a small speaker

October 19, 2010

Listed as a 6 x 8 speakers, but they truly are a 5 x 7 that fits original mounts. These speakers provide great bass response, the built in cross-overs and the adjustable tweeters make directing your sound correctly a breeze. I use a aftermarket Alpine with a 45 watt amp with Infinity 5 x 7 front and these GTO-8628 in the rear. Sonic's price made these speakers a no brainer.

for the price i couldnt beat it. decent bass responsce, mids were alittle muddy at high volumes, as with highs. a good head unit and amp should fix that hopefully. overall im happy with them, but i would get the 4 0r 5 way pioneers if i had to order again. id say middle of the road and price point for most, not awsome, deffinatly not bad. wayy better than stock :)

VERY accurate speakers for the price

April 27, 2010

these are very accurate speakers (as mentioned above)...
Woofer Review:
the bass response is tight...no distortion to speak of...at full volume with the bass i get punchy, tight sounds that really give the music more of home stereo feel (which is what i want)...the vocals are very strong and don't get distorted at high levels...

Tweeter Review:
The way that the tweeters are designed is very practical...on normal setups it seems that the crispy highs get driven right into my shins...to the point of not really noticing them..with these GTOs you can adjust the angle of the tweeter so that the sounds can be driven upwards towards the driver so the highs don't get lost in the bass....and the tweeters are really sweat...again no fuzz or distortion just crispy highs...

i have a amp on order for them, but really off of the head unit they are A1 components....I HIGHLY recommend these to budget shoppers and audiophiles alike...
