Looks divine. Sounds delicious.

Head's are going to turn when they hear the sound that pumps through the JBL GX Series speakers. But get in and "whoa!" they look incredible. Designed to fit most factory specs, the GX series fl aunt a new HARMAN-proprietary tweeter deflector, they're individually voiced, and have three-ohm voice coils for optimal power distribution. Add Plus One woofer cones, edge-driven soft dome tweeters and an ogle-worthy design, and you've got a speaker that does much more than deliver killer sound.

Plus One Woofer Cones

Harman's patented (US patent #7,548,631) Plus One polypropylene cones provide more overall speaker-cone area than other cones in its class — the result is higher sensitivity, increased low frequency output and greater musical character.

Edge-Driven Soft Dome Tweeter

Soft dome tweeters deliver a smooth high-frequency response and an increased power handling for highs and mids, which equates to more lifelike sound from vocals, cymbals, brass instruments and pianos.

Frequency Response Up to 21kHz

Hear what you've been missing — the JBL GX Series offers a frequency response that delivers the full-range response associated with exceptional sound.

Affordable Pricing

The JBL GX Series are all designed to give audio enthusiasts more boom for the buck — while they maintain a conservative price point, there is never a compromise in sound.

Three-ohm DCR Voice Coils

The majority of factory-speaker wiring is so thin that it can't draw the necessary power for great sound. With low-impedance, three-ohm voice coils, the GX Series speakers can pull more power from the amplifier, which means a clearer, richer sound for the listener.

HARMAN-Proprietary Tweeter Deflector

Acting as a waveguide, the tweeter deflector allows for an angled, rotating speaker, which optimizes the off-axis sound performance. Because all cars are designed differently, this allows impeccable sound to travel throughout all locations in the cabin.

OEM-Level Reliability Testing

JBL tests every speaker design to the same rigid specifications as the automakers, subjecting them to extreme conditions that would break lesser speakers. We freeze them, bake them, shake them, blast them with ultraviolet light and drive them at full power for days to make sure your audio investment lasts for years.

Individually Voiced

For most brands, off-the-shelf speakers and a cursory approval of frequency response curves are good enough. That's not the case with JBL. We don't only listen to our speakers against the competition — we voice them against each other to ensure each line has the consistent JBL sound signature that's known and sought out by those who care about their audio. This is just part of an extensive development process undertaken by some of the best transducer engineers in the world to provide the finest listening experience at any price point.

Priced Per Pair

Speaker Specifications

This is the manufacturer product line of speakers.
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.
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.
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.
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.
Soft Dome
Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
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.

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.
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.
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
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.
2.3 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.

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.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches, required to contain the speaker.
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.

Great sound for the money

May 10, 2015

So, bought these to replace a pair of blown front speakers. They sound quite good for the money. When comparing to a pair of MB Quart 6.5" components I had in a previous car, these are better. The lows are quite good. Mids and highs are decent but those MB Quarts were a little better, however the lows on the MB Quarts were horrible due to plastic construction. The JBLs are steel and quite stout. Overall these are a much better speaker and I plan on buying a second pair along with an amp to really bring them to life.

Needs a hefty hand when EQ'ing, but pretty great then.

February 9, 2018

I bought these and the 5.25" variant to replace my door speakers. They are amped with a Class D Pioneer amplifier. On the other hand, with 14W from the head unit they are fairly easy to drive. Driven from a head-unit, distortion occurs before just before they get "roll down the windows" loud. Regardless of the sensitivity of these, an amp is recommended.

These are rated to go as low as 50 Hz, but there is an audible little bump at 45 Hz which is nice if you don't have a subwoofer. Not sure how noticeable it would be with road noise however. Then nothing until around 58 Hz. But even then, it doesn't really pick up it's full dB until 100 Hz. With an under the seat subwoofer and some clever crossover tinkering, it sounds great with a bit of sub support at 63 Hz to 100 Hz.

As you can tell above, these by no means follow a flat frequency response from 50 - 100 Hz. These frequency problem persists throughout. I EQ'd these with white noise and a sound pressure meter. Out of the box, these aren't gonna sound amazing. Bass is going to very uneven, vocals will be in a box, and treble will be a tad overbearing. 50 - 100 Hz is up and down very bad. Boost 80 Hz if you can with either EQ or subwoofer assistance.

Major vocal performance can be corrected, thankfully. There must be some kind of crossover in these between 800 Hz and 1.25 kHz that was designed by a lunatic. I had to up 800 Hz by 5 (!) dB and drop 1.2 kHz by 4 dB. Looking at a frequency spectrum of this area is hilarious. Again, not sure what they were thinking. Even with these corrections, vocals aren't perfect, but VERY much improved over stock. I also took down the 12.5 kHz range a bit. This frequency region is dependent on your hearing health though.

Sound great in my 2015 road glide.

December 11, 2016

I bought these speakers because I heard them and they had good low end. They fit right in my fairing of my road glide. I am just running them from the stock head unit and they are plenty loud. I did have to trim part of my speaker cover so it wouldn't touch the speaker. I am very pleased with them.

Good evening. In doing some research online I am wanting to upgrade the stereo system in my 1995 Acura Legend LS. It has the Bose premium system in it right now and I am fairly certain all of the speakers are toast. In my research the system is amplified and runs 2 ohm. I am looking for factory direct replacement speakers for the front and the back that are 2 ohm stable. What do you suggest I go with as I do not want to replace the headunit nor bypass the factory amp?
