JL Audio MX650-CCX

JL Audio 6½" MX-Series Marine Cockpit Coaxial System

MX-Series coaxial systems deliver excellent performance at a more affordable price than JL Audio's maximum-performance M-Series models.

CCX (Cockpit Coaxial) models have woofers specifically designed for infinite-baffle applications. This means that they are designed to operate without an enclosure. More specifically, the woofer design is optimized to operate with a large volume of air behind it (at least 2 cu. ft.). The bass response of the speaker will suffer significantly if placed in a small enclosure, so make sure your system is planned accordingly. The MX-Series is purpose-engineered and built for real marine duty and has been specifically designed to deliver maximum audio performance in any open-air boating environment. Although MX650-CCX Coaxial Systems can be used with as little as 20 W per channel, for best audio performance JL Audio recommends amplifiers capable of between 75 - 100 Watts of continuous power per channel, like the JL Audio M400/4.

0.75-inch pure silk dome tweeter

High Performance Highs

A 0.75-inch pure silk dome tweeter handles the high-frequency duties. Silk has been chosen for its lightness, excellent damping properties and smooth response characteristics that ultimately result in extremely transparent crisp audio. You will appreciate the clean, articulate high-frequency response of the MX-Series dome tweeter, especially at higher volume levels. The tweeter is specially treated to withstand the harsh marine environment, and is optimized to provide sound that will cut through even the most demanding of those marine environments.

True Marine Tested Design

True Marine Tested Design

Specifically engineered polymer baskets are corrosion and UV-resistant and encapsulate the woofer's motor system to prevent corrosion. Also, the injection-molded mica-filled polypropylene cone bodies with synthetic rubber surrounds, are specifically formulated with UV inhibitors for marine duty and the synthetic fiber spiders, with progressive roll designs, are optimized to withstand high humidity . JL Audio utilizes Ultraviolet testing chambers (to simulate years of sun exposure) and Salt Fog chambers (to simulate years of exposure to salt-water environments) to ensure that the MX-Series not only sound great in your boat, but will also sound great for many, many years.

Speaker Specifications

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.
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.
Injection Molded Polypropylene (IMPP)
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.
Synthetic Rubber
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".
89.5 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).
55 - 25,000 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.
4 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.
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.
Number of Speakers
This is the number of speaker that is included in the package. Each purchase will result in receiving the number of speakers indicated here. Please note that some items will have multiple woofers in the same enclosure. For sets of component speakers, this number will refer to the number of sets of speakers (For example, 2 would indicate the purchase includes 2 woofers and 2 tweeters).

Please refer to the product image and description for further details about the speaker.

MX650-CCX-CG-WH (White with Classic Grilles)

December 25, 2009

Speakers are at best OK, not as good as the older style Infinity 6.5 602M speakers I had before.

The JL's are high for the money and need an amplifier for any volume at all. I have heard the OTHER 6.5" JL speaker is better (NON "X" in MX)--if spending the money I'd recommend them over these.

Excellent price

May 19, 2012

These speakers are of some of the best quality that I have ever owned. I work in the field as a marine tech and I have always known that jl audio are for the most part the best speakers around. Now that I own them I can personally confirm that!

Great sound

October 21, 2012

Replacing Clarions that lasted over 5 years. The Clarion tweeters dry rotted, but the boat stays uncovered on saltwater year round. The mx650's have slightly more thump in bass, but otherwise basically same sound as Clarions. Not an exact bolt pattern match, but good enough where I didn't need any patchwork. Hoping to get same or longer use out of JL's. JL's have best grill available for a high performance speaker that looks great on a saltwater boat while not looking like it belongs on a 15 year old's wakeboard tower. Grill and speaker housing are built rugged and have withstood kicks and cooler bumps. So far after 6 months into it, this is a clear case of you get what you pay for, and I would definitely buy again.

Excellent marine option

May 25, 2012

Replaced the factory Clarions with these as part of a complete stereo makeover on a SeaRay sport yacht. Couldn't be happier. Solid and well built, rugged and dependable. In an open deck environment, the nuances of highs and lows are often lost, and I'm not the best audiophile, but the sound quality is vastly improved. A bit pricier than some alternatives, but they also have a reputation as the "go to" high end speakers for upscale marine environments so there is a little bit of admittedly shallow pride of ownership attached as well...and I don't have to defend a "no name great game" product.
