About the JL Audio M3-650X-S-GM

Alexander H.

Cool marine sound

Having toured JL Audio myself, I can tell you these guys take two things very seriously — great sound and life on the water. These M3-650X-S-Gm 6-1/2" marine speakers make both possible, thanks to excellent design and the most durable materials. You can mount them in your boat's cockpit or bulkhead walls, either as stand-alones or in conjunction with a subwoofer.

Cool marine sound

Having toured JL Audio myself, I can tell you these guys take two things very seriously — great sound and life on the water. These M3-650X-S-Gm 6-1/2" marine speakers make both possible, thanks to excellent design and the most durable materials. You can mount them in your boat's cockpit or bulkhead walls, either as stand-alones or in conjunction with a subwoofer.

Tough enough

Supplied with plenty of power, these speakers can overcome that wicked combination of wind, water, and engine noise. The weatherproof mica-filled polypropylene cone is suspended in a durable synthetic rubber surround for long excursion and impactful sound. The UV-resistant polymer basket surrounds and protects the entire structure.

The 3/4" treated silk dome tweeters deliver brilliant highs, and they're mounted directly to the gunmetal "sport" grilles for optimal sound radiation. Even in the roughest waters, you'll be able to enjoy the fine detail of your favorite tunes.

Product Research

Features

Marine Tested: JL Audio's marine speakers are tested in ultraviolet chambers to simulate years of sun exposure, and salt fog chambers to simulate years of exposure to salt-water environments.

Woofers: The woofer cones are injection-molded, mica-filled polypropylene with UV inhibitors, synthetic rubber surrounds, and marine-grade synthetic fiber spiders.

DMA (Dynamic Motor Analysis): DMA is JL Audio's proprietary method of improving dynamic motor behavior. The DMA-optimized long-excursion design enhances output, bass extension and power handling of the speaker.

Tweeters: Each speaker features a grille mounted ¾" treated silk dome tweeter with a specially formulated treatment to withstand the marine environment. The tweeters use neodymium magnets for higher efficiency levels and are Ferrofluid-cooled and damped for improved response and power handling capabilities.

Crossover: The woofers use a natural roll-off and the tweeter crossovers are 12 dB/octave. The crossover also features a polyswitch solid-state tweeter protection circuit.

Polymer Basket And Grille: The baskets and grilles are UV-resistant polymer. The baskets encapsulate the woofers' motor systems to prevent corrosion.

Infinite-Baffle Operation: The speakers are optimized for infinite-baffle operation so they can be installed in a variety of locations, without the need for a dedicated enclosure.

Power Handling: JL Audio recommends two RMS power figures for this model; 60 watts RMS continuous power handling and 20-120 recommended amplifier power. We've listed the more conservative 60 watts RMS in the specs table.

Q
Will the Jl mmr40 be sufficient to power these?
pauly d  Jul 19, 2023

A
The JL MMR40 will not, Paul. The MMR-40 is a wired marine remote control, and it actually has no onboard power amp or connections for speakers. It is very deceiving as appearance-wise it looks similar to the JL MediaMaster radios! If you choose the MediaMaster 50 in the first link below you can power the JL Audio M3-650X-S-GM's nicely! The speakers can handle 60-watts RMS so for peak performance and amp is needed, for great quality sound the MediaMaster 50 and JL speakers would be an excellent pairing! https://www.crutchfield.com/p_13699911/JL-Audio-MediaMaster-50.html

Thank you for your question, Paul. The JL Audio MMR-40 is a wired remote and not a receiver. https://www.crutchfield.com/I-rET1c195/p_13699911/JL-Audio-MediaMaster-50.html?tp=96441 The JL Audio MediaMaster 50 can be used with that remote and could power the speakers on the low end of their power handling. Those speakers would benefit from an outboard amp for best sound quality. I recommend reaching out to one of our Advisors at 1-800-324-9695 or by online chat, they'll be able to help with your new system.

Thanks for your question. For information on selecting the best amp for your speakers I would recommend reaching out to an advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system.

I know it's a couple of years late, but if anyone else has this same question, according to the JL website this speaker fits a 5"-5.25" diameter hole.
