Detailed description

Designed for the marine environment, the JL Audio M3-770ETXv3-Sb-S-Gm-i marine tower speakers are a 7.7-inch (196 mm) coaxial system delivering powerful and clear sound reproduction. These 2-way speakers are optimized for tower applications, ensuring effective audio projection beyond the boat. They feature injection-molded polypropylene cones with mica reinforcement and synthetic rubber surrounds, paired with 19 mm (3/4 inch) silk dome tweeters.

Audio performance and marine durability

Each speaker delivers 70 watts RMS continuous power, with a recommended amplifier power of 20 to 140 watts RMS per channel. The system has a nominal impedance of 4 ohms and a frequency response of 45 Hz to 25,000 Hz (±3 dB), with a sensitivity of 90.5 dB at 1 W/1 m. The woofers are optimized using DMA technology to reduce distortion and improve bass quality. Second-order high-pass filters for the tweeter are integrated, along with a semiconductor protection circuit to minimize failure risks. The marine-grade construction includes UV- and corrosion-resistant polymer baskets and grilles, ensuring reliability in harsh marine environments.

Integrated RGB LED lighting and installation

The M3-770ETXv3-Sb-S-Gm-i models feature Sport grilles and include integrated multicolor RGB LED lighting, casting a light effect onto the woofer cone. These LEDs can be wired for individual colors or controlled via an optional RGB controller (sold separately) for an extended color palette. Installing these speakers requires JL Audio mounting hardware (sold separately) and allows adaptation to various pipe diameters or flush mounting on surfaces. Decorative aluminum caps with the logo are included and can be oriented according to the mounting application. Wiring connections for the LEDs are required at each speaker location for the lighting function. A fast-acting inline fuse must be installed at the power source end for each +12V yellow LED speaker connection. LED current draw is 108 mA at 12V DC, with a recommended fuse rating of 150 mA.

Expert opinion

« JL Audio M3-770ETXv3: sound power and lighting ambiance for marine towers »

The JL Audio M3-770ETXv3-Sb-S-Gm-i marine tower speakers are a targeted audio solution for recreational boats and water sports. Their design specifically for towers ensures efficient sound projection, essential for wakeboarders or water skiers to hear clearly even at a distance from the boat. The 70 W RMS nominal power per speaker, combined with a sensitivity of 90.5 dB, delivers sufficient volume with adequate amplification (20-140 W RMS per channel recommended).

The integration of RGB LED lighting is a notable aesthetic feature, allowing customization of the onboard lighting ambiance. It is crucial to plan the LED wiring carefully, including provision for an external RGB controller (such as JL Audio’s MLC-RW) to fully utilize color options, and above all, to follow fuse recommendations for circuit safety. Physical installation requires JL Audio’s specific mounting kits, sold separately, which ensure robust and secure integration onto the boat’s tower. The durability of the materials, tested against UV rays and saltwater, guarantees long-term performance in a marine environment.

Frequently Asked Questions

Need help? Contact us

What is the diameter of the M3-770ETXv3 marine speaker drivers?

The diameter of the speaker basket for these loudspeakers is 7.70 inches (196 mm).

What is the nominal impedance of the speaker system?

The nominal impedance of the system is 4Ω.

What is the frequency response range of these speakers?

The system's frequency response is 45 Hz to 25 kHz ± 3 dB.

What is the continuous RMS power per channel supported by these speakers?

The continuous RMS power per channel supported is 70 W.

What is the recommended RMS amplifier power per channel for the M3-770ETXv3?

The recommended RMS amplifier power per channel is 20 to 140 W.

What is the performance of the M3-770ETXv3 speaker system?

The system's efficiency is 90.5 dB at 1 W / 1 m.

Are these tower speakers equipped with LED lighting?

Yes, these speaker models are equipped with built-in multicolor RGB LEDs to produce vibrant accent lighting.

Which accessories are included with marine tower speakers?

Included accessories are: Two aluminium logo caps One tube of silicone adhesive Eight red crimp connectors (22-18 AWG) Four blue crimp connectors (16-14 AWG)

What type are these marine speakers?

These are marine tower speakers, a 7.7-inch (196 mm) coaxial system.

Are the mounting brackets included with the M3-770ETXv3 speakers?

No, JL Audio® mounting brackets are required and sold separately.

What type of fasteners are required to install these speakers?

Installing this product requires the use of JL Audio® mounting hardware (sold separately). No other installation method should be attempted.

Is it recommended to have the speakers professionally installed?

Yes, it is strongly recommended to have your enclosed speaker systems installed by your authorized JL Audio dealer. The installation professionals employed by your dealer have the tools and experience required to install this product correctly.

What are the important considerations for wiring LED lighting for speakers?

You must install an inline fast-acting fuse at the power source end of each YELLOW (+12V) LED wire of the speaker. Do not connect to 24V electrical systems. Do not connect the speaker LEDs to the vessel’s navigation lighting circuits. A minimum 16 AWG wire gauge is recommended for each speaker LED connection circuit. It is recommended to power the speaker LEDs via an interior/cabin lighting circuit that provides +12V through an existing switch, or to install a dedicated switch.

How can I get specific colors for the LED lighting on the speakers?

You can wire individual wires or a combination of wires to achieve up to seven different LED color combinations. For example, for red, connect the red wire; for green, the green wire; for blue, the blue wire; for yellow, the red and green wires; for pink, the red and blue wires; for aqua, the green and blue wires; and for white, the red, green, and blue wires. All YELLOW wires (+12V) must be combined (in parallel) and connected to a switched +12V power supply.

What fuse rating is recommended for the LED lighting of these speakers?

The recommended fuse rating for LED lighting is 150 mA.

What is the current draw of the LEDs on these speakers at 12V DC?

The current drawn by the 12V DC LEDs is 108 mA.

What is the voltage range for the LED lighting power supply?

The voltage range for powering the LED lighting is 10 to 14.4V DC.

Can I connect the LED lighting of the speakers to a 24V electrical system?

No, it is imperative not to connect LED lighting to 24V electrical systems. The power supply must be +12V.

Does attempting to remove the LEDs from the speakers void the warranty?

Yes, the LEDs are permanently mounted. Any attempt to remove them will cause damage not covered by the warranty.

How can I control the RGB LED lighting of my masthead speakers?

The JL Audio M3-770ETXv3-Sb-S-Gm-i marine tower speakers are equipped with built-in RGB LED lighting for vibrant accent lighting. There are two main methods to control this lighting:

Via an RGB lighting controller (sold separately): This is the recommended method for adjustable and customized color control. The JL Audio marine lighting controller (MLC-RW) is specifically recommended for optimal performance. When selecting a controller, ensure its output capacity is not exceeded by the total LED circuit amperage (each M3-770ETXv3 speaker consumes 108 mA at 12V DC). Direct wiring: You can wire individual wires or a combination of wires to achieve up to seven predefined LED color combinations.

For correct and safe installation of the LED lighting, consider the following points: A fast inline fuse must be installed at the power source end of each yellow (+12V) LED power wire of the speaker. A 150 mA fuse value is recommended for the M3-770ETXv3. Do not connect the LEDs to 24V electrical systems. Do not use the boat's navigation lighting circuits to power the speaker LED lights. A minimum 16AWG wire gauge is recommended for the LED connection circuits of each speaker. It is advisable to activate the LEDs via an existing cabin/interior lighting circuit providing +12V through a switch. If an existing switched circuit is not available, a dedicated rocker/toggle switch can be installed to provide positive (+12V) power.
