Detailed description

Designed for the marine environment, the JL Audio M3-770ETXv3-Sb-S-Gm marine tower speakers are a 2-way 7.7-inch coaxial system optimized for clear and powerful sound. These speakers are housed in injection-molded enclosures with a satin black finish and equipped with sport gunmetal grilles.

Audio performance and marine robustness

The M3-770ETXv3 system features a mineral-injected polypropylene (MIPP) cone woofer with a synthetic rubber surround, paired with a 19 mm (3/4-inch) silk dome tweeter. It delivers 70 watts RMS continuous power per speaker and 225 watts peak power. The nominal impedance is 4 ohms, with a frequency response of 45 Hz to 25,000 Hz (± 3 dB) and an efficiency of 90.5 dB at 1 W/1 m. Passive 2-way crossover filters are integrated into the woofer baskets for optimal frequency separation.

The construction is specifically designed for harsh marine conditions, with UV- and corrosion-resistant polymer baskets and grilles. JL Audio subjects its products to UV chamber and salt spray testing to ensure durability. Lightweight neodymium magnets contribute to acoustic performance without affecting the boat’s center of gravity. Connections are made via gold-plated marine-grade brass terminals.

Integrated RGB LED lighting and installation

The sport grille frame incorporates an RGB LED lighting assembly that uniformly illuminates the woofer cone area. An optional RGB controller (sold separately) provides access to a wide range of colors. LED specifications include a current draw of 108 mA at 12V DC, with a recommended fuse rating of 150 mA and an operating voltage range of 10 to 14.4V DC. Installation requires JL Audio mounting hardware, sold separately. Speaker wiring exits through the center of the bracket for discreet integration. The product comes with a 2-year warranty.

Expert opinion

« Technical analysis of JL Audio M3-770ETXv3 tower speakers »

JL Audio M3-770ETXv3 tower speakers are specifically designed for applications where sound projection beyond the boat is critical, such as wakeboarding or water sports. Their acoustic design is optimized for these scenarios, ensuring clear and intelligible audio even at a distance. The integrated RGB LED lighting adds a customizable visual dimension, essential for onboard ambiance.

Installing these speakers requires the use of JL Audio’s dedicated mounting hardware, sold separately, which ensures a robust and secure integration on wake towers. The discreet routing of wiring through the center of the bracket contributes to a clean finish and minimizes exposure to the elements. The marine-grade construction, with UV- and corrosion-resistant materials, guarantees extended longevity in saltwater and humid environments—a key consideration for any marine equipment.

This model is a suitable choice for users seeking a high-performance, durable marine audio solution capable of withstanding harsh conditions while offering modern aesthetic features. Although installation requires careful attention due to multiple wiring runs (audio and LED) and dedicated mounting hardware, the end result is a seamlessly integrated and visually appealing audio system.

What are the wiring requirements for integrated LED lighting?

For wiring the LEDs, you must use:

A 16 AWG wire for the positive (+) and negative (–) of the speaker. 20 AWG wires for the RGB LEDs (red, green, blue) and the main positive wire (+12V) of the LEDs (yellow). A fast-acting fuse must be installed inline at the power source end of each yellow LED supply wire (+12V) of the speaker.

Can the LEDs be removed from the tower speakers?

No, the LEDs are permanently attached to the speakers. Attempting to remove them will cause damage not covered by the warranty.

What are the safety precautions for wiring LED lighting?

It is imperative to follow these precautions:

Do not connect the LEDs to 24V electrical systems.Do not connect the LED lights of the speakers to the boat's navigation lighting circuits.Install an inline fuse at the power source end of each yellow LED power wire (+12V).Use a wire of at least 16 AWG for the LED connection circuits of each speaker.

Should an LED lighting controller be used, or can the LEDs be wired directly?

Using an RGB lighting controller (sold separately) is recommended for adjustable LED control. Alternatively, you can wire individual wires or a combination of wires to achieve up to seven different LED colors. Refer to the controller’s instructions or the direct wiring diagram for specific connections.
