Overview

The JL Audio 010-03276-00 is a 7.7-inch enclosed tower coaxial speaker system sold as a pair for boats that need sound that carries in open air (model M6-770ETXv3-Gw-C-GwGw). Each speaker is a 4 ohm load with 100 W RMS continuous power handling, and it is typically paired with an amplifier in the 40 to 200 W per-channel range.

This configuration comes in a gloss white enclosure with a gloss white trim ring and gloss white classic grille, finished with black tweeter mesh. The enclosure measures 7.70 in (196 mm) in diameter and 12.62 in (321 mm) deep, with an overall height of 8.74 in (222 mm) when you account for the clamp receiver.

Key features

• Pair of 7.7-inch enclosed coaxial tower speakers for mounting up high on a tower or other structure, with the option to surface mount when the hardware setup supports it
• 4 ohm nominal impedance with 100 W RMS continuous power handling; recommended amplifier power is 40 to 200 W per channel
• 45 Hz to 25 kHz frequency response with 91.0 dB efficiency (1 W at 1 m) for practical output in windy, open-water conditions
• Flying-lead speaker connections with 16 AWG wire, 10 ft per speaker, to make clean routing to an amp or distribution point easier
• Enclosed housing dimensions: 7.70 in diameter and 12.62 in depth; 8.74 in overall height including the clamp receiver
• Mounting clamps are required and sold separately, so you can match the hardware to your tower tubing and mounting layout
• Construction that exceeds international standards for salt fog and UV exposure for long-term use on open boats

Compatibility and fit

This is an enclosed tower-style speaker system intended for installations where the speakers sit above head level, such as wake towers, hardtops, T-tops, radar arches, and other tubular structures. It also supports surface-mount style installs when the chosen hardware and mounting surface allow for a secure, vibration-resistant fit.

Because the mounting clamps are not included, fit is determined by the mounting fixtures you select. Confirm the tubing diameter and available clearance before ordering clamps, and check that the speaker body depth and rotation will not interfere with canvas, lights, antennas, or tower folds.

Installation and setup

Plan your wire run from the tower to the amplifier before mounting. The speaker leads are 16 AWG and 10 ft long, which covers many tower-to-helm routes, but longer boats often benefit from junction points or extended runs using appropriately sized marine speaker cable.

Use drip loops and protected routing where the wire passes through tubing or near sharp edges. Once installed, seal any penetrations and secure the cable so it cannot chafe under vibration or when the tower is folded.

Electrical and amplifier notes

These speakers present a 4 ohm load, so verify your amplifier is stable at the wiring configuration you plan to use. If you are running multiple speakers per channel, map out the final impedance at the amp terminals before you commit to series or parallel wiring.

They are rated for 100 W RMS continuous handling per speaker, which helps when matching amplifier output and setting gain so the system plays cleanly without pushing the speakers into distortion.

Use cases on board

This setup makes sense for wake and surf boats, center consoles with a hardtop or T-top, and pontoons with a tower where passengers and riders need music that stays present in wind and engine noise. It is also a good match for owners upgrading from small pod speakers who want a larger 7.7-inch format in an enclosed housing while keeping mounting flexible through clamp selection.

Maintenance and care

Rinse with fresh water after saltwater runs and keep the grilles free of dried salt and sunscreen residue. If the boat is stored outdoors, a tower cover helps reduce long-term UV exposure on finished surfaces between trips.
