7.5-Inch Waterproof Marine Speakers with Ultra-Shallow Mounting Depth

Aquatic AV’s 7.5-inch marine speakers are designed to deliver clear, full-range sound while fitting into very tight installation spaces. With a mounting depth of just 65 millimeters (approximately 2.6 inches), these speakers are specifically engineered for boats, personal watercraft, and other outdoor environments where shallow depth and durability are critical. Despite the compact profile, Aquatic AV says the speakers reproduce sound comparable to larger, deeper models, giving boat owners and installers the flexibility to upgrade audio without major modification to cabinetry or panels.

These two-way speakers are built from materials intended to withstand marine conditions. They are waterproof and treated to resist UV exposure and salt corrosion, which helps protect the components when mounted on open decks, rails, or other exposed locations. The two-way design provides separate handling of high and low frequencies for clearer vocals and better instrument definition, while the rated frequency response of 80 Hz to 20 kHz ensures reliable reproduction from low mids through the upper range of hearing.

Power handling is modest but suitable for most onboard audio systems: the speakers are rated for 100 watts maximum power output with a continuous (RMS) rating of 50 watts. That balance of peak and RMS power allows them to play cleanly at both moderate listening levels and louder settings without excessive distortion when paired with appropriately sized amplifiers. Stainless-steel mounting hardware is included for secure, long-lasting installation in corrosive marine environments.

For styling and installation preferences, Aquatic AV offers the speakers with two grill options: a classic white grill that blends into many boat interiors and a sporty silver grill for a more modern look. The choice lets owners match the speakers to existing dash and deck finishes. Pricing is listed at MSRP $119.99 for the white version and $149.99 for the silver sport-style grill.

These speakers are a practical choice for boat owners seeking improved sound quality without the need to rework panels or sacrifice deck space. The shallow 65 mm mounting requirement reduces installation complications, making it easier to replace factory speakers or add new zones in cabins, cockpits, or helm areas where back clearance is limited. Their marine-grade resistance to water, UV light, and salt spray also contributes to longer-term reliability compared with standard indoor speakers.

When considering these speakers for a system upgrade, match their power handling to your amplifier’s output to ensure the best performance and longevity. Because they are two-way units with a specified frequency range and RMS rating, they will perform best when paired with source units or amplifiers that provide clean power and, if possible, simple tonal control for better balance across the frequency spectrum.

Available from Aquatic AV in San Jose, California, these speakers are aimed at owners and installers who need compact, marine-rated solutions that don’t compromise on clarity.
