Premium marine audio engineered for Australian conditions — timeless classic styling meets serious offshore performance.
The JL Audio M3 6.5" marine speakers with white classic grille deliver professional-grade sound quality in a clean, traditional design built for harsh saltwater environments. Engineered with injection-moulded mica-filled polypropylene cones and 19mm silk dome tweeters, these coaxial speakers handle 60W RMS continuous power with 89.5 dB sensitivity across a 55 Hz-25 kHz frequency range. The white classic grille provides UV-resistant protection with a low-profile aesthetic, while stainless steel mounting hardware ensures long-term reliability in Australian coastal conditions. Ideal for boats, personal watercraft, and marine applications where clean aesthetics and audio performance matter without RGB lighting complexity.
Corrosion-Resistant Marine Construction: Mica-filled polypropylene cones and stainless steel hardware withstand constant saltwater exposure, UV radiation, and temperature extremes common in Australian coastal waters, offshore fishing grounds, and extended blue-water cruising.
Classic Grille Design: Low-profile white classic grille with 25mm protrusion provides UV-resistant protection while maintaining a traditional, understated aesthetic perfect for classic boat styling or professional commercial vessel applications.
Wide Frequency Response: 55 Hz-25 kHz range delivers clear vocal reproduction and extended bass response critical for cutting through engine noise, wind, and water splash during high-speed cruising, offshore work, or coastal navigation.
Efficient Power Handling: 60W RMS rating with 89.5 dB sensitivity means strong output from moderate amplifier power (20-120W recommended), preserving battery capacity during extended trips away from shore power or multi-day fishing expeditions.
Universal Mounting Compatibility: 127-133mm mounting hole range fits standard 5"-5.25" marine speaker cutouts in fibreglass consoles, hardtops, and tower enclosures without custom fabrication, oversized mounting rings, or dashboard modifications.
Silk Dome Tweeter Design: 19mm soft dome provides smooth high-frequency extension without the harshness common in metal tweeters, reducing listening fatigue during long fishing runs, multi-day coastal cruising, or extended offshore passages.

Will these speakers fit my existing 6.5" marine speaker cutouts?
These speakers accommodate 127-133mm (5.00"-5.25") mounting holes with a 156mm bolt circle, fitting most standard marine speaker installations without modification.
How much amplifier power do I need to drive these speakers?
JL Audio recommends 20-120W RMS per channel with the 60W RMS rating providing optimal performance around 40-80W from a quality marine amplifier.
Do these classic grille speakers have LED lighting?
No, LED lighting is only available on JL Audio M3 Sport models—these white classic grille speakers focus on traditional aesthetics without RGB illumination.
What mounting depth clearance is required behind the speaker?
You'll need 71mm clearance behind the mounting surface, with the speaker requiring 95mm total depth including the 25mm frontal grille protrusion.
Can these speakers handle full saltwater immersion?
While marine-grade and corrosion-resistant, these speakers are designed for splash-resistant mounting locations, not continuous submersion—install in cockpit areas protected from direct water pooling.
