A fully waterproof 6.5" coaxial built for the harshest marine and powersports environments, with a shallow 1" mounting depth that opens up installation options on wake towers, cabin walls and tight side-by-side panels.
The MBQuart Nautic Formula 6.5" 2-Way Coaxial Slim Fit speaker is engineered from the ground up for life on the water and the trail. An IPX67 waterproof rating means it handles full submersion, not just splash, while UV-treated materials throughout protect against the long-term bleaching and degradation that kills ordinary speakers in outdoor use. The composite polypropylene cone and UV butyl rubber surround resist moisture and flex without losing their shape, and the integrated 0.75" composite dome tweeter delivers high-frequency detail without adding height to the assembly. At just 1" of mounting depth, it slots into spaces that would rule out conventional marine speakers, making it a practical choice for LandCruiser 70 Series owners fitting audio to canopies, roof consoles or external panels alongside traditional marine and powersports applications.
Three things that matter.
IPX67 Waterproof Rated
Certified to IPX67, meaning the speaker withstands both dust ingress and temporary submersion, well beyond the splash-resistance of standard marine speakers.
Shallow 1" Mounting Depth
A 1" mounting depth is unusually slim for a 6.5" coaxial, allowing clean flush installation in wake towers, thin cabin walls and tight vehicle panels where full-depth speakers simply will not fit.
UV-Stabilised Materials Throughout
The polypropylene cone, butyl rubber surround, powder-coated stainless steel hardware and integrated composite grill are all UV-treated, resisting sun damage across years of outdoor exposure.
