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 built for life on the water and the trail. Its IPX67 waterproof rating means it handles full submersion, not just splash, and UV-treated materials throughout protect against the bleaching and degradation that kills ordinary speakers outdoors. The composite polypropylene cone and UV butyl rubber surround resist moisture and flex without losing their shape. The integrated 0.75" composite dome tweeter delivers high-frequency detail without adding height to the assembly. At just 1" of mounting depth, it fits spaces that 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 marine and powersports applications.
Three things that matter.
IPX67 Waterproof Rated
Certified to IPX67, so it handles 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. It fits flush into wake towers, thin cabin walls and tight vehicle panels where full-depth speakers won't go.
UV-Stabilised Materials Throughout
The polypropylene cone, butyl rubber surround, powder-coated stainless steel hardware and integrated composite grill are all UV-treated, so they resist sun damage across years outdoors.
