right.
A shallow-mount, IPX67-rated 6.5" coaxial built to handle salt spray, UV exposure and the rigours of Australian marine and powersports environments without compromise.
The MBQuart Nautic Formula 6.5" 2-Way Coaxial Slim Fit speaker suits installs where space and weather both work against you. Its 1" mounting depth opens up wake towers, cabin walls and side-by-side panels that would reject a conventional speaker outright. The composite polypropylene cone and UV butyl rubber surround resist moisture and sun degradation, and an IPX67 rating means the driver can handle full submersion at depth, not just a splash. Stainless steel hardware and a weather-resistant powder-coated frame round out a build made to stay looking and sounding clean season after season. It's rated to 40 watts RMS, meets the CEA-426B standard, and pairs reliably with factory and aftermarket head units alike.
Three things that matter.
IPX67 Full Submersion Rating
Certified to IPX67, this speaker handles dust ingress and temporary submersion, so it genuinely suits marine decks, wake towers and powersports vehicles that see serious water exposure.
1" Slim Mounting Depth
At just 1 inch deep with a 5-inch cutout, the Nautic Formula fits flush into tight cavities that rule out standard-depth speakers, including thin fibreglass panels and pre-fabricated tower pods.
UV-Treated Composite Grill and Surround
Both the integrated composite grill and the butyl rubber surround are UV-treated, so they resist the bleaching and cracking Australian sun inflicts on lesser marine speakers over time.
