UV-stable cones
Cones and surrounds that won't fade, crack or warp under relentless coastal sun.
Marine-grade audio for boats, ski-boats, jet-skis and pontoons — UV-stable cones, corrosion-proof hardware and amps that shrug off the spray. We supply and fit the lot.
Salt, sun and spray destroy ordinary speakers. Everything we fit on the water is built to take it — and keep sounding good doing it.
Cones and surrounds that won't fade, crack or warp under relentless coastal sun.
Gaskets, seals and coatings keep moisture, rain and spray out of the works.
Stainless grilles and marine-grade fixings that beat the salt air for the long haul.
Amplifier boards sealed against humidity and salt air, mounted dry and wired to last.
Tinned, sealed wiring and battery setups that handle vibration and the wet environment.
Output matched and tuned to carry clearly over wind, engine and water.
We don't just install audio on boats — we engineer it for them. The focus is simple: marine-grade sound systems built to survive sun, salt and spray.
From weekend runabouts to full custom builds, we design audio that integrates seamlessly — without compromising the deck.
On the water
The core of any marine system — supplied as genuine, marine-grade product and installed to survive the deck.
Element Ready™ sound with built-in Color Optix™ RGB lighting. The mid-tier sweet spot — louder, clearer and brighter, still sealed against the elements.
The honest entry point — fully marine-grade 6.5" speakers built to shrug off water, salt and UV. A clean, reliable lift from tinny factory boat sound.
The best-tier 6.5" — crisp, powerful and bright enough to carry over wind and engines, with rich Color Optix™ RGB and full marine sealing.
Tight, punchy 10" low end that fits where space is tight. Dual 2Ω voice coil for flexible wiring, with Color Optix™ RGB around the cone.
Bigger cone, deeper bass — a 12" marine sub built for authoritative low end on the water, with a dual 2Ω voice coil and RGB Color Optix™ lighting.
A dedicated IPX6-rated monoblock to drive a marine sub hard. Fully weatherised power, sealed against direct water for chest-hitting bass that survives the deck.
Self-enclosed "can" speakers that bolt straight onto towers, roll bars and cages — no mounting surface needed. Color Optix™ RGB and Element Ready™ build.
The best-tier Moto-Can — enclosed 6.5" pods for towers and bars with louder, clearer output and vivid Color Optix™ RGB, sealed for sun, spray and salt.
The flagship tower speaker. An 8" horn-loaded design that throws sound right across open water to the wake, with full Color Optix™ RGB lighting.
