Why Choose the Furrion FMS5B Outdoor Speaker?
Most outdoor speakers fail within a season — cracked cones from UV exposure, corroded internals from moisture, or distorted audio from road vibration. The Furrion FMS5B outdoor marine speaker is engineered specifically to eliminate all three failure points.
Its polypropylene-reinforced cone controls rigidity and internal damping, delivering clean, high-definition audio even at high volumes. The IP55 waterproof rating means it can handle full rain storms, not just light mist. And with ClimateSmart™ and VibrationSmart™ technologies, this speaker is purpose-built for the demanding conditions of RV travel and marine use.
The Furrion FMS5B outdoor speaker is the OEM replacement part — not a generic aftermarket substitute — ensuring a perfect fit and factory-matched performance.
