Powerful Performance for Marine Communication

Engineered for the demanding marine environment, the Newmar PA-40/30 hailer horn delivers crystal-clear audio projection even in rough seas. Its robust design ensures reliable operation for essential onboard communications, whether you're issuing safety announcements, signaling in fog, or activating alarms. With a high-efficiency driver and optimized horn shape, this 8-ohm unit cuts through wind and wave noise, providing distortion-free sound up to impressive distances.

Key Features and Build Quality

• Waterproof Construction: Fully sealed high-impact plastic housing withstands constant exposure to saltwater spray, rain, and humidity, meeting rigorous marine standards.
• Stainless Steel Hardware: Corrosion-resistant fasteners and brackets ensure long-term durability without rust or degradation.
• Compact Yet Potent: Measures approximately 11 inches wide, 6.75 inches high, and 8.3 inches long, with a stable 3-inch round base for secure mounting on decks, rails, or bulkheads.
• Versatile Impedance: 8-ohm rating pairs seamlessly with standard marine PA amplifiers for maximum power transfer and efficiency.
• Nominal 30 Watts / Peak 40 Watts: Handles sustained output without overheating, ideal for extended use in critical situations.

Ideal Applications Onboard

Boat operators, commercial vessel captains, and yacht crews rely on this hailer horn for a range of scenarios. Use it as a primary fog signal to alert nearby vessels, a public address system for crew instructions during maneuvers, or an integral part of alarm setups for man-overboard or fire alerts. Its talk-back compatibility in similar models extends to interactive systems, making it a staple in professional setups.

Recreational boaters appreciate its simplicity for weekend outings, while fishing charters and dive boats value the loud, intelligible hailing for coordinating with tenders or swimmers. Pair it with multi-channel PA systems for zoned announcements across larger vessels.

Installation and Maintenance Tips

Mounting is straightforward with pre-drilled holes and included hardware—secure to any flat surface using marine-grade sealants for added waterproofing. Connect to your amplifier via standard speaker wire, ensuring polarity matches for optimal phase alignment. Position facing forward or downward to direct sound effectively.

For longevity, rinse with fresh water after saltwater exposure and inspect hardware seasonally. Avoid obstructing the horn mouth to maintain peak performance. In high-wind areas, reinforce mounting points to prevent vibration-induced loosening.

Why It Stands Out Among Hailer Horns

Unlike flimsy consumer-grade speakers that falter in marine conditions, the PA-40/30 combines commercial-grade power with user-friendly design. It outperforms lower-wattage options in crowded anchorages or noisy harbors, yet remains lightweight at under typical bulkier models. Mariners report superior clarity over traditional air horns, especially for voice reproduction, reducing miscommunications that could lead to hazards.
