Shakespeare HS-5A 5" Speaker Horn 15 Watts 4 Ohm

The Shakespeare HS-5A 5" Speaker Horn is a robust, weather-resistant public address solution designed for vehicle-mounted applications, marine installations, and outdoor communication systems. Built to withstand harsh environments and constant use, this 15-watt horn speaker delivers reliable audio projection for alert systems, announcements, and emergency notifications. Whether you're outfitting a work truck, emergency response vehicle, or marine vessel, the HS-5A provides cost-effective, durable audio output with genuine Shakespeare engineering backing decades of field-proven performance.

This speaker horn features durable weather-resistant plastic construction rated for sustained outdoor exposure, eliminating corrosion concerns common with metal-only designs. The 4-ohm impedance rating ensures compatibility with standard automotive PA systems and marine amplifiers, while 15 watts of output provides adequate volume for vehicle perimeter coverage without excessive power draw. Stainless steel hardware throughout resists rust and salt-air degradation, and the included adjustable plastic mounting bracket allows flexible installation angles on various vehicle structures. A generous 10-foot cable with heavy #20-gauge parallel construction delivers signal safely from your amplifier to the horn with minimal signal loss, even in RF-rich environments.

Technicians and fleet managers favor the HS-5A for police vehicles, fire trucks, tow rigs, and construction equipment requiring reliable exterior audio. The 5-inch speaker diameter balances directional projection with broad coverage—ideal for parking lot announcements, work-site warnings, and evacuation alerts. Installation requires only a 12-volt amplifier circuit (positive ground systems require polarity reversal), making retrofit integration straightforward on both vintage and modern vehicle electrical systems. The lightweight 4-pound design prevents excessive wind loading on antenna mounts or roof racks, while its compact footprint fits tight installation spaces common on specialized vehicles.
