Icom SP37 Speaker Horn

The Icom SP37 Speaker Horn is a dedicated external speaker accessory engineered for professional two-way radio operators who require enhanced audio projection and clarity in high-noise environments. This speaker horn pairs seamlessly with the Icom M605 marine radio, making it an essential component for vessel communications, emergency response coordination, and commercial maritime operations. By directing sound output at focused angles, the SP37 delivers intelligible voice transmission without requiring constant radio volume increases that can distract or fatigue operators during extended shifts.

This speaker horn features a purpose-built acoustic design that amplifies mid-range frequencies critical to voice intelligibility while minimizing feedback and distortion. The construction withstands marine environments, accommodating salt spray, moisture, and temperature fluctuations common aboard vessels. Weighing just 2 pounds, the SP37 remains portable and easy to mount in wheelhouses, bridge areas, or emergency command centers without adding significant bulk to radio installations. The horn's external configuration allows operators to position audio output away from the radio unit, improving ergonomics and reducing operator fatigue during extended communication sessions.

The Icom SP37 Speaker Horn is ideal for maritime professionals, commercial fishing operations, search-and-rescue teams, and vessel captains who depend on reliable, clear communications in challenging acoustic conditions. Installation with the M605 radio is straightforward, requiring minimal technical knowledge while delivering immediate improvements in audio presence and clarity. Operators working in engine rooms, open deck areas, or other high-ambient-noise environments will particularly benefit from the focused sound projection, ensuring critical messages are heard without radio volume adjustments that compromise message quality.
