The Icom SP-37 is a high-output, heavy-duty external horn speaker and loudhailer manufactured by Icom Inc. in Japan. Purpose-built for commercial marine vessels, workboats, and exposed deck stations, the SP-37 projects loud, highly intelligible audio across long distances over ambient engine and wave noise when paired with compatible Icom marine transceivers equipped with public address or hailer functions.

Housed in a rugged, impact-resistant white ASA polymer horn enclosure, the speaker is engineered to withstand continuous saltwater exposure, extreme UV radiation, and heavy vibration. It includes an adjustable stainless steel mounting bracket for secure installation on mast spreaders, wheelhouse arches, or bridge wings.

Key Features:
• High-Output Audio Projection: Delivers powerful audio amplification for public address, intercom, and automated fog horn signaling across decks.
• Rugged Weatherproof Housing: Constructed from UV-resistant ASA polymer to prevent yellowing, cracking, or degradation under harsh marine conditions.
• Adjustable Stainless Steel Mount: Heavy-duty mounting bracket allows precise vertical and horizontal aiming of the sound beam.
• Sealed Voice Coil Design: Protected against moisture ingress, heavy spray, and driving rain encountered on open commercial decks.
