Polyplanar MB-41 White 10-watt 4 5/8" VHF Remote Speaker

The Polyplanar MB-41 White 10-watt 4 5/8" VHF Remote Speaker delivers professional-grade audio clarity in demanding tactical and maritime environments where communication integrity is non-negotiable. Designed for law enforcement, military, and commercial marine operations, this remote speaker extends VHF radio reach to secondary stations, console areas, or bridge stations where the primary radio unit cannot be optimally positioned. The white powder-coated marine-grade housing ensures corrosion resistance in salt-spray and high-humidity conditions, making it equally suitable for coastal operations, vessel deployments, or field command posts.

At 10 watts of output power, the Polyplanar MB-41 maintains intelligible voice reproduction across moderate distances without distortion—critical when tactical teams rely on split-second radio traffic to coordinate operations. The compact 4 5/8" form factor allows flush or surface mounting in confined spaces: vessel pilothouse cabins, emergency vehicle consoles, forward operating bases, or command shelters. Internal speaker design minimizes feedback and acoustic dead zones typical of small-diameter drivers, while the weatherproof construction seals out moisture, dust, and salt particulates that degrade audio fidelity over extended field duty cycles.

Field personnel—vessel captains, marine law enforcement, SAR coordinators, and tactical commanders—depend on remote speaker systems to extend radio coverage without installing multiple radio units. The Polyplanar MB-41 pairs with any standard VHF transceiver featuring remote speaker output, requiring only power and audio signal connections. Mounting brackets accommodate bulkhead or overhead installation; weatherproofed terminals accept 16-gauge speaker wire for cable runs up to 50 feet. Weight of approximately 2 lbs minimizes structural load on vessel frames, vehicle consoles, or field-portable equipment racks, making it ideal for weight-sensitive platforms including rescue boats, tactical vehicles, and modular command centers.
