Poly-Planar MA-840 80 Watt Subcompact Box Speaker - Black

The Poly-Planar MA-840 80 Watt Subcompact Box Speaker in Black is a compact, high-output audio solution engineered for maritime, mobile, and field deployment scenarios where space is limited but audio quality cannot be compromised. Built to withstand harsh environmental conditions, this 80-watt subcompact box speaker delivers clear, reliable sound reproduction in demanding operational environments where standard equipment would fail or prove impractical.

The MA-840's ultra-low magnetic field design is critical for operators working around navigation equipment. Unlike conventional speakers that generate electromagnetic interference, this speaker can be mounted in proximity to compasses, autopilots, and other sensitive instruments without degrading their accuracy—a specification that matters in marine operations, aerospace environments, and any setting where directional equipment must remain reliable. The speaker's rugged construction features polypropylene cones for acoustic integrity, corrosion-resistant stainless steel grills and brackets, and heavy-duty ABS enclosures that resist water intrusion and environmental degradation. These materials ensure durability in saltwater, humid, and extreme-temperature applications where standard speakers deteriorate rapidly.

This speaker is purpose-built for marine vessels, offshore platforms, field command stations, armored vehicles, and any installation where compact form factor and electromagnetic compatibility are non-negotiable. The 5 x 5 x 9-inch dimensions allow mounting in confined spaces—equipment racks, bulkheads, vehicle interiors, or enclosed communication stations—while the lightweight 2.6-pound design simplifies installation and minimizes structural load. The 80-watt output provides sufficient volume for crew communications and audio playback in high-noise environments without requiring external amplification beyond what standard marine or mobile systems already provide.
