Purpose-built for outdoor audio in demanding environments, the PQN ECO50-4BK gives you real speaker performance where weather, UV exposure, salt air, and humidity would destroy a conventional driver. Whether you're mounting them in a patio wall, under an awning overhang, in a wet bath, or on a pontoon deck, these 5-inch full-range speakers are certified for the conditions RV and marine owners actually deal with.
Most "weather-resistant" speakers tolerate light rain. The ECO50-4BK is engineered to survive full outdoor exposure. The cone is fully waterproof, the surround and basket resist UV degradation, and the speaker leads use silicone insulation -- the same type used in high-heat and wet environments -- to prevent corrosion-related shorts over years of use.
PQN designs these specifically for RV, marine, spa, and outdoor entertainment applications where the speaker may see direct water contact, salt spray, extended sun exposure, and temperature swings. The UL/ETL in-spa certification is not a marketing claim -- it means the speaker has been independently tested for immersion and wet-location use.
Fully sealed cone resists water intrusion, eliminating the warping and delamination that ends conventional outdoor speaker life.
Corrosion-proof silicone-insulated leads protect against shorts in wet, salty, and high-humidity environments for extended service life.
ASTM-certified for UV resistance and salt-spray exposure -- tested to the same standards as marine hardware.
Only 1.75 inches deep including the lens and 0.95 inches mounting depth -- fits flush in thin-wall RV panels and cabinetry.
The ECO50-4BK is the right choice for any location that sees moisture, sunlight, or salt air:
The ECO50-4BK carries a full set of certifications that matter for outdoor and marine audio:
The 5-inch diameter and shallow 0.95-inch mounting depth make the ECO50-4BK easy to fit in locations where a standard automotive or marine speaker won't clear. Mounting cutout diameter is standard for the 5-inch class -- typically around 4.375 inches, though confirm against your existing cutout or the template if cutting a new hole.
