Built for the punishment of outdoor and marine environments, the PQN ECO50-4W delivers clean audio where standard speakers fail. Corrosion-proof silicone leads, waterproof cone construction, and UV and salt-spray resistance make these the right call for exterior RV bays, wet baths, patio walls, and boat cockpits alike. Meets ETL in-spa, RoHS, CE, and ASTM UV and salt-spray certifications -- not just marketing language.
Most consumer speakers deteriorate fast when exposed to humidity, UV radiation, road vibration, and salt air. The ECO50-4W was engineered specifically to resist those conditions. The cone and surround use waterproof materials that won't bubble, crack, or warp from moisture intrusion, and the speaker leads are silicone-insulated to resist corrosion-related shorts over time.
Whether you are installing these in an RV exterior entertainment bay, on a covered patio wall, in a marine cockpit, or in a high-humidity wet bath or sauna, these speakers are rated and certified for those environments. The 4.5-inch cutout diameter fits common enclosures and most factory RV speaker openings in the 5-inch class.
Cone and surround materials resist water intrusion -- no warp, no bubble, no deterioration in wet environments including spray-down and rain exposure.
Corrosion-proof silicone-insulated leads prevent oxidation-related shorts and maintain reliable connection in salt air and humid conditions over extended use.
ETL in-spa certified, RoHS and CE compliant, ASTM certified for UV and salt spray -- tested to real environmental standards, not just splash-resistant marketing claims.
Only 1.75 inches overall depth including lens, with a 0.95-inch mounting depth -- fits shallow bays and thin wall panels where full-depth speakers won't clear.
These are a straightforward drop-in for any 5-inch speaker opening with a 4.5-inch cutout. The mounting hole center-to-center spacing is 5.25 inches, which aligns with common factory RV and marine speaker mounting templates. Overall speaker diameter is 5 inches.
Connect to any standard 4-ohm compatible head unit or amplifier channel. The 30-watt max power handling is suitable for most RV stereo receivers and compact marine amps. Use appropriate 16- or 18-gauge outdoor-rated speaker wire for exterior runs.
PQN Enterprises backs the ECO50-4W with a limited 1-year manufacturer warranty against defects in materials and workmanship.
