In case you’ve seen weather-resistant speakers as well as weatherproof models and have no idea what’s the difference between them, then here’s an explanation. The weather-resistant rating is applied to speakers that might be able to hold well in humid environments and foggy weather, and they might also get away with being exposed to rain showers.
But being weather-resistant does not make them waterproof, and that means that they’ll likely get damaged if you leave them out in the rain for prolonged periods of time. Waterproof speakers, on the other hand, should be able to withstand even heavy rain so you can count on them in any kind of weather.
