Outdoor speakers that are meant to be permanently installed, such as mounted or garden styles, are typically designed to withstand the elements, including rain, snow, and hot summer temperatures. They’re constructed with weatherproof materials that won’t absorb water, so you also don’t have to worry about them cracking in colder temperatures. However, it’s still a good idea to install or position the speakers in areas where they’re covered by eaves or other structures for further protection.Smaller, wireless outdoor speakers usually aren’t fully weatherproof. They can withstand light rain showers, but these shouldn’t be left outdoors all winter.
