A:
While we do not recommend you place your outdoor speakers in the direct spray of garden sprinklers, intermittent or accidental exposure poses no problems either by design or historically. Some consideration should be made when considering prolonged exposure to pool or spa waters. These waters contain harsh chlorinated solvents particularly harmful to modern plastics and advanced materials. TIC exterior speakers are not underwater speakers and in that regard, technically, all such outdoor speakers must be referred to as "water-resistant" and not "water-proof".
TIC products are specifically designed to withstand water and while there are many stories of actual accidental submersion TIC outdoor speaker products continue to perform as designed.
