It’s important to remember, that even though the industry tends to use "waterproof" and "water-resistant" as interchangeable terms, even speakers with a high IP rating will have a limit to which their waterproofing can’t fully be guaranteed. While an IPX8 speaker has been lab tested to greater depths of submersion over longer periods of time, there is a cutoff point at which the testing hasn’t been guaranteed. Every speaker on this list has basic water resistance, which should be enough for splash and precipitation protection, but it’s advised to be careful around chlorinated or salt water.
