No, but it really can't hurt. Even if you're not planning on taking your speaker out by the pool during the summer, it's not out of the question that it could be a target for spills no matter where you have it in your home. It would be a shame if a rogue glass of water ended up being the demise of your brand-new speaker, so if you have the option to go waterproof, do it (unless you have your heart set on one that doesn't have that feature).
