Portable and powerfulWhen I tried out the Kicker Bullfrog BF100 I was impressed by two things — its compact size and its outsized sound. This portable Bluetooth speaker is about the size of a quart container of milk. The tough BF100 is both water- and dust-proof. It's great for outdoor adventures.360° soundThe BF100 features two 1-5/8" full-range speakers with two 2/58" passive radiators for enhanced bass. One speaker/radiator pair faces front, and the other faces rear, generating a 360° soundfield. No matter where I was in the yard, the speaker sounded great.Waterproof casingThe BF100's casing has an IP67 rating, meaning it's waterproof and dust-proof. In fact, it's designed to float on the water's surface. So enjoy your tunes at the beach, on the slopes, or by the pool worry-free. And if your BF100 gets splattered with dirt or mud, you can just hose it off.Kicker Connect AppDownload Kicker's free control app to your Apple® or Android™ device and really take control of your BF100.
