Bluetooth - Built-in Bluetooth automatically reconnects to the last device. Stream your music library from your smartphone or MP3 player or use apps such as Spotify and Pandora. Amplified - The speakers are powered by a high-performance built-in class D amplifier. Weatherproof - The latest weatherproofing techniques have been utilized so that if the weather decides to be anything but sunny, you can keep on riding. The IPX5 rating ensures that! Auxiliary Input - A 3.5 mm aux-in connection is compatible with the audio output of iPods, iPhones, smartphones, and MP3 players.

It complements the whole structure of the speaker by allowing constant abuse where it is most needed, without the wear and tear.

Since high-frequency sound waves are very directional, a wider dispersion of the sound waves will give you a larger "sweet spot".
