The JBL Boombox is JBL's largest portable Bluetooth speaker. Thanks to the 2 large passive woofers on the side, the Boombox produces a low and powerful bass, providing a large space with your favorite music. Thanks to the 24-hour battery life and waterproof design, you can place the speaker outside without any worries. If you really want to party, connect several Boomboxes together. On the first Boombox. you use JBL Connect+ and on the Boombox 2, you use the PartyBoost function.
