The JBL Boombox 3 is JBL's largest and loudest portable Bluetooth speaker, generating an enormous 80-watt output from four woofers and two tweeters that combine to produce ground-shaking bass and crystal-clear highs. IP67-rated for full waterproof and dustproof protection, it runs for up to 24 hours on a single charge and doubles as a power bank for device charging. The carry handle makes it portable despite its commanding size, and PartyBoost lets you connect multiple JBL speakers for venue-filling sound. An ideal product for event planners, outdoor entertainment businesses, and customers who want the biggest JBL experience.
