A New Standard in Portable Party Speakers
The JBL Boombox 4 arrives with serious upgrades: 210W output on AC, 180W on battery, and a seven-driver system including dual 5-inch woofers, dual 0.75-inch tweeters, and three passive radiators for booming bass and crisp highs. The AI Sound Boost tech intelligently adjusts the output in real-time, maintaining big sound with less distortion—even at full volume.
Smarter, Lighter, Greener
Despite a larger build, the Boombox 4 is nearly two pounds lighter than its predecessor, making it easier to carry on the go. JBL’s sustainability push is seen in its recycled grille fabric, eco packaging, and replaceable battery.
