JBL Boombox 4 delivers bigger, bolder JBL Pro Sound with deep, punchy bass that keeps the energy high wherever you go. Inside, two larger woofers, two tweeters and three passive radiators work together to give every track more impact and clarity. With intelligent AI Sound Boost analysing your music in real time, the speaker automatically optimises the sound for more power and less distortion – even at full volume. The refreshed design is larger yet lighter to carry, and with serious battery life plus full waterproof and dustproof protection, it’s built for parties that don’t quit.
