JBL Boombox 4 Portable Speaker

The most powerful portable unit in the range, built around two five-inch woofers and two three-quarter-inch tweeters working with three passive radiators that extend the response down to thirty-seven hertz. The construction replaces the single subwoofer used in the previous generation with two mid-range drivers and an additional radiator, which is what produces the broader low end. Rated output changes with the power source. On mains it delivers two sixty-five-watt RMS woofer channels and two forty-watt RMS tweeter channels, while on battery the woofer channels drop to sixty watts each. Playtime reaches twenty-eight hours on a single charge with a further six hours from the extended playtime mode, and the battery itself is user replaceable rather than sealed into the chassis. The unit carries an IP68 rating and offers two selectable bass modes, one tuned for depth and one for tighter punch, alongside lossless digital playback over USB-C and wireless pairing with other compatible units. KIC supplies, configures and supports it as part of the audio systems we deliver across Egypt.
