JBL Boombox 4 (Squad), Cinefolks

Inside the Boombox 4 sit two 123 mm woofers, two 20 mm tweeters and three passive radiators — two circular, one racetrack — in a 5.89 kg cabinet with a carrying handle across the top. It is a large portable built for beaches, gardens and worksites where mains power is not close by, and where a small speaker simply will not carry far enough.

On AC power the amplifier delivers 2 x 65 W RMS to the woofers and 2 x 40 W RMS to the tweeters, easing to 2 x 60 W on battery; response extends to 37 Hz. Three hours of charging yields up to 28 hours plus 6 more with playtime boost, and the battery pack is replaceable. Bluetooth 5.4 and Auracast handle multi-speaker linking.
