The all-new JBL Boombox 4 is bigger, bolder, & better than ever, with powerful JBL Pro Sound that stays loud & clear, with deep thumping bass. AI Sound Boost analyzes our music in real time & adjusts the sound to give us more power with less distortion, even when we turn it all the way up. It packs two bigger woofers, two tweeters & three passive radiators, so every track hits harder & sounds cleaner. When we want to fine-tune the vibe, we just switch between deep or vibrant punchy Bass Boost settings to match our mood. We gave the classic Boombox design a fresh upgradeit's larger but lighter, so we can take it wherever the party goes: the beach, the block, or the backyard. It's IP68 waterproof & dustproof, so weather's never a dealbreaker. Material: Recycled Plastic, Fabric. Complies with Prop 65. 10" W x 21" L x 14" H
