Think a portable speaker can't make the block rock? Meet the 200 W SumoBox Pro - it's a busker's dream. Bluetooth means no cabled connections necessary and, because its battery lasts up to 8 hours, you can get a full day's gigging done. Even the rain shouldn't put a dampener on your performance because this is IPX4 splashproof. Good to know - Battery died mid-gig? The show can go on - remove the battery and pop in a spare or switch to mains - SAM by Devialet improves low-frequency performance, so your bass lines are crisp and detailed as well as booming - True Wireless Stereo is as easy as pairing two of these SumoBox Pros together with Speaker Link - Every instrument in your band is catered for with the dual XLR/TRS combo inputs and one mic jack- The 3-Channel Pro Panel gives you independent level control for reverb, bass and more- It works as a power bank for your phone too - handy if you're on the street away from outlets- You don't have to just lay it on the ground - you can mount it on standard 35 mm speaker stands_________________________________________________________ Please note: One battery pack included, additional spare battery packs sold separately.
