Compared with its popular predecessor, CUBE Street II is even lighter and more durable thanks to its modern ABS injection-molded design. The output power has been doubled too, giving you 10 total watts of crisp and clean stereo sound to cut through street traffic, train arrivals, and other noise challenges on the gig. In quieter situations where you don’t need as much headroom, kicking in Eco mode reduces the power to extend battery life.
