DemerBox is designed to withstand any outdoor environment - water, rain, hail, dust, sand, heat, snow. This room can be charged for more than 40 hours. Let you charge at any time, no matter the outdoor adventure! The founder Demer wants a good sound system that won't be damaged in transit or damaged in bad weather. So he drilled a few holes in the Pelican cabinet (Pelican cabinet is a high-end storage box widely used in the film and television industry to protect gears), screwed into some old speakers, and made the first one DemerBox. In 2014, Demer raised more than $80,000 on the crowdfunding site Kickstarter to mass produce the product. With more than 20 years of professional mixing experience and Zach's amazing talent as a tour and record manager, they come together to introduce this store to more audiences while still proudly handcrafting each DemerBox in the US.
