Designer Daniel Ballou and industrial design studio Dashdot have teamed up to bring us a cool speaker pack that ships flat but pre-loaded with sound equipment. All you have to do is round up a cinder block and you’re in business. The pre-wired front panel includes a 5 in. driver, tweeter, crossover, and input jack. The back panel is a simple solid piece that comes with hardware to mount through the cinder block you bought for a buck or snagged from the construction debris down the street. The concrete block is great for low resonance and vibration minimization. Very clever concept. They’re expecting a retail price to be $150.
