When Daniel Ballou began his search to develop a system that uses disregarded materials to create high-fidelity sound systems, he only needed to visit the local construction site to discover the perfect medium. Concrete. Yes, believe it or not concrete – with its low resonance and vibrating properties – served as the perfect building block to build high-quality stereo speakers.
Now, in order to put them together yourself, all you need is a pair of cinder blocks and you’re set to install the remaining electronics yourself. Each speaker set is sold as an assembly kit, complete with a pre-wired and pre-assembled front panel that includes a 5” driver, tweeter, crossover, and input jack. Also, the back panel includes all the hardware needed to help mount the finished product together and seal the panels to the cinder block. They’ve been in development for over a year now but are finally ready to release to the public, just in time to rock out in the new year. Available now for $150. [Purchase]
