The Concretus by designer Gražina Bočkutė from Lithuania is an excellent speaker that is made from concrete! It may seem to be an odd choice of material, but its uniqueness rests in that very fact. Concrete in itself is a material with flaws, but it provides a larger sense of aesthetics, making each product unusual in a way because each speaker has a separate surface finish, different air bubbles in different places. The controls are made out of metal, standing out like a diamond among the dirt. The Concretus boasts of a clean, yet rough exterior, and a design that is too surprisingly calming to forget.
