These substantial bookshelf speakers from Taiwan’s 25togo feature cabinets made from concrete.
The cement and glass construction of the In Visible City speakers is said to project a powerful, clean sound profile. The compact speakers feature angled corners, which afford them flexibility in placement. However, I prefer the Engrish feature description from their website:
“Stereo Cubic presents the change of light shade by cube modeling, and the cutting declined surface not only presents thickness of stereo, but also allows more various and free placing ways available, and the concrete will make melodious music more vigoroso and steady to create a more comfortable and tasty private space for you.” Yum. Concrete never tasted so good.
The company recently showed a number of other cool contemporary household items at the 2007 Tokyo Designers Week show.
