When we think of premium speaker materials, we don’t typically consider sand among them. But that’s what sets Deeptime’s Spirula speakers apart from the rest. Touted as “The World’s First Speakers Made From Sand”, these 3D printed speakers are practically from the future. Built from Silica Sand and aluminum, the Spirula Speakers are heavy on style and superior in function — definitely the type of speakers you’d write home about. Weighing in at just 2.4 kg, these babies are powerful enough to deliver killer sound and sleek enough to serve as the perfect décor for your pad. Is there any better combination?
