We’ve only heard that loud sound shatters glass, so how about speakers made entirely out of glass? The first of its kind Greensound glass speakers are an absolute marvel to watch and own. The highly unusual Serac towering speakers inspired by an ice glacier produce 360-degree audio from a flat glass tower. The glass towers are sturdy enough to withstand 25 watts of power and offer 300Hz-15 kHz frequency range. The speakers are available in a variety of configurations including even a glass-encased subwoofer. Dope shit.
