This isn’t a Space Odyssey’s monolith replica, but an enormous iPhone speaker. Probably one of the largest and the most powerful in the world. If you’re among the people who believe that music should be enjoyed loudly, WOS 2.0 is definitely the speaker to pull the trigger on. This insultingly powerful hand-made monster comes with a couple of mighty subwoofers and a maximum power of 125 Watts that can be controlled via a custom iPhone app. WOS 2.0 weighs in at 178 kg, its 100cm in height and 170cm in width. The largest iPhone speaker in the world is available for pre-orders at indiegogo.com at a hefty price of $6,900.
