Portable speakers MBL 101 X-Treme
Of course, it is difficult to call a gadget a device weighing one and a half tons and costing 250 thousand dollars. On the other hand, in order to buy such acoustics, you have to be a real geek.
So, if you do not take into account the packaging cardboard, the weight of the home (!) Hi-End MBL 101 X-Treme Speaker System system will be approximately 1,500 kilograms. The set of speakers includes two audio towers (the speakers cannot be called speakers), a subwoofer and an amplifier. The materials used are carbon fiber, aluminum, steel and wood. Pulsating spheres are used as loudspeakers: one for low, one for medium and one for high frequencies.
The power is unknown, but, apparently, it is enough to hear knocking out speakers from the windowsill, knocking out a carpet on the street.
