Most people know that a quality subwoofer can shake a whole room. But audio designer Roberto Dell Curti has built a subwoofer that does not shake just the room. Rather, the room is part of the horn subwoofer, and no doubt it can shake the whole house. Underneath his impressive home theater setup, the ground has been excavated and in its place, two horn channels 21 feet long running 3 feet deep give a home to the beast labeled the Real Total Horn. Each channel is powered by eight 18 inch woofers, giving a total of 16 woofers that are pumping thousands of watts of energy into the massive sound chambers.
Is it effective? Well, the biggest horn sub in the world can hit lows down to 10Hz, and create a virtual wave of sound energy while doing it. And if at some point we read that Italy has broken off from the mainland and floated away, I think we might know the reason why.
