World’s largest horn subwoofer rocks the house to its foundations and beyond | DVICE
When audio designer Roberto Delle Curti wanted the world’s biggest, baddest subwoofer, he didn’t go prancing off to some snooty audio store. He got out a shovel. Underneath his world-class home theater lurks the Real Total Horn, consisting of two cavities that are three feet deep and 31 feet long. These tunnels function as horns, each driven by eight 18-inch woofers for a total of 16 woofers — along with thousands of watts of raw power.
