Guys often like to brag about the size of their subwoofers… not sure why… but we do. Well this crazy Italian dude wins the bragging rights, hands down. He turned his entire basement into a massive subwoofer. The woofer is made of two cavities, each 3-feet deep and 31-feet long, these are driven by eight 18-inch woofers each.
