Some people do really weird things in their basements, including this crazy Italian man who converted his entire basement into one giant horn subwoofer back in the year 2000.

The subwoofer, which consists of two 3-feet deep and 31-feet long cavities, releases more than 110dB. Boy would I hate to be his neighbor—maybe that’s why Coachella is in the middle of nowhere. Our guess is his insides have disintegrated by now.
