The World's Biggest Subwoofer

[Big Daddy]

Royal Device, an Italian audio manufacturer, created the record breaking subwoofer. Two horns made
of bricks and mortar (yes, you read it correctly) are hidden beneath the floor of a 23ft by 29ft
home theater room. Each horn measures 9.5 meters (~31.2 ft) long by 1 meter (3.28 ft) deep with a
2.2 meter (7.2 ft) mouth, and is driven by eight 18.5 inch drivers. Twenty four additional
full-range drivers serve the other channels. The system can reproduce frequencies down to 10 Hertz.
The designer, Roberto Delle Curti, owns the subwoofer. You can see more pictures at

I don’t want to hear about Elemental Designs and other sub par subwoofers.
Driver King, you can close your ED thread. I am moving to Italy.
