There's a guy over at Audioholics (Warpdrive) who made his own dual 18" subwoofers (he has three he made so a total of six 18 drivers. Here's the subwoofer I dream of. :handgestures-thumbup:
The power to drive those 6 18" drivers.
and a pic of his wife (who helped him build these for perspective as to how large these subs are.
I thought I was bad about subs, look at how close he sits to two of his three in the room monster subs. Holy Shit!!!!!
The inside with four king size pillows in each sub.
