Soundstream acoustical engineers along with DB Drag guru, Ronal Murphy developed the XXX-15 sub woofer to handle 8.5 kilowatts of power. This full-throttle innovation puts them in a class by themselves. Our engineers use very high temperature glues along with a 4”, flat wound, copper
clad aluminum voice coil to keep them from critical mass melt down.
If you’re looking for sonic terror, you need to stack the deck with XXX.
