The B2 Audio RAMPAGE 8 V3 is an 8-inch subwoofer rated at 1000W RMS and 2000W max. It has dual 1-ohm voice coils, each 2 inches (50.4 mm) in diameter and wound with copper. The coils allow flexible wiring options.
The cone is carbon fiber and sits in a tall U-shaped foam surround, which gives it a 17 mm one-way Xmax. A ferrite motor weighing 330 oz drives it. Connections are made through 8 gauge push terminals.
It can be used in sealed, ported or 4th-order bandpass enclosures. Recommended enclosure specs are listed below.
