B² Audio Rampage 8 v3

The B² Audio Rampage 8 V3 is a powerful 20-cm subwoofer that combines high power handling and long cone excursion in a particularly compact design. With a power handling capacity of 1,000 watts RMS, this 8-inch subwoofer is suitable for both performance-oriented everyday systems and demanding SPL and demo setups.

The rigid carbon-fiber diaphragm ensures high mechanical stability and, together with the tall U-shaped foam surround, enables controlled diaphragm movement even at high volume levels. The Rampage 8 V3 is powered by a massive ferrite motor system weighing approximately 330 oz. The 2-inch voice coil is designed to handle high electrical loads.

Despite its compact 8-inch size, the Rampage 8 V3 delivers impressive low-frequency response and sound pressure levels. Depending on the desired tuning, it can be used in sealed, bass-reflex, or bandpass enclosures. To accommodate different amplifier configurations, the subwoofer is available in a D1 version with 2 × 1 ohm and a D2 version with 2 × 2 ohm.
