Frequently Asked Questions About the B² Audio Riot 12 Subwoofer

How much power does the B² Audio Riot 12 require for optimal performance?

The Riot 12 is rated for 1,000 watts RMS and should ideally be powered by a power amplifier rated between 800 and 1,200 watts RMS. In the dual 4-ohm configuration, it achieves its best performance with a stable 2-ohm or 8-ohm load, depending on the wiring.

What enclosure size does B² Audio recommend for the Riot Series subwoofer?

For sealed enclosures, 28–35 liters is recommended, while bass-reflex enclosures should ideally have a volume of 55–65 liters. The exact dimensions depend on the desired tuning and the available installation space.

How does the second generation differ from the first Riot Series?

The V3 generation features improved voice coil cooling, optimized surround geometry, and reinforced centering spiders. These upgrades enable higher power handling and more precise bass reproduction while reducing distortion.

Can the subwoofer be used even at lower frequencies below 30 Hz?

Yes, the Riot 12 easily reaches frequencies down to 25 Hz with good efficiency. Its special suspension allows for large excursions even at very low frequencies, making it ideal for music and SPL applications.

How long is the warranty, and what does it cover?

B² Audio offers a two-year manufacturer's warranty on the Riot 12 when used properly. This warranty covers defects in materials and workmanship but excludes damage caused by overloading or improper installation.

Is the Riot 12 suitable for everyday use or only for competitions?

Despite its competition-grade specifications, the subwoofer is ideal for everyday use. Its robust construction and efficient cooling ensure durability even with regular use at moderate power levels.

What accessories are needed for installation?

In addition to the subwoofer itself, you'll need speaker cables with a cross-sectional area of at least 10 mm², a suitable enclosure, and mounting screws. For best results, we also recommend using sound-deadening material for the enclosure.
