Frequently Asked Questions about Riot 12 V2

How big is the Subwoofer B2 Audio Riot 12 V2?

The B2 Audio Riot 12 V2 Subwoofer has a diameter of 12 inches or 30 cm. The outer diameter is 325 mm, the cutout diameter is 285 mm, and the mounting depth is 186 mm. These dimensions allow for flexible integration into various enclosure types, with particular attention to the mounting depth during enclosure construction. With its specific measurements, it is suitable for compact installations in vehicles where space-saving solutions are required without compromising sound quality. Considering the mentioned dimensions is crucial for optimal installation.

What performance specifications does the B2 Audio Riot 12 V2 offer?

The B2 Audio Riot 12 V2 has a power handling of 750 watts RMS and a dynamic peak power of 1500 watts, enabling powerful sound reproduction. With a resonance frequency of 29.9 Hz for the RIOT12D2 V2 and 30.4 Hz for the RIOT12D4 V2, it is excellent for low frequencies. The sensitivity is 87.4 dB and 84.9 dB, making it efficient. These performance characteristics ensure that the Subwoofer delivers optimal performance and durability even at high volume levels and intense use.

What type of enclosure is recommended for the Riot 12 V2?

The B2 Audio Riot 12 V2 is recommended for various types of enclosures. For a sealed enclosure, a volume of 22 to 25 liters with a QTC value of 0.65 to 0.7 is specified. For bass reflex enclosures, two options are described: 57 liters volume with 2x 4-inch aeroports and a length of 48 cm at a tuning frequency of 38 Hz, or 80 liters volume with the same openings and a tuning frequency of 32 Hz. These recommendations promote maximum performance output and efficiency of the Subwoofer under different sound requirements.

What about the cooling of the B2 Audio Riot 12 V2?

The B2 Audio Riot 12 V2 features improved cooling, thanks to a ventilated pole with XD Flow technology and efficiently ventilated voice coils. The development focused on optimizing heat dissipation to increase performance under heavy load by 25% compared to previous models. These cooling mechanisms ensure that the voice coils maintain a constant temperature, which both enhances the longevity of the Subwoofer and prevents performance reduction or damage during intense use.

What are the key electromechanical parameters of the Riot 12 V2?

The electromechanical parameters of the Riot 12 V2 are crucial for its audio-acoustic properties. With a resonance frequency (FS) of 29.9 Hz and 30.4 Hz, and parameters like CMS of 90 μm/N and MMS of 300.8 g and 287.3 g, it shows impressive control in the deep bass range. The BL value of 19.29 and 22.8 reflects the electromagnetic motor force that ensures precise diaphragm movements. These parameters combine to guarantee outstanding sound reproduction, ideal for operation in precisely tuned speaker systems.

What information is available about the voice coil of the Riot 12 V2?

The B2 Audio Riot 12 V2 Subwoofer is equipped with a 3-inch voice coil designed for improved load capacity and heat dissipation. The voice coil is made from high-quality materials that ensure efficient energy transfer and thermal management, thus minimizing the risk of overheating under high power. Vented Nomex former supports the voice coil by providing stability and contributing to sound quality. The robust construction of the voice coil is crucial for the overall performance of the Subwoofer, making it resilient against intense usage conditions.

How is the B2 Audio Riot 12 V2 properly installed?

When installing the B2 Audio Riot 12 V2 Subwoofer, it is essential to consider the specific dimensions. With an outer diameter of 325 mm and a cutout diameter of 285 mm, the mounting location should be carefully selected to ensure a solid placement. The mounting depth of 186 mm requires sufficient space behind the Subwoofer. Be sure to choose the appropriate enclosure volume according to the recommendations to achieve optimal sound performance. Foam gaskets or similar materials can help minimize unwanted vibrations.

What technical features distinguish the Riot 12 V2?

Notable technical features of the Riot 12 V2 include the large 3-inch voice coil, the ventilated Nomex centering spiders, and the engraved backplates that ensure exceptional sound quality. The innovative vented pole with XD Flow improves the cooling of the voice coils and promotes a 25% power increase compared to previous models. Together, this variety of features allows for an impressive frequency response of 10 Hz to 500 Hz and a nominal impedance available as Dual 2 Ohm or Dual 4 Ohm, ideal for installation variability.

What are the recommended installation methods for the Riot 12 V2?

For the B2 Audio Riot 12 V2, installation in a well-tuned enclosure is recommended. For sealed enclosures, a volume of 22-25 liters is ideal, while for bass reflex enclosures, 57 liters with a tuning frequency of 38 Hz or 80 liters with a tuning frequency of 32 Hz are optimal. The precise placement of the Aeroports and consideration of the enclosure dimensions are central aspects to achieve maximum bass output and sound quality. Correct distance measurement and the use of sealing material help reduce vibrations and optimize sound performance.

Which vehicle models is the Riot 12 V2 compatible with?

The B2 Audio Riot 12 V2 Subwoofer is compatible with a variety of vehicle models due to its universal dimensions, provided the existing installation space meets the required measurements. The outer diameter of 325 mm and the installation depth of 186 mm must match the available space in the vehicle to ensure optimal installation. For custom installation purposes, it is advisable to check the specific dimensions of the intended installation location in the car and make adjustments to the subwoofer enclosure if necessary to achieve seamless integration.

Es lohnt sich!

Ich habe sie an den Sounddigital 800.4 Evo6 angeschlossen. Und ich bin mehr als zufrieden. Mitteltöner laut und auch präzise. Hochtöner brennen nicht in den Ohren, die sind laut und geben das, was sie sollen. Gut angelegtes Geld.

Laut ... einfach nur laut

Also ich sag es mal so... wenn man ein Lautes Kompo System sucht, mit noch sehr guten Klangeigenschaften.
Naja der sollte das T3 von Rockford nehmen.
Ich hatte viele Systeme verbaut und bin dann wieder zurück zum T3 und habe nun 3 verbaut... schön laut und sehr feiner Klang.
