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 needed 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 on sound quality. Considering the mentioned dimensions is crucial for optimal installation.
The B2 Audio Riot 12 V2 has a power handling capacity of 750 watts RMS and a dynamic peak power handling of 1500 watts, allowing for 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 excellently suited 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 with intensive use.
The B2 Audio Riot 12 V2 is recommended for various enclosure types. 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 the maximum performance output and efficiency of the subwoofer under different sound requirements.
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 increases the longevity of the subwoofer and prevents performance reduction or damage during intense use.
The electromechanical parameters of the Riot 12 V2 are crucial for its audio-acoustic properties.

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 installation depth of 186 mm requires sufficient space behind the subwoofer. Make sure to choose the appropriate enclosure volume according to the recommendations to achieve optimal sound performance. Foam seals or similar materials can help minimize unwanted vibrations.
The remarkable 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 ventilated pole with XD Flow improves the cooling of the voice coils and promotes a performance increase of 25% compared to previous models. Together, this variety of equipment enables 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 variability in installation.
For the B2 Audio Riot 12 V2, installation in a well-tuned enclosure is recommended. For closed 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 exact 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.
The B2 Audio Riot 12 V2 subwoofer is compatible with a variety of vehicle models due to its universal dimensions, provided that 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, if necessary, make adjustments to the subwoofer enclosure to achieve a seamless integration.

Fein!

Der Riot kam bei mir als Nachfolger vom Rage 8" und ist mehr als würdig. Ich bin absolut zufrieden und habe nun vermutlich mehr Leistung, als ich je brauche. 😉 Die Qualität des Woofers ist großartig, perfekt verpackt. Schnelle Lieferung. Es stimmt alles.

12 (30cm) Subwoofer Riot 12 V2 from B2 Audio: Technological excellence

The B2 Audio Riot 12 V2 impresses with its successful combination of performance and efficiency, reflected in its generous 12-inch design. In the highly competitive car hi-fi world, this subwoofer offers a perfect balance between fidelity and sound pressure. The products in the Riot series are known for their outstanding value, with B2 Audio offering uncompromising quality at attractive prices.

Ultimate power handling: 750 watts RMS for unparalleled performance

With a stable power handling of 750 watts RMS, the B2 Audio Riot 12 V2 impresses with its high continuous power, allowing a peak power handling of 1500 watts in the most dynamic tones. These characteristics provide a robust foundation for ensuring stable performance in intensive bass applications. While a higher RMS rating would theoretically result in even more volume, at 750 watts, the subwoofer is already at the upper end of the spectrum, ensuring a wide range of applications and stable performance.

Dual-ohm configuration: Flexibility through 2 ohm and 4 ohm options

The Riot 12 V2 offers remarkable flexibility with its dual 2-ohm and dual 4-ohm configurations. This allows you to choose the right impedance for your specific system. In a dual 2-ohm configuration, the DC resistance (Re) is 1.9 ohms, while in the 4-ohm version it measures 3.2 ohms. Lower impedance offers the potential for higher sound pressure levels, while higher values ​​are better suited for systems that prioritize stability and lower power losses.

Precise frequency response: spectrum from 10 Hz to 500 Hz

The frequency response from 10 Hz to 500 Hz demonstrates that the Riot 12 V2 is capable of effortlessly reproducing the lowest tones as well as mid-bass frequencies. This bandwidth makes it ideal for bass-rich music styles, as it reproduces the low frequencies with detail and precision. Extending the frequency range in any direction could result in a loss of both the detail and brilliance of the bass, but these specifications are excellently optimized for this.

Improved sensitivity: 84.9 dB and 87.4 dB for exceptional resonance

The sensitivity values ​​of the Riot 12 V2 are 87.4 dB for the 2-ohm version and 84.9 dB for the 4-ohm version. This specification indicates how efficiently the subwoofer can generate sound pressure from a given electrical power. While higher dB values ​​mobilize more intense sound pressure, the available range of this model also ensures dynamically exciting audio reproduction.

Xmax advantage: 36 mm for precise diaphragm excursion

With an Xmax value of 36 mm, the Riot 12 V2 delivers remarkable cone excursion. The Xmax indicates the amount of linear movement the subwoofer can generate before distortion occurs. While a higher Xmax could theoretically produce an even more intense bass experience, the current design offers enough headroom to deliver pure bass pleasure without compromising the sound.

Resonance frequency of 29.9 Hz and 30.4 Hz: Strategic precision

The resonant frequencies of 29.9 Hz for the dual 2-ohm version and 30.4 Hz for the dual 4-ohm version optimize low-frequency sounds, allowing the subwoofer to mesmerizingly bring out deep, pounding bass rhythms. This represents a good compromise between bass richness and dynamic sound structure. A higher Fs value would shift the focus away from the lowest notes, while a lower one could potentially impair definition at such levels.

Flexible cabinet volume: Adaptable to closed and bass reflex systems

With recommended volumes of 22-25 liters for sealed cabinets and 57-80 liters with the appropriate port length for bass reflex systems, the Riot 12 V2 demonstrates its adaptability. These values ​​favor various application scenarios, ranging from sonically rich to impressively powerful designs. Smaller cabinets optimize the transient response, while larger volumes are more optimized for bass efficiency. These and other technical details demonstrate the potential of the Riot 12 V2 at masori.de. You can install it on-site in Frankfurt (Oder), or take advantage of the comprehensive assistance provided by our expert support FAQ & Help for your optimized audio installation.
