Frequently Asked Questions about Rampage RC2

What are the specific performance specifications of the Rampage RC2 Subwoofer?

The Rampage RC2 from B2 Audio is a 2-inch Subwoofer, specifically designed for RC cars. It offers an RMS power of 10 watts and an impedance of 4 ohms. The voice coil size is 0.8 inches, providing a compact sound solution in RC models. The Subwoofer has a sensitivity of 72.9 dB at 1 watt, supporting precise sound reproduction. With a maximum linear excursion of 4 mm, the RC2 is capable of effectively handling low frequencies. These performance specifications make it ideal for use in small model vehicles, where space and efficiency are crucial.

What materials are used in the construction of the Rampage RC2?

The Rampage RC2 from B2 Audio uses high-quality materials to ensure long-lasting and robust performance. The frame is made of cast aluminum, which not only provides a stable installation but also offers excellent heat dissipation. The paper cone is pressed and equipped with a foam surround to enable authentic sound emulation and reliable response. This combination of materials contributes to the acoustic efficiency of the Subwoofer while ensuring it withstands the harsh use in RC vehicles without any issues.

How is the B2 Audio basket design of the Rampage RC2 structured?

The B2 Audio basket design of the Rampage RC2 from B2 Audio replicates a miniature version of full-size Subwoofers. This structure aims to provide the acoustic advantages of larger Subwoofers in a compact format for RC cars. The cast aluminum body offers a solid base for the diaphragm, while the arrangement of components is optimally distributed to allow for the best possible resonance and sound fidelity. This is particularly helpful in compact modes, where space is limited, but no compromises on sound quality can be made.

What are the technical specifications of the Rampage RC2 regarding frequency response and resonance frequency?

The Rampage RC2 from B2 Audio offers a resonance frequency (FS) of 94.5 Hz, enabling it to reproduce deep tones within a precise frequency range. This specification is crucial for use in RC cars, as the right resonance frequency allows for clear and full bass that enhances the miniature vehicle. The RC2 also has the following Q values: QMS is 4.79, QES is 1.45, and QTS is 1.11. These values indicate how the system responds to mechanical and electrical resonances. Together with a BL value of 2.6, the RC2 provides a balanced combination of mechanical and electromagnetic control.

How does the Rampage RC2 Subwoofer fit into 1:10 scale RC models?

The Rampage RC2 from B2 Audio is specifically designed for compatibility with 1:10 scale RC models. With a cutout diameter of 1.95 inches and a mounting depth of 2.32 inches, the Subwoofer allows for seamless integration into these vehicles without compromising performance. The overall diameter of 2.24 inches and the compact frame ensure that it fits easily into the limited space of these model designs. Thanks to its optimized size and efficient construction, the Rampage RC2 can be effectively integrated into standard model car chassis.

What parameters define the sound quality of the Rampage RC2?

The sound quality of the Rampage RC2 is defined by various technical parameters. The pressed paper cone paired with a foam surround allows for precise and authentic sound emulation. The SD value of 15.2 cm² indicates the effective diaphragm area responsible for sound pressure generation. With an MMS value of 4.46 g, the effective moving mass of the system is denoted, which influences the agility and responsiveness of the Subwoofer. This combination ensures that the Rampage RC2 not only impresses with loud bass but also accurately reproduces finer sound details.

Can the Rampage RC2 Subwoofer be used in conventional RC battery drive systems?

Yes, the Rampage RC2 Subwoofer from B2 Audio can be easily used in conventional RC battery drive systems. With a power of 10 watts RMS and an impedance of 4 ohms, the Subwoofer is compatible with most battery-powered RC systems, allowing for flexible integration into existing RC models. The low power consumption ensures that battery load remains minimal without compromising sound performance. This is particularly advantageous for users who want to enhance the sound of their RC cars without significantly shortening battery life.

How do I optimally install the Rampage RC2 in my RC car?

To optimally install the Rampage RC2 in your RC car, follow the specified installation parameters: The cutout diameter is 1.95 inches and the installation depth is 2.32 inches. Ensure that the RC chassis has enough space. Use the die-cast aluminum frame and the mounting flange to achieve a stable and vibration-free position. Proper placement in the RC car leads to improved sound performance by minimizing unwanted resonances. Avoid direct loads on the paper cone to maximize durability. Check all electrical connections for correct contact and polarity to avoid malfunctions.

What impact does the QTS value of the Rampage RC2 have on its performance?

The QTS value of the Rampage RC2 is 1.11, an important parameter for assessing the overall quality of the Subwoofer in terms of mechanical to electrical Damping ratio. A QTS above 0.5 indicates a rather overdamped response, meaning that the Subwoofer sounds more controlled and less boomy. Thus, the RC2 offers a stable sound image with clear bass in a compact housing. Especially in an RC car, where the overall damping of the vehicle system is limited, such a QTS value contributes to a smooth and powerful bass reproduction.

What influence does the BL value have on the Rampage RC2?

The BL value of the Rampage RC2 Subwoofer is 2.6, this value represents the magnetic force acting on the voice coil, which is essential for the efficiency and control of the diaphragm movement. A higher BL value indicates stronger control and less distortion, leading to higher sound accuracy. With a BL of 2.6, the Rampage RC2 delivers powerful and precise bass, which is particularly important in the confined environment of an RC car to achieve clear audio reproduction. The interaction between the diaphragm and magnetic force is thus optimized.

vibe powerbox65.4m v7 samen met quadlock connector besteld.

Levertijd prima in orde.

vibe powerbox65.4m v7 in mijn vrachtwagen Volvo Fmx 2024 gemonteerd met Quadlock.
Alleen plug and play super fantastisch systeem. Alles standaard op 12v geen omvormer of iets nodig.
In bouw tijd ongeveer 30 minuten.
Radio verwijderen connectors verbinden vibe powerbox65.4m v7 aansluiten.
Alle originele radio instellingen op nul of uit gezet. Volume op 3/4 langzaam de powerbox65.4m v7 open draaien en al het werk laten doen.
Perfect kristal helder geluid in combinatie met mijn Rockford t142 en Rockford p1650 speakers. De bass geluid is verbeterd maar voor echte diepe baas waar ik persoonlijk niet zo van ben heb je echt een externe subwoofer nodig.
Kortom een goede upgrade van je radiogeluid is gegarandeerd.

Masori was goed met de prijs, perfecte communicate met hun gehad. Een echte aanrader.

Used as replacement to Škodas canton system

Used as replacement to Škodas canton system subwoofer.
Works great, fits right into the factory box, need to remove only one little pin and use new skrews.
Sound is even better then it was before.
Plug and play for that system.

Richtig guter Tiefmitteltöner mit Alu-Gusskorb

Richtig guter Tiefmitteltöner mit Alu-Gusskorb und um 30Hz niedrigerer Resonanzfrequenz als üblich im 10cm-Woofer-Bereich. Dadurch kann sich dieser 10cm-Woofer auch wirklich Tiefmitteltöner nennen.

Real power

Ziet er goed uit,Heb 2 accu`s aangesloten, Daar tussen Stinger scheidingsrelais van 200 amp,
Ook moet je 2x zekering van 200 amp plaatsen,

Heb bewust voor Stinger 200 ampere gekozen omdat ik een standaard dynamo heb is dat voldoende.
