Frequent questions about Rampage RC2

Was sind die spezifischen Leistungsdaten des Rampage RC2 Subwoofers?

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.

Welche Materialien werden beim Bau des Rampage RC2 verwendet?

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 that it can easily withstand the harsh use in RC vehicles.

Wie ist das B2-Audio-Korbdesign des Rampage RC2 strukturiert?

The B2 Audio basket design of the Rampage RC2 by 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 die-cast aluminum body offers a solid base for the diaphragm, while the arrangement of the components is optimally distributed to enable the best possible resonance and sound fidelity. This is particularly helpful in compact modes, where space is limited, but no compromises can be made on sound quality.

Welche technischen Spezifikationen hat der Rampage RC2 hinsichtlich Frequenzgang und Resonanzfrequenz?

The Rampage RC2 from B2 Audio offers a resonance frequency (FS) of 94.5 Hz, which enables it to reproduce deep tones in a precise frequency range. This specification is crucial for use in RC cars, as the correct 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. Along with a BL value of 2.6, the RC2 provides a balanced combination of mechanical and electromagnetic control.

Wie passt der Rampage RC2 Subwoofer in RC Modelle im Maßstab 1:10?

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 on 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. With its optimized size and efficient construction, the Rampage RC2 can be effectively integrated into the common model car chassis.

Welche Parameter definieren die Klangqualität des 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 referred to, which influences the mobility 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.

Kann der Rampage RC2 Subwoofer in herkömmlichen RC Batterieantriebssystemen verwendet werden?

Yes, the Rampage RC2 subwoofer from B2 Audio can be easily used in conventional RC battery-powered systems. With a power of 10 W RMS and an impedance of 4 Ohms, the subwoofer is compatible with most battery-operated RC systems, allowing for flexible integration into existing RC models. The low power consumption ensures that the 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 reducing battery life.

Wie installiere ich den Rampage RC2 in mein RC Auto optimal?

To optimally install the Rampage RC2 in your RC car, observe 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. The correct 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 proper contact and polarity to avoid malfunctions.

Welche Auswirkungen hat der QTS-Wert des Rampage RC2 auf seine Leistung?

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. 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 enclosure. 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.

Welchen Einfluss hat der BL-Wert auf den 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 greater 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 playback. The interaction between the diaphragm and magnetic force is thus optimized.

Super guter Subwoofer

Super Subwoofer mit extrem tiefem Bass. Die Kabel sind dick und hochwertig verarbeitet. Es gibt nichts zu beanstanden. Absolut empfehlenswert.

Alpine tube 12 bazooka , Un sacré caisson de basses ,

Un sacré caisson de basses , j'ai eu un 46 cm killer 454 de l'époque année 90 , qui tapait vraiment bien , mais ce tube est bien plus fort et plus ample, toutes les basses passent sans problème, avec une télécommande à réglage multiples taramps eq bass , et un ampli Machete de masori , le couple est parfait, personnellement j'en ai deux tubes et ça donne énormément, avec l'ampli 2 x 530 en 4 ohms . Parfois le plus simple est bien meilleur et plus durable .

X-10 v3 d2

Hallo. Sehr freundlicher Kundenservice und schnelle Auftragsabwicklung. Der Lautsprecher ist brandneu und unbenutzt. Ich habe ihn vor einiger Zeit gekauft, aber erst kürzlich das Gehäuse fertiggestellt. Die Parameter entsprechen den Herstellerangaben: 42,5 Liter Nettovolumen, abgestimmt auf 32 Hz und 21 mm starkes Sperrholz. Ich hatte noch nie einen 10-Zoll-Lautsprecher und wusste nicht, was mich erwartet, aber das Ergebnis hat meine kühnsten Erwartungen übertroffen. Der Bass aus einem so kleinen Lautsprecher in einem so kleinen Gehäuse ist einfach unglaublich. Um den X-10 zu kaufen, habe ich meinen DD 712f in einem 70-Liter-Gehäuse verkauft, und der war ein Volltreffer. Der Sundown ist in jeder Hinsicht besser. Ich kann diesen Lautsprecher und den Händler, bei dem ich ihn gekauft habe, wärmstens empfehlen. Beste Grüße.
