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.
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.
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.

Rampage RC2

Ich brauche da glaube nicht so viel erzählen.
Es ist ein echter kleiner Subwoofer und der läuft ganz gut.
Angeschlossen an eine kleine Endstufe mit Subwoofer Steuerung FREQ und LEVEL und dann kann man das ganze gut einpegeln.
