Frequent questions about Prime R2D2-10/R2D4-10


Was sind die RMS- und Maximalbelastbarkeiten des Rockford Fosgate Prime R2D2-10 Subwoofers?

The Rockford Fosgate Prime R2D2-10 offers an RMS power handling of 250 watts, allowing it to continuously handle high power over extended periods. The maximum power handling is 500 watts, enabling it to deliver powerful bass even in demanding car audio setups. These power parameters ensure that the subwoofer provides clear and distortion-free sound even under intense use. The dual voice coil configuration allows for flexible use of the available power by utilizing different impedance combinations to extract the best possible performance from the amplifier.

Wie flexibel ist die Dual Voice Coil Konfiguration des Rockford Fosgate Prime R2D2-10 für unterschiedliche Installationen?

The Dual Voice Coil (DVC) configuration of the Rockford Fosgate Prime R2D2-10 allows for enormous installation flexibility, as there are two separate terminals available on each side. This enables you to connect the subwoofer in series or parallel to achieve the desired impedance, which is particularly useful when using different amplifier options in your car audio system. This flexibility not only makes it easier to adapt to different electrical systems but also optimizes the overall performance and efficiency of the subwoofer, regardless of whether it is installed in a sealed or vented enclosure.

Welche Eigenschaften bietet der Mica-injizierte Polypropylen-Konus des Prime R2D2-10 Subwoofers?

The mica-injected polypropylene cone of the Rockford Fosgate Prime R2D2-10 is characterized by its high stiffness and low deformation at high speeds, ensuring precise and distortion-free bass reproduction. The use of mica as a reinforcement material in polypropylene provides improved heat dissipation and durability, especially under high power loads. This material combination also supports a faster and more accurate return of the diaphragm to its original position, which is crucial for the accuracy and clarity of bass reproduction. Especially in demanding audio setups, the special cone ensures a balanced sound image with deep, clear bass.

Wie funktioniert die integrierte Spiderentlüftung im StampCast-Korb des Rockford Fosgate Prime R2D2-10?

The integrated spider ventilation in the StampCast basket of the Rockford Fosgate Prime R2D2-10 serves to efficiently cool the subwoofer motor. This special design optimizes the airflow around the spider, improving heat dissipation and preventing the motor from overheating. This is particularly important at high power outputs, as a constant temperature ensures the performance and longevity of the subwoofer. Thus, the spider ventilation helps ensure that the Rockford Fosgate Prime R2D2-10 operates stably and reliably even under intense use by minimizing the thermal load on the motor.

Welche Gehäuseoptionen sind für den Rockford Fosgate Prime R2D2-10 Subwoofer geeignet?

The Rockford Fosgate Prime R2D2-10 is optimized for both sealed and vented enclosures. A sealed enclosure with a volume of 16.7 liters provides precise and powerful bass reproduction, ideal for compact installations and quick responses. Alternatively, the vented enclosure with a volume of 39.6 liters allows for extended bass reinforcement and deeper frequencies, which is particularly interesting for larger vehicles and enthusiastic bass lovers. The ability to choose between these enclosure types gives you the flexibility to adjust the sound characteristics according to your personal preferences and the acoustic properties of your vehicle.

Welche technischen Parameter weist der Rockford Fosgate Prime R2D2-10 in Bezug auf Frequenz und Impedanz auf?

The Rockford Fosgate Prime R2D2-10 subwoofer has a resonance frequency (Fs) of 34.6 Hz, allowing it to reproduce deep bass frequencies accurately. The nominal impedance is 3.84 ohms, which, combined with the dual voice coils, provides flexible connection options to match the overall impedance to the amplifier system. Other important parameters include Qts of 0.47, indicating that the subwoofer is suitable for both sealed and vented enclosures. The Thiele-Small parameters such as Vas of 39 liters and Sd of 339.8 cm² support integration into various enclosure configurations and ensure that the Rockford Fosgate Prime R2D2-10 delivers optimal performance in a wide range of car audio setups.

Wie unterstützt die anodisierte Aluminium-Schwingspule des Prime R2D2-10 eine verbesserte Audioqualität?

The anodized aluminum voice coil of the Rockford Fosgate Prime R2D2-10 significantly contributes to improved audio quality, as the anodized aluminum offers higher thermal conductivity and enhanced strength. This allows for efficient heat dissipation during intense use, resulting in more stable performance and lower distortion. Additionally, the anodized surface ensures a longer lifespan for the voice coil, as it is better protected against oxidation and other environmental influences. Combined with the linear spider and the 16 AWG tinsel leads, the high-quality voice coil ensures that the subwoofer delivers precise and dynamic bass reproduction, even at high volumes.

Was sind die empfohlenen Anschlussarten für den Rockford Fosgate Prime R2D2-10 Subwoofer?

The Rockford Fosgate Prime R2D2-10 subwoofer uses 4mm² compression terminals with a diameter of 51 mm, ensuring a secure and stable connection. These terminals are ideal for use in car audio systems, where reliable electrical connections are crucial. The dual voice coil configuration allows for the use of dual 2-ohm speaker connections, providing multiple connection options depending on the specific requirements of your amplifier and system architecture. It is recommended to use high-quality cables and appropriate terminal connectors to ensure optimal signal transmission and minimal power loss, maximizing the overall performance and sound quality of the subwoofer.

Welche Platzierungs- und Installationstipps gibt es für den Rockford Fosgate Prime R2D2-10 hinsichtlich Abmessungen und Einbautiefe?

When installing the Rockford Fosgate Prime R2D2-10 subwoofer, it is crucial to consider the installation depth of 109 mm to ensure that the subwoofer fits into the intended enclosure and the available space in the vehicle. With a cutout diameter of 232 mm, the subwoofer requires sufficient space for the free movement of the diaphragm to ensure optimal bass reproduction. It is advisable to design the enclosure volume according to the recommendations – 16.7 liters for a sealed enclosure or 39.6 liters for a vented enclosure – to fully utilize the performance and efficiency of the Rockford Fosgate Prime R2D2-10. Make sure that the subwoofer is securely mounted and that there is enough space for air circulation around the StampCast basket to maintain a constant operating temperature.

Welche technischen Vorteile bietet die Xmax des Rockford Fosgate Prime R2D2-10 für die Basswiedergabe?

The Xmax of the Rockford Fosgate Prime R2D2-10 is 6.5 mm, which defines the maximum linear excursion range of the diaphragm. A higher Xmax allows the subwoofer to produce greater sound pressure levels (SPL) without reaching saturation, resulting in clearer and more dynamic bass reproduction. This is particularly beneficial for car audio enthusiasts who appreciate powerful and precise bass even at higher volumes. The combination of a robust StampCast basket, the integrated spider venting, and the high Xmax ensures that the Rockford Fosgate Prime R2D2-10 delivers excellent performance in both sealed and vented enclosures, maximizing the depth and clarity of the bass frequencies.
