This allows for powerful and dynamic audio playback suitable for water-based applications as well as powersport environments. With the dual 2-ohm voice coil, this Subwoofer can be flexibly installed in various configurations, depending on the specific requirements of your stereo system. The exact electromechanical properties, such as an impedance of 1 or 4 ohms for D2 and 2 or 8 ohms for D4, provide versatility in connection.

How do I best install the Prime RM112D2 in my vehicle?

For the installation of the Prime RM112D2 from Rockford Fosgate, it is crucial to note the correct cutout diameter of 276 mm. This Subwoofer fits in sealed, vented, or infinite baffle arrangements. The moisture and UV resistance of the material is ideal for marine environments. With a housing volume of 3.49 liters and a voice coil diameter of 2 inches, integration into your vehicle is seamless. Ensure proper wiring with the included ultra-flexible, insulated silicone cables to guarantee the longevity and optimal performance of your audio device.

Which vehicle models is the Prime RM112D2 compatible with?

The Rockford Fosgate Prime RM112D2 Subwoofer is compatible with a variety of vehicle models – however, the exact fit depends on the installation dimensions. The subwoofer has a size of 12", a cutout diameter of 276 mm, and a cabinet volume of 3.49 liters. This makes it ideal for standard DIN formats in many vehicles. An additional check of the specific dimensions in your vehicle is recommended to ensure the best possible installation and to fully benefit from the robust and powerful design of this subwoofer.

What frequency characteristics does the Prime RM112D2 Subwoofer offer?

The Prime RM112D2 Subwoofer features precise frequency characteristics that make it ideal for use in watercraft and powersport applications. With an Fs value of 28.5 Hz, it is particularly suited for deep bass. The Qts value is 0.59, allowing for balanced performance in a sealed or vented enclosure. The electromechanical parameters, such as Qes of 0.62 and Qms of 10.06, support efficient and harmonic vibrations, while the SPL value is set at 89 dB at 1W/1m, ensuring effective sound distribution.

What materials are used in the Prime RM112D2?

The Prime RM112D2 from Rockford Fosgate uses high-quality materials that are particularly useful for marine applications. The subwoofer features a UV- and salt fog-resistant Santoprene surround, providing long-lasting flexibility. Its cone body is made from injection-molded, mineral-filled polypropylene with UV inhibitors, ensuring additional stability under sunlight. The spring-loaded terminals are corrosion-resistant, and the ultra-flexible, fully insulated silicone wire supports resilience against environmental stressors, while the removable grilles maintain a uniform look.

How does the Xmax affect the sound of the Prime RM112D2 Subwoofer?

The Xmax of the Prime RM112D2 Subwoofer, which is specified at 7.0 mm, plays a crucial role in producing deep bass. Xmax refers to the maximum displacement of the diaphragm in one direction without producing significant distortion. A higher Xmax value improves bass reproduction capability, especially at high volumes, which guarantees excellent deep bass performance from this subwoofer. This feature ensures that the subwoofer can deliver bass accurately and without loss of sound quality, even under extreme environmental conditions.

Why is the Santopren edging an advantage?

The use of Santopren for the edging of the Prime RM112D2 offers numerous benefits. As a material, Santopren is known for its excellent UV and salt mist resistant properties, making it particularly suitable for marine environments. The flexibility and elasticity of the material contribute to overall stability, prevent tearing, and support long-term durability, even under demanding conditions. Its moisture resistance also plays a crucial role in ensuring that the Subwoofer delivers consistent performance over time, ideal for watercraft or powersport applications.

How do the impedance options behave with the RM112D2 Subwoofer?

The RM112D2 Subwoofer offers flexible impedance options with D2 models at 1 Ohm or 4 Ohm and D4 at 2 Ohm or 8 Ohm, making it versatile and adaptable for various applications and output stages. This variety of impedance allows you to use the Subwoofer in a range of amplifier combinations, ensuring optimal performance matching and distribution. Such options are essential for efficiently integrating the Subwoofer with existing audio systems that may require different voltage levels.

What role do the Thiele Small parameters play in the Prime RM112D2?

Thiele Small parameters, as specified in the Prime RM112D2, are important for acoustic optimization in specific enclosure types. The parameters Qes (0.62), Qms (10.06), and Qts (0.59) influence the electrical and mechanical efficiency of the Subwoofer. The value Fs (28.5 Hz) indicates the resonance frequency at which the diaphragm can freely oscillate, which is crucial for producing deeper bass frequencies. These parameters allow for precise enclosure matching for optimal sound quality and performance maximization in various environmental conditions, whether in sealed or ported enclosure models.
