The Prime RM112D2 subwoofer is characterized by precise frequency characteristics, making it ideal for use in watercraft and powersport applications. With an Fs value of 28.5 Hz, it is particularly suitable for deep bass. The Qts value is 0.59, which allows 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.
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 pressure 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.
The Xmax of the Prime RM112D2 subwoofer, which is specified as 7.0 mm, plays a crucial role in producing deep bass. Xmax stands for the maximum displacement of the diaphragm in one direction without generating significant distortion. A higher Xmax value improves bass reproduction capability, especially at high volumes, which guarantees excellent deep bass reproduction with this subwoofer. This feature ensures that the subwoofer is capable of delivering bass precisely and without loss of sound quality, even under extreme environmental conditions.
The use of Santopren for the edging of the Prime RM112D2 offers numerous advantages. 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 a long period, ideal for watercraft or powersport applications.
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 active output stages. This variety of impedances allows you to use the subwoofer in a wide range of amplifier combinations, ensuring optimal performance matching and distribution. Such options are crucial for efficiently integrating the subwoofer with existing audio systems that may require different voltage levels.
Thiele Small parameters, as specified in the Prime RM112D2, are important for acoustic optimization in specific types of enclosures. 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 vibrate freely, which is crucial for producing lower bass frequencies. These parameters allow for precise enclosure tuning for optimal sound quality and performance maximization in various environmental conditions, whether in sealed or open enclosure models.

Proprietary spring clips and corrosion protection technology

A standout feature of the Rockford Fosgate subwoofer is its spring-loaded compression terminals. These special connectors are corrosion-resistant and ensure a reliable connection over time. Unlike conventional terminals, these offer improved conductivity, resulting in a more direct and precise soundstage. A higher-quality connector might improve signal transfer in demanding environments, but Rockford Fosgate's integrated solutions already offer an optimal compromise between efficiency and durability.

UV and salt spray resistant Santoprene edging

The UV- and salt-fog-resistant Santoprene enclosure is a key feature for use in marine environments. This enclosure protects the subwoofer from the extreme outdoor conditions, including UV radiation and salt corrosion. Comparable products without this protection could be damaged more quickly, significantly shortening the lifespan of the contents. A more robust enclosure like this ensures stable sound quality over several years of use, even under the harshest conditions.

Mineral-filled polypropylene cone with UV inhibitors

The mineral-filled polypropylene cone gives the subwoofer exceptional rigidity and durability. UV inhibitors help protect the cone from sun damage and maintain consistent sonic performance. A cone of this quality minimizes distortion and delivers clean, crisp bass. Comparison with other commercially available materials shows that this cone type offers superior sonic stability and crack resistance.

Genuine marine-grade design guarantees durability

The Rockford Fosgate Prime RM112D2 features a true marine-grade design, ensuring maximum protection against moisture, mold, and external influences. This construction ensures the highest reliability in water environments. Subwoofers without this certification could easily fail or lose performance under extreme conditions. Rockford's marine-grade construction thus offers a high level of safety and functionality for its intended use.

Versatile installation options: Are other construction methods conceivable?

With the ability to be mounted in sealed, vented, or infinite baffle installations, the Prime RM112D2 opens up a wide range of installation possibilities. Each installation method has its own sonic characteristics: For example, vented enclosures offer deeper bass reproduction, while sealed enclosures deliver more precise sound. A subwoofer with limited installation options would offer less flexibility, but could be customized.

Cutout diameter and installation: 276 mm dimensional precision

The Rockford Fosgate RM112D2's 276 mm cutout diameter ensures the subwoofer can be precisely integrated into the intended mounting fixture. An ideal installation optimizes both the acoustic and mechanical performance of the subwoofer. Larger cutouts may require a more stable mounting, while smaller cutouts may restrict airflow and thus acoustic performance.

Aramid fiber braid resistant to moisture

The moisture-, tear-, and fatigue-resistant aramid fiber braid underscores the subwoofer's resistance to the elements. This fiber is known for its high strength and durability, ensuring the subwoofer performs flawlessly even under demanding conditions. Products without this fiber technology may experience faster performance degradation or damage when exposed to moisture and other external forces.

High SPL value: 89 dB for efficient sound pressure level

With a sound pressure level of 89 dB @ 1W/1m, the subwoofer demonstrates high efficiency in converting electrical energy into acoustic energy. This valuable performance indicator indicates that less amplifier power is needed to achieve a high volume level. While a higher SPL value would require an even lower power input, the current value already offers an appealing balance between efficiency and performance.

Xmax of 7.0 mm: Extended movement potential of the voice coil

The Rockford Fosgate Prime RM112D2 offers an Xmax of 7.0 mm, which corresponds to the maximum linear excursion of the voice coil. This value allows for deep, distortion-free bass output. A subwoofer with a higher Xmax would allow for greater voice coil movement and potentially deliver even deeper bass, but the given value is already optimal for the intended application.

Silicone lead wire: flexibility and insulation

The ultra-flexible, fully insulated silicone wire is a valuable feature that simplifies installation and reduces the risk of cable breakage. Compared to conventional wire materials, it offers better resistance to extreme temperatures and physical stress. Another advantage of this wire is its durability in demanding installation situations, which would be unattainable with a less flexible wire.

Thiele-Small Parameters: Technical Excellence of the RM112D2

The subwoofer has all the important Thiele-Small parameters, including a Qts of 0.59, Fs of 28.5 Hz, Vas, and Qes, which determine the electrical and mechanical quality. These parameters optimize bass reproduction and are crucial factors in cabinet design. A Qts value of 0.59 indicates balanced quality, suitable for precise bass reproduction in both sealed and vented enclosures.
