These power specifications, combined with a high sensitivity of 89 dB (SPL @ 1w/1m), ensure that the subwoofer delivers impressive bass reproduction even in demanding environments. The sub is equipped with a voice coil diameter of 2 inches, which provides efficient and powerful bass. The dual 2-ohm nominal impedance allows for flexible adaptation to various amplifier configurations.

Welche Materialien und Bauweise werden beim Prime RM112D2B verwendet?

The Prime RM112D2B relies on high-quality materials such as an injection-molded polypropylene cone body, which is equipped with UV inhibitors. These ensure durability and resistance to environmental influences, which is particularly advantageous in marine environments. The mineral-filled material stabilizes the cone and improves sound fidelity. Moisture resistance is ensured by an aramid fiber mesh that prevents cracks and fatigue. To avoid corrosion, spring-loaded pressure clamps are used, which ensure an optimal and lasting connection.

Wie widerstandsfähig ist der RM112D2B gegenüber Umwelteinflüssen?

The RM112D2B has been specifically designed for use in watercraft and powersport applications, offering a complete UV and salt mist resistant construction. The Santoprene edging and ASA injection molded parts ensure high resistance to UV radiation and moisture. The materials have been selected to withstand even extreme conditions and provide a long service life. This makes the subwoofer particularly suitable for applications in marine environments, where reliability and weather resistance are crucial.

Welche Installationsoptionen bietet der Prime RM112D2B?

The Prime RM112D2B subwoofer can be installed in various enclosure types, including sealed, vented, or infinite baffle designs. This versatility allows the subwoofer to be adapted to specific acoustic requirements and spatial conditions. The cutout diameter is 276 mm, which enables easy installation in most common speaker enclosures. The volume of the woofer is 3.49 liters, providing ample space for rich and deep bass. When installing, it is important to ensure that the sub is adequately ventilated to guarantee optimal performance.

Welche technischen Merkmale sind beim RM112D2B besonders hervorzuheben?

The RM112D2B has some outstanding technical features: The proprietary spring-loaded pressure terminals provide a corrosion-resistant connection. With a maximum linear displacement (Xmax) of 7.0 mm, the subwoofer delivers precise bass reproduction at high levels. The subwoofer is CEA-2031 compliant, thus certified for true power comparison. The impedance options of 1 or 4 Ohms (D2) and 2 or 8 Ohms (D4) allow for versatile connection possibilities to various amplifier systems to ensure optimal adaptation to sound preferences.

Welche Thiele-Small-Parameter besitzt der Prime RM112D2B?

The Prime RM112D2B has the following Thiele-Small parameters: The effective diaphragm area (Sd) is 585 cm², and the voice coil inductance (Le) is specified at 2.16 mH. The DC resistance (Re) is 3.7 Ohms. The quality factors Qes and Qms are 0.62 and 10.06, respectively, resulting in a total quality factor (Qts) of 0.59. The resonance frequency (Fs) is set at 28.5 Hz, which is predestined for deep bass reproduction. Such differentiated parameters are essential for precise technical adjustment and sound transmission in different enclosure configurations.

Wie verhält sich der RM112D2B in Bezug auf die Impedanz bei unterschiedlichen Modellen?

The Prime RM112D2B offers flexible impedance options. You can operate the D2 version at either 1 ohm or 4 ohms, while the D4 version provides 2 or 8 ohms. This adaptability allows the subwoofer to be tailored to a variety of amplifier systems and setup requirements. Especially in high-power audio setups in the marine sector, this can be crucial for effective system configuration to achieve maximum sound enjoyment without compromising speaker control and safety.

Welche Abmessungen hat der RM112D2B und wie beeinflussen diese die Einbauoptionen?

With a size of 12 inches and a cutout diameter of 276 mm, the Prime RM112D2B is designed for a variety of installation options. These dimensions allow the subwoofer to be integrated into many common speaker boxes or specially adapted enclosures. Additionally, this facilitates fitting into tight spaces, as often found in watercraft or powersport applications. Besides the diameter, the woofer volume of 3.49 liters also plays a role in choosing the enclosure to ensure an ideal fit and acoustic performance.

Welche Vorteile bieten die ASA-Spritzgussteile des Prime RM112D2B?

The ASA injection molded parts used in the RM112D2B are 100% UV resistant, making them ideal for use in direct sunlight. ASA is known for its excellent color stability and high impact resistance, which is particularly important in marine applications. These materials provide long-term reliability and ensure that the speaker maintains its shape and function even under heavy external stress. The resistance to discoloration and adherence to structural integrity significantly contribute to the product's durability.

Wie beeinflusst der 2" Schwingspulendurchmesser des RM112D2B die Leistung?

The Prime RM112D2B is equipped with a 2-inch aluminum voice coil, which is responsible for the efficient conversion of electrical energy into sound waves. This size is ideal for both effectively dissipating heat and ensuring precise cone movement. A larger voice coil can handle more power, contributing to improved bass reproduction and the overall sound performance of the subwoofer. Such a design also allows for higher power handling and reduces the risk of distortion at high volumes.

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 .

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.

Top Upgrade für Canton System

Ich habe den Woofer in meinem Skoda Octavia 3 mit Canton Soundsystem eingebaut.
Der Einbau war Plug & Play, alles passt perfekt ohne Anpassungen.
Im Vergleich zum originalen Canton Subwoofer spielt dieser deutlich stärker, präziser und mit mehr Druck.
Ich kann den Woofer jedem empfehlen, der mehr Bass aus dem Canton-System herausholen möchte – lohnt sich absolut!
