Frequently Asked Questions about S2-W12D2/D4

What RMS and peak power does the Alpine S2-W12D2 Subwoofer offer?

The Alpine S2-W12D2 Subwoofer has a rated power of 600 Watts RMS and a peak power handling of 1800 Watts. These power ratings allow for powerful and stable bass reproduction that remains precise even at high volumes. With its high RMS power, the subwoofer can be operated continuously over longer periods without losing power or distorting. The peak power ensures that dynamic musical passages or bass-intensive film sequences can be reproduced without loss of quality, making it ideal for discerning audio enthusiasts.

What frequency range and sensitivity does the S2-W12D2 offer?

The Alpine S2-W12D2 Subwoofer has a frequency range of 23 Hz to 215 Hz, providing comprehensive bass coverage. With a sensitivity of 86 dB SPL@1 W/1 m, the subwoofer ensures clear bass reproduction even at low power. This wide frequency range allows the S2-W12D2 to accurately reproduce deep bass as well as mid-bass frequencies, which is beneficial for various music genres and audio applications. The high sensitivity helps the subwoofer operate efficiently and make optimal use of the available amplifier power.

How does the Alpine H.A.M.R. Surround technology improve the S2-W12D2 Subwoofer?

The Alpine High Amplitude Multi-Roll (H.A.M.R.) Surround technology in the S2-W12D2 ensures that the subwoofer cone moves air efficiently and is guided stably. This technology allows for a maximum excursion of up to 15 mm, resulting in increased power handling for the subwoofer. The H.A.M.R. surrounds simultaneously reduce unwanted resonances and distortions, leading to more precise bass reproduction. With improved stability, deeper and more powerful bass can be produced without compromising sound quality.

What materials are used for the diaphragm of the S2-W12D2?

The diaphragm of the Alpine S2-W12D2 Subwoofer is made from a lightweight yet robust combination of carbon fiber and polypropylene. This material choice ensures that the diaphragm delivers deep, distortion-free bass that emphasizes both the depth and fullness of the music. Carbon fiber provides high stiffness and low weight, enhancing the efficiency and responsiveness of the diaphragm. Polypropylene contributes to durability and resistance to mechanical stress, ensuring reliable performance over extended periods.

How does the dual voice coil with jumpers affect the flexibility of the S2-W12D2?

The dual voice coil (DVC) with practical jumpers in the Alpine S2-W12D2 Subwoofer allows for various configurations regarding impedance and power. By switching the jumpers, users can choose between 2Ω and 4Ω impedances, enhancing compatibility with different Amplifiers. This flexibility allows for optimal adaptation to existing audio systems and enables multiple Subwoofers to be connected in parallel or series to achieve either higher current or an extended range of installations. Thus, the S2-W12D2 can be seamlessly integrated into different systems.

How compatible is the Alpine S2-W12D2 with the Alpine S2-A60M and S2-A120M Amplifiers?

The Alpine S2-W12D2 Subwoofer is specifically tuned to the compatible Amplifiers of the Alpine S-Series. The S2-W12D2 can be easily operated with the 600 Watt mono Amplifier S2-A60M, allowing for a single Subwoofer installation with optimal sound quality. Alternatively, the S2-W12D2 can also be combined with the powerful 1200 Watt Amplifier S2-A120M, enabling multiple Subwoofers to be operated simultaneously. This perfect tuning guarantees maximum performance and stability, ensuring that bass reproduction remains precise and powerful.

What are the dimensions of the S2-W12D2 and what installation requirements should be considered?

The Alpine S2-W12D2 Subwoofer has a cutout diameter of 270 mm and a mounting depth of 124 mm. The installation height is only 25 mm, and the magnet diameter measures 155 mm. These compact dimensions allow for versatile installation in various vehicle types, while ensuring sufficient space in the trunk or other available areas. It is important to consider the installation dimensions and space constraints of the vehicle to ensure safe and effective integration of the Subwoofer without space issues.

How does the twist-lock grille mounting system of the S2-W12D2 work?

The Alpine S2-W12D2 Subwoofer features an innovative twist-lock grille mounting system that provides additional protection for the diaphragm. This system allows for easy attachment and removal of an optional cover grille without the need for fastening screws. The twisting motion securely fastens the grilles to the Subwoofer, allowing for quick and tool-free installation and maintenance. This mechanism protects the diaphragm from dust and mechanical influences without compromising the sound quality or ventilation of the Subwoofer.

What enclosure sizes are suitable for the S2-W12D2, sealed or vented?

The Alpine S2-W12D2 Subwoofer can be operated in both sealed and vented enclosures. For sealed enclosures, a volume between 17.3 and 34 liters is recommended, while vented enclosures provide a volume of 30 to 45.3 liters. The choice of enclosure type affects bass reproduction: Sealed enclosures offer more precise bass reproduction with faster response time, while vented enclosures allow for deeper and more powerful bass. The enclosure size and design should be selected according to individual sound preferences and space conditions in the vehicle.

How does the combination of carbon fiber and polypropylene optimize the sound quality of the S2-W12D2?

The combination of carbon fiber and polypropylene in the membrane of the Alpine S2-W12D2 Subwoofer provides an optimal balance between lightness and robustness. Carbon fiber gives the membrane high stiffness and allows for quick vibrations, improving the response time and accuracy of bass reproduction. Polypropylene ensures lower distortion and increases the durability of the subwoofer under high load. This material synergy results in deep, clear, and distortion-free bass that significantly enhances the overall sound quality of the sound system.

What connection options does the S2-W12D2 Subwoofer offer for flexible installation?

The Alpine S2-W12D2 Subwoofer is equipped with pressure terminals that support cable cross-sections up to 8 mm². This allows for a secure and stable connection with amplifiers and other audio components. The dual voice coil (DVC) with jumpers facilitates impedance configuration, enabling various installation scenarios. Additionally, the twist-lock grille mounting system provides easy and tool-free installation, making the installation and maintenance of the subwoofer more flexible. These connection options ensure easy integration into existing systems and allow for individual adjustments to specific requirements.

Es lohnt sich!

Ich habe sie an den Sounddigital 800.4 Evo6 angeschlossen. Und ich bin mehr als zufrieden. Mitteltöner laut und auch präzise. Hochtöner brennen nicht in den Ohren, die sind laut und geben das, was sie sollen. Gut angelegtes Geld.

Laut ... einfach nur laut

Also ich sag es mal so... wenn man ein Lautes Kompo System sucht, mit noch sehr guten Klangeigenschaften.
Naja der sollte das T3 von Rockford nehmen.
Ich hatte viele Systeme verbaut und bin dann wieder zurück zum T3 und habe nun 3 verbaut... schön laut und sehr feiner Klang.

vibe powerbox65.4m v7 samen met quadlock connector besteld.

Levertijd prima in orde.

vibe powerbox65.4m v7 in mijn vrachtwagen Volvo Fmx 2024 gemonteerd met Quadlock.
Alleen plug and play super fantastisch systeem. Alles standaard op 12v geen omvormer of iets nodig.
In bouw tijd ongeveer 30 minuten.
Radio verwijderen connectors verbinden vibe powerbox65.4m v7 aansluiten.
Alle originele radio instellingen op nul of uit gezet. Volume op 3/4 langzaam de powerbox65.4m v7 open draaien en al het werk laten doen.
Perfect kristal helder geluid in combinatie met mijn Rockford t142 en Rockford p1650 speakers. De bass geluid is verbeterd maar voor echte diepe baas waar ik persoonlijk niet zo van ben heb je echt een externe subwoofer nodig.
Kortom een goede upgrade van je radiogeluid is gegarandeerd.

Masori was goed met de prijs, perfecte communicate met hun gehad. Een echte aanrader.
