Frequently Asked Questions about RS-KJ12

What are the dimensions of the RS-KJ12 and why are they important?

The overall dimensions of the RS-KJ12 from Reiss Audio are Ø318x194 mm. These measurements are crucial as they determine the installation in enclosures and vehicles specifically designed for Subwoofers. The right fit maximizes acoustic performance and minimizes vibrations. Especially for automotive applications, it is important to make optimal use of space in the trunk or under the car seat. By precisely following the dimensions of the RS-KJ12, it is ensured that the acoustic properties are not compromised, which is essential for sound quality.

What are the performance specifications of the Subwoofer RS-KJ12 from Reiss Audio?

The RS-KJ12 from Reiss Audio has an RMS power of 2000 watts, while its maximum power consumption is an impressive 4000 watts. These high power ratings make it ideal for demanding audio configurations where powerful bass is required. With a sensitivity of 84.3 dB, the Subwoofer is capable of producing a strong sound even at low input levels. These features are crucial if you want to fully exploit the potential of your audio system, especially for more intense music genres like electronic music or hip-hop.

What material is used for the cone of the RS-KJ12 and why?

The RS-KJ12 from Reiss Audio uses an unpressed paper cone with a treated foam surround. This choice of material offers several advantages: paper is known for its acoustic naturalness and lightness, leading to a fast and precise response. The additional coating with foam increases durability and controls the resonance characteristics. This combination allows for an optimized balance between stiffness and Damping, minimizing distortion and enhancing sound fidelity.

How does the voice coil of the RS-KJ12 affect performance?

The high-temperature voice coil of the RS-KJ12 measures 76.5 mm in diameter and is 38 mm high. Its construction with 4 layers and an aluminum coil body allows for high temperature resistance, thus extending operational life under extreme conditions. This voice coil ensures effective heat dissipation, minimizes the risk of thermal overload and distortion at high volumes. Additionally, it contributes to efficiency by optimizing the magnetic flux in the core area of the ferrite magnet structure, which sustainably supports the bass output.

What role does the magnet play in the RS-KJ12 and how is it constructed?

The RS-KJ12 Subwoofer utilizes a ferrite magnet system known for its durability and strength. The air gap of the magnet has a height of 14 mm, providing precise control over the diaphragm movement. This results in uniform drive of the voice coil, maximizing power consumption and minimizing sound distortion. The precisely tuned magnet mechanism allows for powerful bass reproduction that is effective at both low and high frequencies. This magnet structure is a key component for the robust performance of the RS-KJ12.

What impedances does the RS-KJ12 Subwoofer from Reiss Audio support?

The RS-KJ12 Subwoofer from Reiss Audio is designed for versatile impedance configurations, offering options of 2X2 Ohm or 2X4 Ohm. This allows for flexible integration into various audio systems to achieve either higher load capacity or lower resistance depending on the requirements. The former is useful for handling larger amplifier loads, while the latter is used for better drive in parallel speaker configurations. Such features enable optimal adjustment of the subwoofer to match one's amplifier and sound preferences.

What frequencies does the RS-KJ12 from Reiss Audio cover?

The frequency response of the RS-KJ12 ranges from 35 Hz to 500 Hz. This range is optimally designed for reproducing lower tones that a subwoofer should cover in an audio configuration. The lower limit allows for deep, rich bass reproduction, while the upper limit harmoniously transitions to midrange drivers. This makes the RS-KJ12 suitable for music styles that require deep, full bass and for demanding sound installations that require precision and definition across the entire frequency spectrum.

What is the moving mass of the RS-KJ12 and how does it affect performance?

The moving mass of the RS-KJ12 Subwoofer is 303 g or 295 g. This mass is crucial for the dynamic displacement of the diaphragm and directly influences bass reproduction and efficiency. An optimized mass allows for precision and control in movement, minimizing distortion and maximizing efficiency. Especially at high volumes or intense bass reproduction, adjusting this value ensures that the sound remains stable even under maximum pressure and that the performance of the Subwoofer is fully utilized.

What compatibility exists between the RS-KJ12 and car installations?

The RS-KJ12 from Reiss Audio has dimensions of Ø318x194 mm and is designed to be integrated into many car audio installations. The size is significant for installation in common 12-inch subwoofer enclosures, as often found in trunk or spare tire configurations. These dimensions facilitate adaptation in custom-made enclosures that provide the necessary volume space for optimal bass reproduction. However, it should always be checked that the available space in the vehicle is sufficient to avoid unwanted vibrations and resonances.

What compliance does the suspension of the RS-KJ12 have and why is this important?

The compliance of the suspension of the RS-KJ12 is 61.01 Cms or 71.2 Cms. These values are crucial as they determine how easily the diaphragm can move, which in turn affects the resonance frequency. An optimized compliance ensures precise and clear bass without distortion, even at high volumes. It regulates the balance between rigid control and flexibility, allowing the sub-chassis to remain both stable and low in resonance. This is of great importance for the sound quality and longevity of the entire Subwoofer unit.

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.
