The C1C165AM-04-770 / FG is a high-performance mid-bass driver that stands out due to its adaptation to humid, temperature, and vibration-rich environments in the automotive sector. Its frequency range extends from 35 Hz to 2800 Hz in a sealed box. It features a high-flow neo overhang motor and an extended Xmax design that enables ultra-high dynamic and high-resolution applications. The sensitivity is 91 dB at 2.83 V/1 m. With a moving mass (Mms) of 19 g and a voice coil diameter of 55 mm, as well as a force factor (Bl) of 8 N/A, its performance specifications are remarkable. Its voice coil material consists of copper with a Ti coil carrier.

What are the dimensions of the C1C165AM-04-770 / FG speaker?

The dimensions of the C1C165AM-04-770 / FG are essential for proper installation in the vehicle. The overall diameter is 165 mm, the cutout diameter is 142 mm, while the minimum front plate thickness is 6.5 mm. The total depth of the speaker measures 88.5 mm, with the motor assembly measuring 29 mm in depth and 100 mm in diameter. These compact dimensions allow for easy integration into various car models, provided that appropriate cutouts are available. When installing, the installation conditions must be observed to ensure the best possible sound quality.

What Thiele-Small parameters does the C1C165AM-04-770 / FG offer?

The C1C165AM-04-770 / FG is equipped with detailed Thiele-Small parameters that define its acoustic performance. The resonance frequency (Fs) is 40 Hz, while the equivalent air volume (Vas) is 21 liters. The mechanical quality factor (Qms) is 5, the electrical quality factor (Qes) is 0.3, and the total quality factor (Qts) is 0.29. The effective piston area (Sd) is 133 cm². Additionally, the speaker shows a voice coil inductance (Le) of 0.5 mH and a mechanical resistance (Rms) of 0.98 kg/s. These parameters are crucial for the speaker's performance in the specific acoustic environment.

What is the maximum linear excursion (Xmax) of the C1C165AM-04-770 / FG?

The C1C165AM-04-770 / FG offers a maximum linear excursion (Xmax) of +/- 6 mm. This extended Xmax design allows the speaker to produce high sound pressure without distortion. The voice coil has a diameter of 55 mm and the material is made of copper, which combines high conductivity with a robust physical structure. An extended maximum excursion range is particularly advantageous for dynamic and complex musical pieces to accurately and powerfully reproduce low frequencies, making it an excellent choice for sound-conscious drivers.

How does the high-flow Neo overhang motor affect the performance of the C1C165AM-04-770 / FG?

The high-flow Neo overhang motor of the C1C165AM-04-770 / FG plays a crucial role in providing the power required for ultra-high dynamic applications. This specially designed motor supports the motion control of the speaker and enhances the restoring force of the diaphragm, resulting in extremely low distortion values. The use of neodymium magnets significantly increases the magnetic flux density, maximizing overall performance and efficiency. Especially in combination with the precise voice coil, sound definition is greatly enhanced, which is essential for demanding high-end acoustic applications in automobiles.

Is the C1C165AM-04-770 / FG compatible with specific car models?

The C1C165AM-04-770 / FG is universally suitable for numerous vehicle configurations, with its dimensions playing a central role. With an outer diameter of 165 mm and a cutout diameter of 142 mm, it fits most standardized 6.5-inch installation openings in vehicles. Due to its shallow installation depth of 88.5 mm, the speaker can also be integrated in tight spaces. The generic dimensions make it a flexible solution; however, checking the exact installation conditions in individual vehicle models is necessary to ensure optimal acoustic performance.

What does the sensitivity of 91 dB mean for the C1C165AM-04-770 / FG?

The sensitivity of the C1C165AM-04-770 / FG speaker of 91 dB (measured with 2.83 V/1 m) indicates how efficiently the speaker converts sound into audible volume. A higher dB value means that the speaker plays louder at the same power input. This is particularly important when the speaker is powered by an amplifier or a car hi-fi system, as it requires less power to produce a high volume. This efficiency is a clear advantage, especially for users who listen to music loudly, as the speaker excels with less amplifier output.

How are the suspension compliance and mechanical resistance defined for the C1C165AM-04-770 / FG?

The suspension compliance (CMS) of the C1C165AM-04-770 / FG is 0.8 mm/N, indicating the compliance of its diaphragm suspension, which plays a significant role in low-frequency reproduction. The mechanical resistance (Rms) is 0.98 Kg*s, meaning that the mechanical losses of the system are minimized, resulting in less energy lost as heat and other loss factors. Both parameters are essential for accurately and efficiently shaping the acoustic performance of the speaker by optimizing the control and restoring force of the diaphragm, ultimately enhancing overall sound precision.

How does the voice coil material affect the sound quality of the C1C165AM-04-770 / FG?

The voice coil material of the C1C165AM-04-770 / FG, copper (Cu), offers excellent conductivity and contributes to a high thermal capacity of 120 W. The choice of material directly influences sound quality through its ability to dissipate heat efficiently, improving the performance and lifespan of the speaker. The Ti former provides additional thermal control and stabilization in demanding acoustic environments. This combination is particularly advantageous in applications where high output levels and continuous operation are required, as it minimizes distortion and ensures detailed and undistorted sound.

What frequency range does the C1C165AM-04-770 / FG cover?

The C1C165AM-04-770 / FG speaker from Accuton Automotive offers an impressive frequency range of 35 Hz to 2800 Hz when used in a sealed enclosure. This bandwidth allows for efficient and clear reproduction of deep bass and midrange frequencies, making the device an ideal component for high-quality car audio systems. Its ability to reproduce low frequencies with minimal distortion makes it an essential part of applications that require high-resolution and dynamic sound reproduction. This ensures that both vocals and instruments are reproduced in remarkable quality.

Superlee
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.

Used as replacement to Škodas canton system

Used as replacement to Škodas canton system subwoofer.
Works great, fits right into the factory box, need to remove only one little pin and use new skrews.
Sound is even better then it was before.
Plug and play for that system.

Richtig guter Tiefmitteltöner mit Alu-Gusskorb

Richtig guter Tiefmitteltöner mit Alu-Gusskorb und um 30Hz niedrigerer Resonanzfrequenz als üblich im 10cm-Woofer-Bereich. Dadurch kann sich dieser 10cm-Woofer auch wirklich Tiefmitteltöner nennen.

Real power

Ziet er goed uit,Heb 2 accu`s aangesloten, Daar tussen Stinger scheidingsrelais van 200 amp,
Ook moet je 2x zekering van 200 amp plaatsen,

Heb bewust voor Stinger 200 ampere gekozen omdat ik een standaard dynamo heb is dat voldoende.
