Mercedes-Benz C400 Rear Door Panel Speaker Size
The Mercedes-Benz C400 rear door panel accommodates a 6.5 inch speaker size. Compatible types for the location include midbass and full-range audio system units. These specifications cover the 2015 model year.
| Year | Type | Size (inch) |
|---|---|---|
| 2015 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| Midbass | A driver tuned for upper bass and lower midrange, roughly from 80 Hz to 500 Hz. It has longer cone travel than a full-range unit, which supports stronger bass in doors and panels. |
| Full-Range | A single driver that reproduces bass through treble without a separate crossover network. It is the simplest replacement option and is common in factory audio systems. |
Additional Notes
- The rear door panel location positions speakers within the lower portion of the door, where the enclosure is formed by the door cavity and panel surface, influencing both bass reinforcement and midrange projection toward the cabin.
- A 6.5 inch driver in the rear door panel of the Mercedes-Benz C400 occupies a mounting diameter that accommodates sufficient cone area for extended low-frequency reproduction while remaining within the spatial constraints of the door cavity.
- Door panel installations typically require attention to mounting depth, as the inner door structure limits how far a speaker basket can protrude before contacting the door's metal framework or window mechanism.
- The 6.5 inch cone diameter produces a surface area that generates meaningful air displacement, which is a mechanical prerequisite for producing midbass frequencies in the 80 Hz to 500 Hz range.
- A midbass driver is a transducer designed to reproduce the lower midrange and upper bass frequencies, typically operating between approximately 80 Hz and 500 Hz, and is not optimized for high-frequency detail or deep sub-bass extension.
- In a rear door panel location, a midbass driver functions as a source of low-frequency body and warmth directed toward the rear cabin seating area, where door placement provides a degree of boundary reinforcement from the door structure itself.
- A full-range driver is designed to reproduce a broad frequency spectrum from bass through treble within a single cone, making the 6.5 inch size a functional fit for rear door panel positions where a single driver must handle all audible frequencies without a crossover network.
- The 6.5 inch size in a door panel application typically requires a mounting depth ranging from approximately 2 to 3 inches depending on the specific driver, and the rear door cavity of the C400 for the 2015 model year must accommodate that depth without obstruction.
- Rear door panel speakers operate at a greater distance from front-seat listeners compared to front door installations, which affects the time-arrival relationship of sound and the perceived stereo imaging within the cabin.
- The angular orientation of a driver mounted in the rear door panel is generally angled toward the interior seating area rather than firing directly upward or rearward, which shapes the directional dispersion of midrange frequencies within the cabin.
