Mercedes-Benz C320 Rear Door Panel Speaker Size
The Mercedes-Benz C320 rear door panel accommodates a 1 inch speaker size and 6.5 inch speakers across the model's production span. Compatible types for the locations include tweeters and midbass / full-range units. These specifications cover the years 2001 through 2005.
| Year | Type | Size (inch) |
|---|---|---|
| 2005 | Tweeter | 1 |
| 2005 | Midbass / Full-Range | 6.5 |
| 2004 | Midbass / Full-Range | 6.5 |
| 2003 | Midbass / Full-Range | 6.5 |
| 2002 | Midbass / Full-Range | 6.5 |
| 2001 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| Tweeter | A small driver built for high frequencies, typically from about 2,000 Hz to 20,000 Hz. It adds treble detail and clarity and is usually mounted near ear level or aimed at the listener. |
| 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 in the Mercedes-Benz C320 accommodates speakers mounted within the door's interior trim panel, a position that places drivers at a low angle relative to seated passengers and at a moderate distance from the listening position.
- Door panel mounting orients speaker cones toward the cabin interior, though the low position typical of rear door installations means sound travels upward and across the cabin rather than directly at ear level.
- The 6.5 inch diameter is present across all listed model years for the rear door panel, indicating a consistent cutout size within the door panel cavity throughout the C320's production run covered by these specifications.
- A 6.5 inch driver in a rear door panel location operates effectively in the midbass range, reproducing lower midrange and upper bass frequencies where door panel placement and panel resonance characteristics are most relevant.
- The midbass role of a 6.5 inch speaker in a door panel involves reproducing frequencies roughly between 80 Hz and 500 Hz, a range that benefits from the larger cone surface area relative to smaller drivers.
- Full-range compatibility for the 6.5 inch position means a single driver in the rear door panel can cover both the midbass region and extended midrange frequencies without a dedicated supplemental driver in that location, depending on the chosen speaker.
- The 1 inch tweeter specification appears exclusively in the 2005 model year, indicating a second, separate speaker mounting location within the 2005 C320 rear door panel distinct from the 6.5 inch position.
- The Mercedes-Benz C320 2005 rear door panel tweeter position accommodates a 1 inch driver, a size associated with high-frequency reproduction typically beginning around 2,000 Hz and extending through the upper limits of human hearing.
- A 1 inch tweeter in a rear door panel location disperses high-frequency content into the rear cabin, where the mounting height within the door panel influences the directional arrival angle of treble frequencies at passenger ear level.
- Tweeters, as a speaker type, are designed exclusively for high-frequency reproduction and are not suited to handle midbass or low-midrange content, functioning in the rear door panel as a high-end complement rather than a broadband driver.
- The 6.5 inch driver's relatively larger cone mass compared to a 1 inch tweeter makes the larger format less suited for reproducing the rapid transient movements required by high frequencies, which is why both sizes are listed separately for the 2005 rear door panel.
