Mercedes-Benz C240 Rear Door Panel Speaker Size
The Mercedes-Benz C240 rear door panel accommodates a 1 inch speaker size and 6.5 inch speakers across the model's production span. Compatible types for these units include tweeters and midbass or full-range audio components within the system. These specifications cover the 2001 to 2005 model years.
| 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 positions speakers within an enclosed cavity mounted at ear level for seated rear passengers, with the speaker baffle oriented toward the cabin interior.
- Door panel installations typically involve limited depth clearance behind the mounting surface, which affects the magnet and basket dimensions of any speaker placed in the location.
- A 6.5 inch driver in the rear door panel occupies a mid-to-large diameter mounting cutout, a size associated with the reproduction of lower midrange and upper bass frequencies, generally spanning from approximately 60 Hz to 5 kHz depending on cone material and crossover configuration.
- The midbass designation for the 6.5 inch position indicates a driver role focused on the frequency band between bass and midrange, roughly 80 Hz to 500 Hz, which in a rear door panel benefits from the acoustic coupling between the speaker and the door cavity acting as a partial enclosure.
- The full-range designation for the 6.5 inch position indicates a driver capable of reproducing a wider portion of the audible spectrum without a dedicated crossover, covering bass, midrange, and limited high-frequency content from a single cone.
- The 1 inch tweeter specification, listed exclusively for the 2005 Mercedes-Benz C240 rear door panel, places a high-frequency driver within the same door location as the 6.5 inch driver, indicating a 2-way speaker arrangement at the rear door.
- A 1 inch tweeter dome diameter is standard for high-frequency reproduction, typically handling frequencies from approximately 2 kHz to 20 kHz, with the small diaphragm size enabling wide dispersion of treble frequencies across the rear cabin.
- Tweeters mounted in door panels radiate high frequencies from a low position relative to seated passengers, which influences the perceived soundstage height and directionality of treble content in the rear seating area.
- The 6.5 inch driver present across the 2001 through 2005 model years maintains a consistent mounting cutout diameter, indicating dimensional continuity in the rear door panel speaker opening across the full production span covered in the specifications.
- Door panel mounting surfaces in sedans like the C240 are typically constructed from molded plastic with a speaker grille integrated into the panel, which can influence the acoustic transparency and diffraction characteristics of sound exiting the driver.
