Mercedes-Benz C280 Rear Door Panel Speaker Size
The Mercedes-Benz C280 rear door panel accommodates 1 inch speaker size units, 6.5 inch speakers, and 4 inch speakers. Compatible types across these locations include tweeters, midbass, full-range, and midrange audio system components. These specifications cover a range from 2000 to 2007.
| Year | Type | Size (inch) |
|---|---|---|
| 2007 | Tweeter | 1 |
| 2007 | Midbass / Full-Range | 6.5 |
| 2006 | Tweeter | 1 |
| 2006 | Midbass / Full-Range | 6.5 |
| 2000 | Midrange | 4 |
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. |
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
| 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 places speakers within the lower portion of the vehicle's interior doors, a position that affects low-frequency reinforcement due to proximity to floor-level acoustic boundaries and cabinet-like door cavity enclosures.
- For the 2006 and 2007 Mercedes-Benz C280, the rear door panel accommodates 2 distinct speaker sizes simultaneously - 1 inch and 6.5 inch - indicating a multi-driver configuration within the same door panel location.
- The 6.5 inch diameter is a mid-to-large cone driver size; in a rear door panel context, the physical cone area supports reproduction of lower-midrange and upper-bass frequencies, where the door cavity acts as a partial acoustic enclosure influencing bass output.
- A midbass driver in the 6.5 inch position at the rear door panel handles the frequency overlap between bass and midrange, typically operating across roughly 80 Hz to 500 Hz, contributing to the perceived warmth and body of the overall sound stage.
- A full-range driver of 6.5 inches covers a wider frequency span from low bass through upper midrange, relying on a single cone to reproduce content that a multi-driver system would otherwise divide among separate components.
- The 1 inch tweeter size is a small, high-frequency driver; at the rear door panel position, the mounting height is relatively low compared to a dashboard or A-pillar location, which affects the perceived directionality of high-frequency content reaching the listening area.
- Tweeters reproduce frequencies generally above 2,000 Hz, where sound waves are highly directional and strongly influenced by the angle between the driver and the listener's ears - a relevant factor when the driver is mounted in a low rear door panel position.
- The 2000 model year rear door panel accommodates a single 4 inch driver size, which is smaller in cone diameter than the 6.5 inch used in later years, resulting in a more limited low-frequency extension from the same door panel location.
- A 4 inch midrange driver operates across the vocal and instrument presence frequencies, typically from approximately 300 Hz to 5,000 Hz, and in a rear door panel enclosure the door cavity contributes to the acoustic loading around the lower end of that range.
- The midrange type designation for the 4 inch driver in the 2000 model year indicates a driver optimized for clarity in the mid frequencies rather than extended bass reproduction, consistent with the physical limitations of a smaller cone area at a door panel mounting point.
