Mercedes-Benz E320 Rear Deck Lid Speaker Size
The Mercedes-Benz E320 rear deck lid can accommodate a 1 inch speaker size and 6.5 inch speakers, reflecting the 2 unique sizes found across the model's production span. Compatible types for the location include tweeters and midbass or full-range units. These specifications cover the years 2000 through 2009.
| Year | Type | Size (inch) |
|---|---|---|
| 2009 | Tweeter | 1 |
| 2008 | Tweeter | 1 |
| 2007 | Tweeter | 1 |
| 2002 | Midbass / Full-Range | 6.5 |
| 2001 | Midbass / Full-Range | 6.5 |
| 2000 | 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 deck lid is a horizontal surface positioned at the rear of the cabin, typically flush-mounted behind the rear seating area and beneath the rear window, placing speakers in a rearward-facing or upward-facing orientation relative to the passenger compartment.
- Mounting depth and baffle space on a deck lid are generally shallow, which constrains the physical profile of compatible drivers and influences the enclosure characteristics available to the installed speaker.
- The 1-inch tweeter size specified for the 2007, 2008, and 2009 Mercedes-Benz E320 rear deck lid reflects a driver designed to reproduce high-frequency content, typically operating in a range above approximately 2,000 Hz to 3,000 Hz and extending toward the upper limits of human hearing.
- A 1-inch tweeter dome radiates high-frequency sound with relatively wide dispersion, which, when mounted on the rear deck lid, distributes treble energy upward and forward into the cabin rather than projecting it directly at seated passengers.
- The rear deck lid position for a tweeter places the driver at a distance from front-seat listeners, which can affect the time-alignment relationship between the tweeter and any front-mounted speakers in a multi-driver system.
- The 6.5-inch driver size specified for the 2000, 2001, and 2002 model years is associated with a cone diameter capable of moving enough air to reproduce mid-frequency and lower-mid-frequency content effectively, generally covering a range from approximately 60 Hz to 5,000 Hz depending on driver design.
- A midbass driver in the 6.5-inch format handles the frequency region between bass fundamentals and upper midrange, reinforcing the body and warmth of audio content from the rear deck lid position.
- A full-range driver of 6.5 inches is designed to cover the broadest practical frequency span for a single cone driver, extending from lower bass frequencies through treble without a crossover, making it a standalone solution for the rear deck lid location.
- The rear deck lid location, being near the rear window and trunk cavity, can introduce acoustic coloration due to boundary reflections from the glass and the trunk enclosure behind the mounting surface, which affects both the 1-inch and 6.5-inch driver configurations.
- The transition between the 6.5-inch midbass/full-range configuration in the 2000-2002 model years and the 1-inch tweeter-only configuration in the 2007-2009 model years reflects a change in the acoustic role assigned to the rear deck lid position across the E320's production generations.
