Mercedes-Benz E400 Front Door Panel Speaker Size
The Mercedes-Benz E400 front door panel accommodates a 1 inch speaker size and 6.5 inch speakers. Compatible types across these locations include tweeter and midbass / full-range units. The specifications cover the years 2013 to 2017.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Tweeter | 1 |
| 2017 | Midbass / Full-Range | 6.5 |
| 2016 | Tweeter | 1 |
| 2016 | Midbass / Full-Range | 6.5 |
| 2015 | Tweeter | 1 |
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | Midbass / Full-Range | 6.5 |
| 2013 | 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 Mercedes-Benz E400 front door panel accommodates 2 distinct speaker sizes across the listed model years: 1 inch and 6.5 inch.
- The front door panel location positions speakers within the lower-to-mid section of the cabin door, where the baffle is integrated into the door's inner trim structure.
- A 6.5 inch driver in a front door panel occupies a mounting cavity that is typically recessed into the door's inner skin, using the door's internal volume as a passive acoustic chamber.
- The 6.5 inch size supports midbass and full-range operation, covering approximately 80 Hz to 5 kHz, which in a front door location means the driver handles the primary low-to-midrange content directed toward the passenger cabin.
- Midbass drivers in a front door are dedicated to the lower midrange and upper bass frequencies, typically crossed over so high-frequency content is handled separately, reducing cone excursion stress and improving clarity in the mid frequencies.
- Full-range drivers at 6.5 inches reproduce the entire audible spectrum from a single cone, which in a front door panel means a single mounting position covers bass, midrange, and a portion of the high-frequency content without a separate tweeter.
- The 1 inch tweeter size is listed for the 2015, 2016, and 2017 model years within the same front door panel location, indicating a multi-driver configuration in the door for those years.
- A 1 inch tweeter operates in the high-frequency range, generally from around 2 kHz to 20 kHz, with the small diaphragm diameter enabling accurate reproduction of transients and high-frequency detail.
- Tweeters mounted in a front door panel position the high-frequency dispersion point at a lower height than dashboard or A-pillar placements, which affects the perceived soundstage height within the cabin.
- The directional behavior of a 1 inch tweeter is relatively wide at lower treble frequencies and becomes increasingly narrow at higher frequencies, a characteristic relevant to front door placement where the driver faces toward the passenger seats at an angle.
- For the 2013 and 2014 model years, the front door panel specification lists only the 6.5 inch position, without a corresponding 1 inch tweeter entry, indicating a single-driver mounting location in the door for those years.
- The coexistence of a 1 inch tweeter and a 6.5 inch midbass or full-range driver within the same front door panel in the 2015-2017 Mercedes-Benz E400 reflects a front door design with at least 2 separate speaker cutouts or mounting points.
