Mercedes-Benz E400 Rear Door Panel Speaker Size
The Mercedes-Benz E400 rear door panel accommodates a 6.5 inch speaker size across all listed model years. Compatible types for the audio system include midbass and full-range replacement units. These specifications cover the 2013 to 2015 model year chart range.
| Year | Type | Size (inch) |
|---|---|---|
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | Midbass / Full-Range | 6.5 |
| 2013 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| 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 E400 accommodates speakers mounted within the door cavity, where the speaker cone faces inward toward the cabin and sound projection is directed across the passenger seating area.
- Door panel installations are subject to spatial constraints imposed by the door's internal architecture, including window mechanisms, structural reinforcements, and wiring harnesses, all of which define the maximum allowable speaker depth and diameter.
- A 6.5 inch driver occupies a mid-sized diameter category that balances cone surface area with the physical depth restrictions common to door panel cavities, making cone excursion and low-frequency extension more feasible than smaller-diameter alternatives while remaining within typical door mounting tolerances.
- The 6.5 inch cone area enables greater air displacement compared to smaller drivers, which is mechanically significant in rear door locations where lower-midrange and upper-bass reproduction are acoustically relevant to rear-seat listeners.
- Midbass is a speaker type defined by a designed operating range that prioritizes frequencies roughly between 80 Hz and 500 Hz, covering the upper bass and lower midrange bands where male vocals, bass guitar fundamentals, and kick drum body are reproduced.
- In a rear door panel position, a midbass driver receives audio energy that fills the lower portion of the audible spectrum for rear-seat occupants, with the door cavity itself acting as an enclosure that influences bass loading and overall output character.
- Full-range is a speaker type engineered to reproduce a wider span of the audible frequency spectrum from bass through treble within a single driver, typically incorporating a whizzer cone or similar mechanism to extend high-frequency output.
- When a full-range driver is installed in the Mercedes-Benz E400 rear door panel location, the directional dispersion of higher frequencies from the cone is influenced by the angle and depth of the door-mounted baffle, which affects how treble energy reaches rear-seat listeners.
- The rear door panel placement positions the speaker at roughly seat-level height for rear passengers, a geometry that affects imaging and the perceived direction of sound relative to ear height.
- Both midbass and full-range types are listed as compatible for the 6.5 inch opening across the 2013, 2014, and 2015 model years, indicating the physical mounting recess dimensions remain consistent across those production years.
