Mercedes-Benz E400 Rear Deck Lid Speaker Size
The Mercedes-Benz E400 rear deck lid accommodates a 2.75 inch speaker size across all listed model years. Compatible types for these units include midrange audio components suited to the system. These specifications cover the 2015 to 2017 range of model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Midrange | 2.75 |
| 2016 | Midrange | 2.75 |
| 2015 | Midrange | 2.75 |
Speaker Types
| Type | Description |
|---|---|
| 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. |
Additional Notes
- The rear deck lid location in the Mercedes-Benz E400 accommodates a 2.75-inch speaker opening across the 2015, 2016, and 2017 model years.
- A 2.75-inch driver occupies a compact footprint, making the rear deck lid a spatially constrained mounting position with limited cone surface area available for sound reproduction.
- The shallow depth typical of rear deck lid cavities in sedan body styles restricts the available mounting depth, which is a relevant dimensional factor for selecting a compatible 2.75-inch driver.
- The rear deck lid sits at the rearmost section of the cabin, behind the rear seating, placing the speaker some distance from front-seat occupants and in close proximity to rear-seat passengers.
- At 2.75 inches, the cone diameter limits low-frequency excursion capability, positioning the driver acoustically within the upper-bass and midrange portion of the audible spectrum.
- Midrange drivers are designed to reproduce frequencies roughly spanning 500 Hz to 5,000 Hz, covering the vocal presence range and much of the harmonic content of musical instruments.
- The midrange type specification for the Mercedes-Benz E400 rear deck lid indicates the location is not intended to handle full-range or subwoofer-level output, but rather focused mid-frequency reproduction.
- A 2.75-inch midrange driver in a rear deck lid position contributes to rear fill by reinforcing vocal and mid-frequency content toward the back of the cabin.
- Midrange drivers typically use a relatively stiff cone or dome construction to maintain controlled directional dispersion across the frequencies the driver reproduces, which affects how sound radiates within the enclosed rear cabin section.
- The small cone area of a 2.75-inch driver results in higher sensitivity to precise enclosure volume behind the mounting surface, meaning the rear deck lid cavity dimensions directly influence the acoustic behavior of the installed driver.
