Mercedes-Benz E400 Rear Side Panel Speaker Size
The Mercedes-Benz E400 rear side panel accommodates a 1 inch speaker size across all listed model years. Tweeter units are the compatible audio replacement type for the system at that location. These specifications cover the 2015 to 2017 model year range.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Tweeter | 1 |
| 2016 | Tweeter | 1 |
| 2015 | Tweeter | 1 |
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. |
Additional Notes
- The rear side panel location in the Mercedes-Benz E400 accommodates a 1-inch speaker diameter across the 2015, 2016, and 2017 model years.
- A 1-inch diameter is a standard dimension for tweeter drivers, reflecting the compact cone or dome surface area required to move air efficiently at high frequencies.
- Tweeters are high-frequency transducers, typically reproducing audio content in the range above approximately 2,000 Hz, where wavelengths are short enough to be handled by a small diaphragm.
- The rear side panel is a fixed, enclosed mounting surface within the vehicle's cabin wall, positioning the driver toward the passenger compartment rather than the floor or ceiling.
- A side panel placement orients the tweeter's dispersion axis laterally, which affects the high-frequency soundfield experienced by rear-seat occupants.
- Tweeters have a relatively narrow dispersion pattern at the upper end of their frequency range, meaning the mounting angle of a rear side panel installation influences how directly high frequencies reach listeners in adjacent seating positions.
- The 1-inch form factor limits the physical depth and diameter of the speaker cutout required in the side panel, which corresponds to the typically shallow mounting depth of tweeter assemblies.
- At the rear side panel location, a tweeter does not reproduce bass or midrange content, as those frequency ranges require larger cone areas and greater excursion than a 1-inch driver is designed to deliver.
