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. |
| 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. |
| 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 front door panel of the Mercedes-Benz E350 is a multi-driver location, with specifications listing as many as 3 distinct speaker positions within the same model year.
- Door panel installations are typically recessed into cavities within the inner door structure, meaning cone excursion, depth clearance, and baffle dimensions are all governed by the physical constraints of the door's interior architecture.
- The 1 inch tweeter present across all listed model years handles high-frequency reproduction, generally covering the range above approximately 2,000-5,000 Hz. Mounted in a door panel, a 1 inch tweeter benefits from placement closer to ear level than floor-mounted positions, which supports high-frequency directionality since treble energy is highly directional and attenuates sharply off-axis.
- The 3.5 inch midrange driver, listed for model years 2017 through 2023, occupies the upper portion of the mid-frequency band, typically spanning roughly 500 Hz to 5,000 Hz. A 3.5 inch cone has a relatively small radiating area, which limits low-frequency extension but allows tighter control over midrange directivity in the confined acoustic environment of a door panel.
- The 4 inch midrange driver, listed for 2024 and 2025, covers a similar frequency band to the 3.5 inch but with a modestly larger diaphragm area, which can support slightly greater output efficiency in the same midrange band within the door panel cavity.
- The 6.75 inch midbass/full-range driver, listed for model years 2017 through 2023, carries a larger cone diameter suited to reproducing lower midrange and upper bass frequencies, generally from around 60-80 Hz up through the midrange. In a door panel, a 6.75 inch driver requires sufficient depth and baffle area, and the door cavity can serve as an acoustic enclosure that influences low-frequency loading on the cone.
- The 6.5 inch midbass/full-range driver, listed for model years 2006 through 2016, serves the same low-to-mid frequency role as the 6.75 inch but within a slightly smaller footprint. The difference of 0.25 inches in diameter corresponds to a measurable reduction in cone surface area, which affects the volume of air the driver can move at the door panel location.
- For model years 2015 and 2016, the specifications list only the 6.5 inch midbass/full-range driver at the front door panel location, with no additional tweeter or midrange driver listed for those years.
- The front door panel location places speakers inside a sealed or semi-sealed structural cavity, and the internal volume of a car door can act as a rear enclosure for midbass and full-range drivers, affecting the resonant behavior and low-frequency response of 6.5 inch and 6.75 inch drivers installed there.
- A full-range designation on the 6.5 inch and 6.75 inch drivers indicates a driver rated to reproduce a wide frequency band on its own, though when paired with a tweeter and midrange in the same door panel, the full-range capability of the larger driver is typically supplemented rather than used in isolation.
- The Mercedes-Benz E350 front door panel transitions from a 2-driver configuration (tweeter + midbass/full-range) seen in multiple earlier years to a 3-driver configuration (tweeter + midrange + midbass/full-range) beginning with the 2017 model year through 2023, before returning to a 2-driver configuration in 2024 and 2025 with a 4 inch midrange replacing the separate midbass/full-range driver.
- The mounting diameter difference between a 6.5 inch and a 6.75 inch driver means the two sizes are not directly interchangeable at the front door panel location without accounting for the difference in cutout diameter and mounting hole pattern.
