Mercedes-Benz CLS400 Front Door Panel Speaker Size
The Mercedes-Benz CLS400 front door panel accommodates a 6.5 inch speaker size across all listed model years. Compatible audio types for the location include midbass and full-range replacement units. The specifications cover a range of years from 2015 to 2017.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Midbass / Full-Range | 6.5 |
| 2016 | Midbass / Full-Range | 6.5 |
| 2015 | 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 front door panel location in the Mercedes-Benz CLS400 places speakers within the lower portion of the door cavity, positioning the driver toward the listener's foot and knee level.
- Door panel mounting at this height means sound travels upward toward the listening position, which affects the perceived stereo imaging and localization of lower frequencies.
- A 6.5 inch driver in a front door panel occupies a mid-sized footprint, requiring a mounting depth and baffle cutout consistent with standard aftermarket and OEM door speaker configurations.
- The 6.5 inch cone diameter produces a surface area suited to moving sufficient air for lower-midrange and upper-bass reproduction, which are the frequency ranges most naturally reinforced by door cavity acoustic coupling.
- The door cavity itself acts as an enclosure that influences the low-frequency extension of a 6.5 inch driver, with the internal volume and panel material affecting resonance behavior.
- A midbass driver in the front door panel of the Mercedes-Benz CLS400 is designed to handle the lower-midrange and bass frequencies, typically operating in a range from approximately 80 Hz to 500 Hz, leaving upper frequencies to other drivers in a multi-component system.
- A full-range driver covers a broader frequency span from low bass through high treble within a single cone, making the front door panel the sole or primary sound source for the full audible spectrum when a full-range type is used.
- Midbass drivers are generally designed without a dust cap tweeter and with a surround and spider optimized for longer excursion, which suits the bass-reinforcing acoustics of a door panel cavity.
- Full-range drivers in a door panel location must project high-frequency content from a low mounting point, which can reduce treble directivity toward the listener's ear level.
- The 6.5 inch size remains consistent across the 2015, 2016, and 2017 model years, indicating a stable physical mounting configuration across the listed production span of the CLS400.
