Mercedes-Benz CLS400 Rear Door Panel Speaker Size
The Mercedes-Benz CLS400 rear door panel accommodates a 6.5 inch speaker size across all listed model years. Compatible types for the location include midbass and full-range audio units. The specifications cover a range of 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 rear door panel location on the Mercedes-Benz CLS400 houses a single speaker position per door, mounted within the door panel cavity where the speaker baffle faces the cabin interior.
- Door panel installations are subject to spatial constraints from the door card structure, window mechanisms, and interior trim, which collectively define the maximum cone diameter and depth that can be accommodated in the opening.
- A 6.5 inch speaker diameter represents a mid-sized woofer format commonly associated with rear door panel applications, where the door cavity provides sufficient depth and baffle area to support a cone of that diameter without interference from internal door hardware.
- In a rear door panel position, a 6.5 inch driver operates within a partially enclosed cavity formed by the door skin and inner panel, which affects the rear wave behavior of the speaker and influences low-frequency extension.
- The 6.5 inch size in a rear door location is acoustically suited to reproducing lower midrange and upper bass frequencies, typically covering a range from approximately 60 Hz to 5 kHz depending on crossover configuration and driver characteristics.
- A midbass driver is a speaker type designed to handle the frequency band between bass and midrange, typically prioritizing cone excursion and low-distortion output in the 80 Hz to 500 Hz region rather than high-frequency extension.
- In a rear door panel position, a midbass type at 6.5 inches is suited to reinforcing the lower frequency content of the listening space, as the rear doors are physically distanced from the primary listening position and contribute spatial depth to low-midrange reproduction.
- A full-range driver is a speaker type designed to reproduce a wide frequency band from bass through treble within a single driver, relying on cone breakup or whizzer cone technology to extend upper-frequency response.
- When a full-range type is used in a rear door panel location, the 6.5 inch cone handles both low and high frequency content simultaneously, which places the driver in a position where the rear door cavity can introduce coloration at higher frequencies due to acoustic reflections within the door structure.
- The Mercedes-Benz CLS400 rear door panel accommodates the 6.5 inch format across the 2015, 2016, and 2017 model years, indicating a consistent mounting aperture and depth clearance across those vehicles.
