Mercedes-Benz S55 AMG Rear Door Panel Speaker Size
The Mercedes-Benz S55 AMG rear door panel accommodates a 6.5 inch speaker size as well as 5.25 inch and 1 inch speakers across the model's production span. Compatible audio types include tweeters and midbass or full-range units. These specifications cover the 2001 to 2006 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2006 | Midbass / Full-Range | 6.5 |
| 2005 | Tweeter | 1 |
| 2005 | Midbass / Full-Range | 5.25 |
| 2004 | Tweeter | 1 |
| 2004 | Midbass / Full-Range | 5.25 |
| 2003 | Tweeter | 1 |
| 2003 | Midbass / Full-Range | 5.25 |
| 2002 | Tweeter | 1 |
| 2002 | Midbass / Full-Range | 5.25 |
| 2001 | Tweeter | 1 |
| 2001 | Midbass / Full-Range | 5.25 |
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. |
| 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 places speakers within the lower lateral sections of the cabin, mounting drivers at roughly seat-level height within the door structure.
- Door panel installations are subject to spatial constraints from the door's internal mechanical components, including window regulators and locking hardware, which influence the depth and diameter of speaker cutouts.
- The Mercedes-Benz S55 AMG rear door panel accommodates either a single driver or a 2-driver configuration depending on the model year, with 2001 through 2005 specifying both a 5.25 inch and a 1 inch position, while 2006 specifies a single 6.5 inch position.
- A 5.25 inch driver in a door panel location handles the midbass and midrange frequency bands, generally covering roughly 80 Hz to 5 kHz, which includes fundamental vocal frequencies and a significant portion of musical instrument harmonics at the rear seat listening position.
- The 6.5 inch driver specified for the 2006 model year is a larger cone format that extends lower into the bass region compared to 5.25 inch drivers, allowing the rear door panel in that year to reproduce more low-frequency content without a dedicated subwoofer in the same location.
- A full-range type designation for the 5.25 inch and 6.5 inch positions means a single driver is responsible for reproducing the entire audible spectrum assigned to the rear door, rather than relying on a crossover-divided multi-driver arrangement.
- A midbass type designation for the same 5.25 inch and 6.5 inch positions indicates use within a crossed-over system where the driver handles only lower-midrange and bass frequencies, with higher frequencies delegated to a separate tweeter.
- The 1 inch tweeter specified in the rear door panel for the 2001 through 2005 Mercedes-Benz S55 AMG rear door panel handles high-frequency content, typically from around 2 kHz upward, which includes consonant clarity, cymbal detail, and upper harmonic overtones.
- A 1 inch tweeter dome is physically small, allowing placement within the limited real estate of a door panel without requiring a large cutout, and the small diaphragm mass contributes to accurate transient response at high frequencies.
- Mounting a tweeter in the rear door panel positions high-frequency dispersion toward rear seat occupants laterally, which differs acoustically from dash or A-pillar tweeter placement that projects sound forward.
- The rear door panel location subjects drivers to vibrational energy from the door structure itself, road noise transmission through the door skin, and potential air pressure fluctuations from window operation, all of which are mechanical factors relevant to driver mounting rigidity.
