Mercedes-Benz S350 Rear Door Panel Speaker Size
The Mercedes-Benz S350 rear door panel accommodates a 6.5 inch speaker size across all listed model years. Compatible types for the audio system include midbass and full-range replacement units. These specifications cover the 2006 to 2013 chart of model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2013 | Midbass / Full-Range | 6.5 |
| 2012 | Midbass / Full-Range | 6.5 |
| 2006 | 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 S350 positions speakers within the lower portion of the door cavity, a placement that couples speaker output with the door's internal volume and directs sound toward the vehicle's lower cabin space.
- Door panel installations typically involve mounting onto a baffle or bracket within the door skin, where the speaker faces inward toward the passenger compartment rather than in a free-air or sealed enclosure configuration.
- A 6.5-inch driver in a rear door panel application occupies a mid-sized footprint that fits within the structural constraints of a full-size luxury sedan door without requiring modification to the door's internal framing.
- The 6.5-inch cone diameter produces a surface area large enough to move sufficient air for reproducing the lower midrange and upper bass frequencies that smaller drivers cannot efficiently handle in a door-mounted position.
- In a rear door panel location, a 6.5-inch driver operates with some degree of acoustic loading provided by the door cavity itself, which can extend low-frequency output compared to an open-air installation.
- The midbass type is a driver optimized to reproduce frequencies roughly between 80 Hz and 500 Hz, a range that covers kick drum fundamentals, bass guitar body, and male vocal lower harmonics.
- A midbass driver in the rear door panel of the Mercedes-Benz S350 functions as part of a multi-driver system, handling the lower portion of the audible spectrum while higher frequencies are managed by separate drivers elsewhere in the cabin.
- The full-range type is a driver designed to reproduce a wider portion of the audible spectrum from bass through treble within a single cone, sometimes incorporating a whizzer cone or small internal tweeter to extend high-frequency response.
- A full-range driver installed in the rear door panel location handles the entirety of the frequency spectrum directed to that position, without requiring a separate crossover network to divide frequencies among multiple rear-door drivers.
- The rear door panel placement affects the stereo imaging characteristics of the cabin, as sound from a 6.5-inch driver at door height arrives at seated passengers from a low lateral angle rather than at ear level.
