Mercedes-Benz S320 Rear Door Panel Speaker Size
The Mercedes-Benz S320 rear door panel accommodates a 5.25 inch speaker size across all listed model years. Compatible types for the location include midbass and full-range units. The specifications cover a range of 1998 to 1999.
| Year | Type | Size (inch) |
|---|---|---|
| 1999 | Midbass / Full-Range | 5.25 |
| 1998 | Midbass / Full-Range | 5.25 |
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 S320 accommodates a 5.25-inch speaker across both listed model years.
- Door panel mounting positions are typically recessed within a molded cavity, meaning speaker depth (mounting depth) and basket diameter must align with the available cutout and clearance behind the panel surface.
- Rear door panel installations place speakers within an enclosed or semi-enclosed cavity formed by the door's inner structure, which can affect low-frequency buildup and baffle resonance behavior.
- A 5.25-inch driver in a rear door panel position operates within a spatial enclosure that is shallower and more irregular than a dedicated speaker box, influencing the bass extension the driver can realistically reproduce.
- The 5.25-inch diameter places the cone surface area in a range suited to reproducing upper bass and midrange frequencies, generally covering approximately 80 Hz to 5,000 Hz depending on driver construction.
- Midbass drivers in the rear door panel position are designed to handle the lower portion of the midrange and upper bass frequencies, typically crossed over from a subwoofer below and a tweeter or midrange driver above.
- Full-range drivers covering the rear door panel position are constructed to reproduce a broader frequency spectrum without requiring additional crossover components, spanning bass through upper midrange from a single cone.
- In a rear door panel location, a midbass driver contributes directional low-mid energy toward the vehicle cabin, with dispersion characteristics that are relatively wide at lower frequencies and narrowing as frequency rises.
- The Mercedes-Benz S320 rear door panel's 5.25-inch cutout specification means full-range replacements must also conform to the same mounting diameter, ensuring cone and surround geometry fit within the existing opening.
- Full-range drivers at 5.25 inches in a rear door position tend to reproduce vocals and instrument body frequencies, as the cone diameter limits deep bass output while still handling midrange detail adequately.
