Mercedes-Benz S320 Rear Deck Lid Speaker Size
The Mercedes-Benz S320 rear deck lid location 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 1994 to 1997 model year chart range.
| Year | Type | Size (inch) |
|---|---|---|
| 1997 | Midbass / Full-Range | 6.5 |
| 1996 | Midbass / Full-Range | 6.5 |
| 1995 | Midbass / Full-Range | 6.5 |
| 1994 | 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 deck lid location in the Mercedes-Benz S320 accommodates a 6.5 inch speaker cutout across all listed model years.
- A rear deck lid position places speakers in a horizontal, surface-mounted orientation at the rearmost section of the cabin, typically above the trunk cavity and below the rear window.
- Horizontal mounting at the rear deck lid directs acoustic output upward toward the cabin ceiling and rear windshield, which acts as a reflective surface that disperses sound toward front and rear passengers.
- The 6.5 inch diameter is a mid-size cone format that balances low-frequency extension with midrange clarity, handling roughly 60 Hz to 5,000 Hz depending on driver design and enclosure conditions.
- At the rear deck lid, the trunk cavity beneath the mounting surface can function as an informal acoustic chamber, influencing bass resonance and low-frequency output of a 6.5 inch driver.
- A midbass driver in the 6.5 inch format at a rear deck location is tuned primarily for frequencies in the 80 Hz to 500 Hz range, reinforcing the lower midrange and upper bass registers within the cabin.
- A full-range driver of the same 6.5 inch size covers a wider frequency band than a dedicated midbass unit, typically extending from around 60 Hz up to 20,000 Hz, though upper treble dispersion from a rear deck position is limited by the driver's off-axis angle relative to seated passengers.
- The Mercedes-Benz S320 rear deck lid accepts both midbass and full-range types within the same 6.5 inch mounting format, indicating a shared physical opening dimension for both driver categories across the 1994 to 1997 model range.
- Full-range drivers rely on cone geometry and sometimes a dust cap or whizzer cone to reproduce high frequencies, making rear deck placement acoustically less ideal for treble reproduction due to the rearward and upward dispersion angle relative to front-seat listeners.
- Midbass drivers at the rear deck lid position are commonly used in multi-amplified or component system configurations where a separate tweeter handles high frequencies from a more forward or elevated location in the cabin.
