Mercedes-Benz R320 Cargo Area Speaker Size
The Mercedes-Benz R320 cargo area accommodates a 6.5 inch speaker size across all listed model years. Compatible audio types for the location include midbass and full-range system units. The specifications cover a range of years from 2007 to 2009.
| Year | Type | Size (inch) |
|---|---|---|
| 2009 | Midbass / Full-Range | 6.5 |
| 2008 | Midbass / Full-Range | 6.5 |
| 2007 | 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 cargo area of the Mercedes-Benz R320 accepts a 6.5-inch speaker mounting configuration across the 2007, 2008, and 2009 model years.
- A 6.5-inch driver occupies a mid-sized cone diameter, producing sufficient cone surface area to move air effectively in the lower-midrange and upper-bass frequencies, typically covering roughly 60 Hz to 5 kHz depending on driver construction.
- The cargo area placement positions speakers toward the rear of the vehicle cabin, a location acoustically removed from the primary listening position at the front seats, which affects soundstage depth and rear-fill contribution.
- Rear cargo area enclosures in wagon or van-style vehicles tend to have variable acoustic loading conditions due to cargo presence or absence altering the reflective surfaces around the speaker.
- A midbass driver in the cargo area location handles frequencies in the upper bass and lower midrange band, generally from approximately 80 Hz to 500 Hz, reinforcing low-frequency energy that travels well over distance toward front passengers.
- A full-range driver reproduces a wider frequency spectrum from a single cone, covering bass, midrange, and partial treble frequencies, making the cargo area location functional without requiring a separate tweeter in the same mounting position.
- The 6.5-inch format is a standard aftermarket size, and the Mercedes-Benz R320 cargo area compatibility with midbass and full-range types indicates the mounting depth and baffle cutout dimensions accommodate both driver categories at that diameter.
- Cargo area speakers in rear-positioned locations often operate with less high-frequency directional precision toward front occupants, since high-frequency sound is more directional and loses energy over longer distances, which is a factor relevant to choosing between midbass and full-range types at this location.
- A midbass driver, by design, rolls off high-frequency output and does not attempt to reproduce treble, which reduces the acoustic consequences of rear-firing or off-axis high-frequency dispersion at the cargo area position.
