Mercedes-Benz R350 Cargo Area Speaker Size
The Mercedes-Benz R350 cargo area accommodates a 6.5 inch speaker size across all listed model years. Compatible speaker types for the audio system include midbass and full-range replacement units. These specifications cover the 2006 to 2010 model year chart range.
| Year | Type | Size (inch) |
|---|---|---|
| 2010 | Midbass / Full-Range | 6.5 |
| 2009 | Midbass / Full-Range | 6.5 |
| 2008 | Midbass / Full-Range | 6.5 |
| 2007 | 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 cargo area of the Mercedes-Benz R350 accommodates 6.5 inch speakers across the 2006 through 2010 model years.
- Cargo area speaker locations are typically mounted low and rearward in the vehicle cabin, positioned at or near floor level along the side panels or rear enclosure walls.
- A 6.5 inch driver occupies a mid-sized cone diameter that produces sufficient cone surface area to move air effectively in the lower-mid frequency region, generally covering approximately 80 Hz to 5 kHz depending on driver construction.
- The physical depth and diameter requirements of a 6.5 inch speaker in a cargo area mount demand adequate clearance behind the panel, as cargo zones often present shallow or irregular cavities behind trim surfaces.
- Mounting in the cargo area places the speaker at a significant distance from front-seat listening positions, which influences time alignment and the perceived directional quality of sound produced at that location.
- The midbass type is a driver optimized to reproduce the lower portion of the midrange and upper bass frequencies, typically spanning roughly 80 Hz to 500 Hz, with a cone and suspension tuned for controlled low-frequency excursion rather than high-frequency extension.
- In a cargo area position, a midbass driver reinforces foundational low-mid energy toward the rear of the cabin, where bass frequencies tend to build due to the enclosed nature of the space behind the rear seating.
- The full-range type is a single driver designed to reproduce a broad spectrum of frequencies, from bass through treble, often incorporating a passive radiator or whizzer cone to extend high-frequency response beyond what the main cone alone produces.
- A full-range driver installed in the Mercedes-Benz R350 cargo area at 6.5 inches covers a wider audible bandwidth from a single mounting point, which is acoustically relevant in a location where adding separate tweeters may not be feasible.
- The cargo area in a multi-row vehicle such as the R350 functions as an enclosed acoustic boundary at the terminus of the cabin, meaning low-frequency energy generated by drivers in this location can reflect and reinforce within the surrounding surfaces.
