Mercedes-Benz C320 Rear Side Panel Speaker Size
The Mercedes-Benz C320 rear side panel location accommodates a 3.5 inch speaker size and 6.5 inch speakers, reflecting 2 unique sizes across the model range. Compatible audio types include midrange and midbass / full-range units, depending on the applicable year. These specifications cover a system of model years ranging from 2003 to 2005.
| Year | Type | Size (inch) |
|---|---|---|
| 2005 | Midrange | 3.5 |
| 2004 | Midbass / Full-Range | 6.5 |
| 2003 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
| 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 side panel location in the Mercedes-Benz C320 accommodates 2 distinct speaker sizes across the model years covered in the specifications: 3.5 inch and 6.5 inch.
- A 3.5 inch driver in a rear side panel position handles midrange frequencies, typically spanning roughly 500 Hz to 5 kHz, where vocal clarity and instrument presence are concentrated.
- The 3.5 inch midrange driver's compact diameter limits low-frequency excursion, making the rear side panel in the 2005 Mercedes-Benz C320 dependent on additional bass support from other speaker positions in the system.
- A 6.5 inch driver carries enough cone surface area to move air at lower frequencies, which is why the rear side panel in the 2003 and 2004 C320 models supports midbass and full-range designations.
- Midbass drivers in a rear side panel location reinforce the lower midrange and upper bass frequencies, generally from around 80 Hz to 500 Hz, contributing body and warmth to the rear soundstage.
- Full-range drivers assigned to the 6.5 inch rear side panel position are designed to reproduce a broad frequency span without requiring a crossover network, relying on the driver's cone and surround to manage both low and high frequency content simultaneously.
- The rear side panel mounting position places speakers within the door or quarter panel structure behind the passenger seating area, which affects the directional projection of sound toward the cabin interior.
- Side panel mounting at the rear of the cabin means audio output from the driver is angled laterally rather than facing directly forward, influencing how reflected and direct sound energy reaches front and rear seat occupants.
- The enclosure characteristics of a rear side panel cavity, including the volume and rigidity of the surrounding panel material, directly affect the low-frequency extension and resonance behavior of whichever driver is installed.
- The shift from a 6.5 inch to a 3.5 inch driver between the 2004 and 2005 model years represents a significant reduction in cone surface area, which affects the rear side panel's capacity to reproduce lower frequencies at the same output level.
