Mercedes-Benz CLK320 Rear Side Panel Speaker Size
The Mercedes-Benz CLK320 rear side panel accommodates a 6.5 inch speaker size and 3.5 inch speakers across the model's production span. Compatible audio types for these units include midrange and midbass / full-range system configurations. These specifications cover the 2000 to 2005 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2005 | Midbass / Full-Range | 6.5 |
| 2004 | Midrange | 3.5 |
| 2003 | Midrange | 3.5 |
| 2002 | Midrange | 3.5 |
| 2001 | Midrange | 3.5 |
| 2000 | Midrange | 3.5 |
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 CLK320 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 operates within a constrained mounting depth and baffle area, physically limiting cone excursion and low-frequency output relative to larger formats.
- The 6.5 inch size, present in the 2005 model year, occupies a substantially larger mounting cutout diameter, requiring a rear side panel cavity with sufficient depth and surface area to accommodate the larger basket and magnet assembly.
- Midrange drivers, as specified for the 3.5 inch position across the 2000 through 2004 model years, are designed to reproduce the middle portion of the audible frequency spectrum, generally spanning approximately 300 Hz to 5,000 Hz, where vocal intelligibility and upper instrumental tones reside.
- In a rear side panel location, midrange output contributes to cabin fill and ambient soundstage width rather than directional imaging, since rear-mounted drivers typically reinforce rather than anchor the perceived stereo field.
- The midbass type, listed as compatible for the 2005 6.5 inch position, handles frequencies in the lower-midrange and upper-bass transition zone, roughly 80 Hz to 500 Hz, allowing a single driver to bridge bass fundamentals and lower vocal harmonics within the rear side panel enclosure.
- Full-range compatibility, also listed for the 2005 Mercedes-Benz CLK320 rear side panel, indicates the 6.5 inch driver in that location can be operated across a wider frequency band without requiring additional crossover filtering, relying on the cone and suspension geometry to manage both low and high frequencies simultaneously.
- The rear side panel mounting position typically places the speaker behind and beside the passenger seating area, meaning the driver radiates toward the cabin interior at an oblique angle rather than directly toward the listener's ear axis.
- A 3.5 inch midrange driver produces a relatively narrow low-frequency extension in the rear side panel, meaning bass reproduction in the 2000 through 2004 model years depends on supplemental drivers elsewhere in the vehicle system.
- The transition from 3.5 inch midrange to 6.5 inch midbass/full-range between model years reflects a change in the physical dimensions of the rear side panel speaker cavity, as the 2 sizes are not interchangeable without modification to the mounting structure.
