Mercedes-Benz C320 Front Door Panel Speaker Size
The Mercedes-Benz C320 front door panel accommodates a 1 inch speaker size and 6.5 inch speakers within the same location. Compatible audio types across all years include tweeters and midbass or full-range units. The specifications cover a range from 2001 to 2005.
| Year | Type | Size (inch) |
|---|---|---|
| 2005 | Tweeter | 1 |
| 2005 | Midbass / Full-Range | 6.5 |
| 2004 | Tweeter | 1 |
| 2004 | Midbass / Full-Range | 6.5 |
| 2003 | Tweeter | 1 |
| 2003 | Midbass / Full-Range | 6.5 |
| 2002 | Tweeter | 1 |
| 2002 | Midbass / Full-Range | 6.5 |
| 2001 | Tweeter | 1 |
| 2001 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| Tweeter | A small driver built for high frequencies, typically from about 2,000 Hz to 20,000 Hz. It adds treble detail and clarity and is usually mounted near ear level or aimed at the listener. |
| 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 front door panel location in the Mercedes-Benz C320 accommodates 2 distinct speaker sizes simultaneously, indicating a multi-driver configuration within the same mounting zone.
- Door panel installations position speakers within a cavity formed by the door's inner structure, where the panel surface and surrounding air volume directly influence low-frequency loading and mid-range projection toward the cabin.
- The 6.5 inch position in the front door panel of the Mercedes-Benz C320 sits within a baffle environment that supports the cone excursion and air displacement needed for midbass reproduction, as larger-diameter drivers require adequate panel real estate and depth clearance to operate effectively.
- A 6.5 inch driver produces wavelengths in the midbass and lower midrange spectrum, roughly 80 Hz to 500 Hz, where door-mounted placement benefits from boundary reinforcement provided by the door cavity behind the cone.
- The full-range type compatibility of the 6.5 inch position means the driver at this location can be tasked with reproducing frequencies well above the midbass range when no separate tweeter is used, extending coverage into the upper midrange.
- The midbass designation for the 6.5 inch position reflects a role focused on lower-frequency content, where the driver operates below a crossover point and hands off higher frequencies to a separate driver.
- The 1 inch position in the front door panel operates as a tweeter, a driver type designed to reproduce high frequencies, typically from around 2,000 Hz to 20,000 Hz, where small diaphragm size minimizes mass and enables rapid oscillation.
- Tweeter placement within the front door panel directs high-frequency content from a lower position compared to typical A-pillar or sail panel locations, which affects the vertical dispersion angle relative to seated occupant ear height.
- A 1 inch tweeter produces a relatively narrow high-frequency dispersion pattern, meaning the listening axis from the front door panel position is a factor in perceived stereo imaging for front-seat occupants.
- The coexistence of a 1 inch tweeter position and a 6.5 inch midbass/full-range position within the same front door panel indicates the mounting surface contains 2 separate cutouts or housings sized to each driver's diameter.
- Door panel thickness and inner door shell depth constrain the mounting depth available for both the 6.5 inch and 1 inch drivers, as each size carries different basket depth requirements that must be compatible with the door's internal clearance.
