Mercedes-Benz C320 Rear Deck Center Speaker Size
The Mercedes-Benz C320 rear deck center location accommodates an 8 inch speaker size and 1 inch speakers. Compatible audio types for the location include subwoofer and tweeter system replacement units. The specifications cover a range of years from 2001 to 2005.
| Year | Type | Size (inch) |
|---|---|---|
| 2005 | Subwoofer | 8 |
| 2005 | Tweeter | 1 |
| 2004 | Subwoofer | 8 |
| 2003 | Subwoofer | 8 |
| 2002 | Subwoofer | 8 |
| 2001 | Subwoofer | 8 |
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. |
| Subwoofer | A large driver for the lowest bass notes, typically from about 20 Hz to 120 Hz. It is usually installed in a separate enclosure and works alongside the other speakers. |
Additional Notes
- The rear deck center is a horizontal surface positioned at the base of the rear windshield, spanning the width of the cabin behind the rear seating.
- Mounting at the rear deck center places a speaker within a semi-enclosed space between the trunk cavity below and the passenger cabin above, which influences low-frequency projection and bass resonance characteristics.
- An 8-inch driver in the rear deck center position occupies a relatively large mounting cutout, requiring sufficient cone surface area clearance and adequate depth within the deck structure to accommodate the basket and magnet assembly.
- The 8-inch diameter corresponds to a cone surface area suited for moving larger volumes of air, which is mechanically necessary for reproducing low-frequency content at usable output levels.
- A subwoofer at the rear deck center is designated for reproducing the lowest frequencies in an audio system, typically operating in the range below 80 to 120 Hz, where wavelengths are long enough that directionality is largely non-directional to the human ear.
- Placement of a subwoofer at the rear deck center takes advantage of cabin boundary reinforcement, as the rear deck sits near multiple surfaces - the rear shelf, side panels, and rear windshield - which can contribute to low-frequency pressure buildup.
- The Mercedes-Benz C320 rear deck center subwoofer position accepts an 8-inch driver across the 2001 through 2005 model years, indicating a consistent physical mounting cutout and depth clearance across that range.
- The 2005 model year rear deck center adds a 1-inch tweeter compatibility alongside the 8-inch subwoofer, representing a second distinct driver type at the same location.
- A 1-inch tweeter is a high-frequency transducer, typically operating from approximately 2,000 Hz up to 20,000 Hz, where wavelengths are short and sound becomes increasingly directional.
- The 1-inch dome or cone tweeter size is associated with compact mounting dimensions, requiring a relatively small cutout and shallow rear clearance compared to larger driver formats.
- Positioning a tweeter at the rear deck center places high-frequency output at the rear of the cabin, projecting sound forward toward seated occupants from behind, which affects the spatial imaging characteristics of the audio field in the listening area.
