Mercedes-Benz E320 Rear Deck Center Speaker Size
The Mercedes-Benz E320 rear deck center location accommodates 1 inch speakers and an 8 inch speaker size across all listed model years. Compatible types for the audio system include tweeters and subwoofers. The specifications cover a range of years from 2003 to 2006.
| Year | Type | Size (inch) |
|---|---|---|
| 2006 | Tweeter | 1 |
| 2006 | Subwoofer | 8 |
| 2005 | Tweeter | 1 |
| 2005 | Subwoofer | 8 |
| 2004 | Tweeter | 1 |
| 2004 | Subwoofer | 8 |
| 2003 | Tweeter | 1 |
| 2003 | 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 location in the Mercedes-Benz E320 accommodates 2 distinct speaker sizes: 1 inch and 8 inch.
- The rear deck is a horizontal surface positioned at the base of the rear windshield, behind the rear passenger seats, and above the trunk cavity.
- An 8-inch subwoofer mounted at the rear deck center takes advantage of the enclosed or semi-enclosed volume of the trunk space beneath, which acts as a natural acoustic chamber for low-frequency reinforcement.
- Subwoofers reproduce the lowest frequencies in an audio system, generally below 200 Hz, and the rear deck center position places the driver at a central lateral point, supporting even bass distribution across the cabin width.
- A 1-inch tweeter handles high-frequency content, typically above 2,000 Hz, where wavelengths are short enough that even small positional differences affect perceived directionality and imaging.
- The Mercedes-Benz E320 rear deck center mount for a 1-inch tweeter places high-frequency output at a central horizontal axis, which is a factor in stereo imaging symmetry for rear-cabin listeners.
- Tweeters of 1 inch in diameter have a small radiating surface, which corresponds to the reproduction of high-frequency sounds that require rapid, low-mass cone movement rather than large cone excursion.
- The coexistence of a 1-inch tweeter and an 8-inch subwoofer at the same rear deck center location indicates the presence of 2 separate speaker cutouts or mounting positions within that zone, each sized to its respective driver.
- An 8-inch subwoofer requires a larger cutout diameter and greater depth clearance than a 1-inch tweeter, making the structural depth and rigidity of the rear deck relevant to the physical fitment of the larger driver.
- The rear deck center position places both driver sizes along the vehicle's longitudinal centerline, which is a symmetrical axis relative to the left and right channels of the cabin interior.
