Mercedes-Benz E350 Rear Roof Speaker Size
The Mercedes-Benz E350 rear roof location accommodates a 1 inch speaker size. Tweeter units are the compatible audio system replacement types available for the rear roof. These specifications cover the 2006 to 2009 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2009 | Tweeter | 1 |
| 2008 | Tweeter | 1 |
| 2007 | Tweeter | 1 |
| 2006 | Tweeter | 1 |
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. |
Additional Notes
- The rear roof location in the Mercedes-Benz E350 accommodates a 1-inch speaker opening across the 2006 through 2009 model years.
- A 1-inch diameter is a compact form factor that positions the driver close to the listener in a rear roof mounting point, which reduces the distance high-frequency sound must travel before diffusing into the cabin.
- The rear roof is an elevated, centrally positioned mounting location within the vehicle interior, placing speakers above and behind rear-seat occupants.
- Tweeters are the sole compatible type for the rear roof position in the Mercedes-Benz E350, meaning the location is designated exclusively for high-frequency reproduction rather than full-range or low-frequency output.
- Tweeters reproduce the upper portion of the audible frequency spectrum, generally from approximately 2,000 Hz to 20,000 Hz, covering sounds such as vocals, string harmonics, and transient audio detail.
- A 1-inch tweeter dome or cone has a small radiating surface area, which is acoustically suited to high-frequency reproduction because larger surfaces introduce unwanted resonance and directional inconsistency at upper frequencies.
- Mounting at the rear roof places the tweeter at a height elevation relative to the seat surface, which allows high-frequency dispersion to project downward and forward into the rear seating area.
- Tweeters have a relatively narrow dispersion pattern compared to woofers, and a ceiling-mounted position in the rear of the cabin allows the driver to direct high frequencies toward the listening zone without significant obstruction from seat structures or door panels.
- The 1-inch size constraint at the rear roof position limits the physical depth and basket diameter of any compatible tweeter, which is consistent with the shallow cavities typically found in roof headliner installations.
