Mercedes-Benz E350 Rear Speaker Size
The Mercedes-Benz E350 rear location accommodates an 8 inch speaker size across all listed model years. Compatible types for the rear audio system include subwoofer replacement units. These specifications cover a range of years from 2007 to 2009.
| Year | Type | Size (inch) |
|---|---|---|
| 2009 | Subwoofer | 8 |
| 2008 | Subwoofer | 8 |
| 2007 | Subwoofer | 8 |
Speaker Types
| Type | Description |
|---|---|
| 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 speaker location in the Mercedes-Benz E350 accommodates an 8-inch driver across the 2007, 2008, and 2009 model years.
- An 8-inch speaker occupies a moderate-to-large mounting footprint, requiring sufficient cone excursion depth and rear cavity space to function at rated output.
- The rear location in the Mercedes-Benz E350 is specified exclusively for subwoofer-type drivers, meaning no full-range or coaxial configurations are listed for this position.
- A subwoofer is a driver engineered to reproduce low-frequency content, typically operating within the 20 Hz to 200 Hz range, where wavelengths are long and require greater cone surface area and displacement.
- An 8-inch cone diameter produces a meaningful radiating surface area, allowing the driver to move adequate air volume to reproduce bass frequencies within an enclosed or ported rear cavity.
- Subwoofers at the rear of a cabin take acoustic advantage of the enclosed air space behind the rear seat or within a trunk enclosure, which reinforces low-frequency output through boundary loading effects.
- At low frequencies, subwoofers are largely non-directional, meaning the rear placement does not impose significant front-to-back imaging constraints on the bass content produced.
- The 8-inch form factor in a rear subwoofer application represents a balance between the physical mounting envelope available and the low-frequency displacement needed to pressurize the cabin volume.
