Mercedes-Benz E350 Rear Deck Lid Speaker Size
The Mercedes-Benz E350 rear deck lid accommodates a 2.75 inch speaker size and 1 inch speakers, with each location supporting audio units of those respective sizes. Compatible speaker types across all years include midrange and tweeter. The specifications cover a range of years from 2007 to 2014.
| Year | Type | Size (inch) |
|---|---|---|
| 2014 | Midrange | 2.75 |
| 2013 | Midrange | 2.75 |
| 2012 | Midrange | 2.75 |
| 2011 | Midrange | 2.75 |
| 2010 | Midrange | 2.75 |
| 2009 | Tweeter | 1 |
| 2008 | Tweeter | 1 |
| 2007 | 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. |
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
Additional Notes
- The rear deck lid of the Mercedes-Benz E350 is a surface-mounted location positioned along the rear shelf of the cabin, behind the rear seating and below the rear window, placing speakers in a rearward-facing or upward-facing orientation relative to the passenger compartment.
- Deck lid installations are typically shallow-depth locations with limited enclosure volume and restricted mounting depth, which makes driver diameter and frame clearance critical factors in fitment.
- A 2.75 inch speaker in the rear deck lid position operates within the midrange frequency band, generally covering approximately 500 Hz to 5 kHz, which corresponds to the presence region of vocals, instruments, and upper harmonics in audio reproduction.
- At 2.75 inches, the cone area is small relative to full-range drivers, making the driver well-suited for midrange duties in the rear deck lid where spatial constraints limit larger installations.
- Midrange drivers in a rear deck lid location contribute directional fill toward the rear of the cabin, reinforcing the sense of spatial width and depth in the overall soundstage.
- A 1 inch tweeter handles high-frequency content, typically from around 2 kHz to 20 kHz, and in the Mercedes-Benz E350 rear deck lid, the placement positions high-frequency dispersion toward the rear passenger area and upward into the cabin.
- Tweeters at 1 inch have very light diaphragm mass, allowing fast transient response at high frequencies such as cymbals, string overtones, and vocal sibilance, which are the frequency components a tweeter at this location would reproduce.
- The 1 inch tweeter diameter requires minimal mounting depth and cutout area, making the rear deck lid a mechanically compatible location given the typically thin panel construction in that area of the E350.
- The rear deck lid location is structurally part of the trunk lid on sedan body styles, meaning the mounting surface is subject to vibration and mechanical resonance from road and engine sources, which can affect acoustic performance of any driver installed there.
- Midrange drivers at 2.75 inches lack low-frequency extension and are not designed to reproduce bass, so rear deck lid installations using this size rely on separate subwoofer or woofer components elsewhere in the system for low-end coverage.
- The transition between the 1 inch tweeter years and the 2.75 inch midrange years in the E350 rear deck lid reflects a change in the intended frequency role assigned to that specific location across the model's production span.
