Mercedes-Benz CLS550 Rear Door Panel Speaker Size
The Mercedes-Benz CLS550 rear door panel accommodates a 6.5 inch speaker size. Compatible speaker types for the location include midbass and full-range units. The specifications cover the years 2007 through 2017.

|---|---|---|
| 2017 | Midbass / Full-Range | 6.5 |
| 2016 | Midbass / Full-Range | 6.5 |
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | Midbass / Full-Range | 6.5 |
| 2013 | Midbass / Full-Range | 6.5 |
| 2012 | Midbass / Full-Range | 6.5 |
| 2011 | Midbass / Full-Range | 6.5 |
| 2010 | Midbass / Full-Range | 6.5 |
| 2009 | Midbass / Full-Range | 6.5 |
| 2008 | Midbass / Full-Range | 6.5 |
| 2007 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| Midbass | A driver tuned for upper bass and lower midrange, roughly from 80 Hz to 500 Hz. It has longer cone travel than a full-range unit, which supports stronger bass in doors and panels. |
| Full-Range | A single driver that reproduces bass through treble without a separate crossover network. It is the simplest replacement option and is common in factory audio systems. |
Additional Notes
- The rear door panel location on the Mercedes-Benz CLS550 positions speakers within the lower interior door cavity, where the driver is typically mounted facing inward toward the cabin at an angle relative to the listening position.
- Door panel installations are subject to the structural geometry of the door cavity, which limits mounting depth and may introduce acoustic interaction with the internal door structure, weather barriers, and window mechanisms.
- The rear door panel placement situates speakers behind and to the side of rear passengers, meaning sound arrives at an indirect angle rather than from a forward-facing axis aligned with the listener's ears.
- A 6.5 inch driver is a mid-sized cone speaker with a cone area large enough to move sufficient air for lower midrange and upper bass reproduction, typically covering a frequency range from approximately 60 Hz to 5,000 Hz depending on driver construction.
- The 6.5 inch diameter suits rear door panel cavities well because the available mounting cutout in many mid-size and full-size sedan doors accommodates cone drivers in the 6 to 7 inch range without requiring structural modification.
- The midbass type is a driver optimized for the lower portion of the midrange and the upper bass frequencies, generally operating between approximately 80 Hz and 500 Hz, and is not designed to reproduce the full audible spectrum independently.
- In a rear door panel location, a midbass driver contributes low-frequency body and warmth to the rear soundstage, reinforcing the lower registers produced elsewhere in the system.
- The full-range type is a single driver designed to reproduce a broad portion of the audible spectrum, typically from around 60 Hz to 20,000 Hz, though high-frequency extension varies by cone and surround material.
- A full-range driver installed in the Mercedes-Benz CLS550 rear door panel can operate as a standalone speaker for the rear channel without requiring a separate tweeter, given the broader frequency coverage relative to a dedicated midbass unit.
- The rear door panel location, being set low and to the sides of the rear seating area, means high-frequency directional content from a full-range driver may not radiate as precisely toward rear passengers as a separately positioned tweeter would.
- At 6.5 inches, the cone mass and surface area influence the transient response of the driver, with larger cones generally exhibiting greater inertia that can affect how quickly the speaker responds to rapid changes in the audio signal at higher frequencies.
- Both midbass and full-range types at 6.5 inches are acoustically suited to a door panel environment where the enclosure formed by the door cavity can reinforce bass output, functioning similarly to an infinite baffle or sealed enclosure depending on door sealing.
