Mercedes-Benz CLS63 AMG Rear Door Panel Speaker Size
The Mercedes-Benz CLS63 AMG rear door panel accommodates a 6.5 inch speaker size across all listed model years. Compatible speaker types for the rear door panel audio system include midbass and full-range replacement units. These specifications cover the 2007 to 2015 model year chart range.
| Year | Type | Size (inch) |
|---|---|---|
| 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 in the Mercedes-Benz CLS63 AMG accommodates a 6.5 inch speaker opening across all listed model years from 2007 through 2015.
- Rear door panels typically position speakers low within the door cavity, mounting against an internal baffle surface with the cone facing into the cabin at an angle directed toward the passenger seating area.
- A 6.5 inch driver occupies a middle ground in cone surface area, producing sufficient cone excursion to move air efficiently within the enclosed door cavity, which functions as a partial acoustic chamber behind the mounting surface.
- The door panel enclosure in a rear door is shallower and more irregular than a dedicated speaker box, meaning cone depth and magnet clearance are relevant physical constraints for any driver installed in the Mercedes-Benz CLS63 AMG rear door panel location.
- A 6.5 inch diameter is well suited to reproducing frequencies in the midbass range, roughly from around 60 Hz to 500 Hz, where low-to-mid frequency content such as bass fundamentals and lower vocal harmonics are reproduced.
- Midbass drivers are optimized for the lower portion of the midrange and upper bass frequencies, using a stiffer cone suspension and moderate excursion characteristics to maintain accuracy under higher power demands without distortion in the bass region.
- Full-range drivers cover a wider frequency band than dedicated midbass units, typically from around 60 Hz up to 20 kHz, using either a single cone with a whizzer cone or a coaxial configuration to reproduce both low-mid and high-frequency content from a single mounting point.
- In a rear door panel location, a full-range driver can serve as a standalone speaker without requiring a separate tweeter in the same door, as the driver handles high-frequency reproduction internally.
- The rear door panel placement positions the speaker behind and to the side of rear-seat passengers, which affects the directional character of high-frequency content, since treble frequencies are more directional than bass frequencies and may require toe-in adjustment or rely on cabin reflections to reach listeners evenly.
- The cone area of a 6.5 inch driver is sufficient to reproduce midbass frequencies at moderate to high volume levels without requiring excessive excursion, which is relevant given the limited rear enclosure depth typical of door panel cavities.
