Mercedes-Benz E63 AMG Rear Door Panel Speaker Size
The Mercedes-Benz E63 AMG rear door panel accommodates a 6.5 inch speaker size and also supports 1 inch units, covering all speaker positions within the location. Compatible types across these sizes include midbass, full-range, and tweeter audio system components. The specifications cover the 2007 to 2015 model 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 |
| 2009 | Tweeter | 1 |
| 2008 | Midbass / Full-Range | 6.5 |
| 2008 | Tweeter | 1 |
| 2007 | Midbass / Full-Range | 6.5 |
| 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. |
| 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 E63 AMG positions speakers within the lower portion of the door cavity, placing drivers closer to the floor level and angled generally toward the cabin interior.
- Door panel mounting in a rear door places speakers at a distance from the primary listening position in the front seats, which affects the time-arrival characteristics of sound reaching rear passengers versus front passengers.
- The 6.5 inch diameter is a mid-sized woofer format that, in a rear door panel cavity, draws on the door's internal air volume as a partial acoustic enclosure, influencing low-frequency extension and cone excursion behavior.
- A 6.5 inch driver reproduces frequencies roughly from the low bass region through the upper midrange, making the rear door panel a location suited to handling the majority of the audible spectrum when full-range operation is specified.
- When the 6.5 inch driver operates in midbass mode at the rear door panel, crossover filtering limits the driver to lower and mid frequencies, reducing stress on the cone and improving output clarity in the bass and lower midrange bands.
- The 1 inch tweeter listed for the Mercedes-Benz E63 AMG rear door panel in 2007, 2008, and 2009 occupies a separate mounting position within the same door panel, typically positioned higher or angled differently than the woofer to improve high-frequency dispersion.
- A 1 inch tweeter handles the upper portion of the audible frequency range, generally from around 2,000 Hz upward, where shorter wavelengths require a smaller diaphragm for accurate reproduction and controlled directional dispersion.
- The presence of a separate 1 inch tweeter alongside a 6.5 inch driver in the rear door panel indicates a 2-way speaker arrangement at that location, with each driver assigned a distinct frequency band.
- In a rear door panel, tweeter placement is significant because high frequencies are highly directional, and the mounting angle of the 1 inch unit relative to the rear seat occupants determines the perceived treble energy and stereo imaging at that seating position.
- The full-range designation for the 6.5 inch driver means a single driver at the rear door panel location is capable of handling the entire audible frequency spectrum without an accompanying tweeter, as reflected in the model years that list only the 6.5 inch entry.
- Door panel cavities in vehicles like the E63 AMG are not acoustically sealed enclosures, as door internals contain openings, bracing, and hardware that affect rear-wave behavior and bass response of the 6.5 inch driver mounted within.
- The spatial constraints of the rear door panel limit the mounting depth available for the 6.5 inch driver, making the mounting depth specification of any replacement driver a critical fitment consideration for the Mercedes-Benz E63 AMG rear door panel location.
