Mercedes-Benz ML63 AMG Rear Door Panel Speaker Size
The Mercedes-Benz ML63 AMG rear door panel accommodates a 6.5 inch speaker size and supports 1 inch units. Compatible audio types for the location include midbass, full-range, and tweeter. These specifications cover a range of years from 2007 to 2015.

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 of the Mercedes-Benz ML63 AMG accommodates 2 distinct speaker sizes simultaneously: a 6.5 inch driver and a 1 inch driver, indicating a multi-driver configuration within the same panel location.
- Door panel installations are typically surface-mounted or recessed into a molded cavity within the door card, with the available depth and baffle area of the panel determining the maximum cone excursion and enclosure characteristics of any installed driver.
- The 6.5 inch diameter corresponds to a mid-sized woofer cone area capable of moving sufficient air to reproduce frequencies in the midbass range, generally from approximately 80 Hz up to 500 Hz, while also covering the midrange frequencies required of a full-range driver.
- In a rear door panel position, a 6.5 inch driver is physically distant from front-seat occupants, which affects the time-alignment and staging of frequencies in the midbass and midrange bands relative to forward-mounted speakers.
- The midbass type designation for the 6.5 inch position indicates a driver optimized for the lower portion of the midrange spectrum, with a stiffer suspension and controlled excursion suited to reinforcing low-mid frequencies without extending into full treble reproduction.
- The full-range type designation for the 6.5 inch position indicates a driver capable of reproducing a wider frequency band independently, from bass through treble, within the acoustic limitations of the door panel mounting environment.
- The 1 inch diameter of the tweeter position corresponds to a small, high-frequency driver with a lightweight diaphragm, typically reproducing frequencies from approximately 2 kHz upward, where short wavelengths require a small radiating surface for accurate dispersion.
- Tweeters mounted within a rear door panel radiate high-frequency energy into the rear passenger zone, where the directional and reflective behavior of 1 inch drivers at high frequencies is influenced by the surrounding door card material and panel geometry.
- The tweeter type is inherently a high-frequency-only driver and is not suited to reproduce the midbass or low-midrange content handled by the 6.5 inch driver in the same panel location.
- The rear door panel location places both drivers at a low height relative to seated passengers, which affects the vertical dispersion angle of high-frequency content produced by the 1 inch tweeter toward rear occupants.
- The consistent presence of both a 6.5 inch and a 1 inch fitment across all model years from 2007 through 2015 indicates that the rear door panel dimensions and mounting provisions remained unchanged across the entire listed production span of the ML63 AMG.
