Mercedes-Benz G550 Rear Door Panel Speaker Size
The Mercedes-Benz G550 rear door panel accommodates a 6.5 inch speaker size across all listed model years. Compatible speaker types for the audio system include midbass and full-range replacement units. These specifications cover the 2009 to 2017 model year chart range.
| Year | Type | Size (inch) |
|---|---|---|
| 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 |
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 G550 positions speakers within the interior door cavity, where the speaker baffle is integrated into the door panel structure and the speaker fires inward toward the cabin occupants.
- Door panel installations typically place the speaker cone in a vertical or near-vertical orientation, with the mounting surface flush against or recessed into the panel material.
- A 6.5 inch driver in a rear door panel location occupies a mid-sized footprint that fits within standard door cavity cutout dimensions common to full-size SUV platforms.
- The 6.5 inch cone diameter produces a diaphragm surface area suited to reproducing the lower-midrange and upper-bass frequency bands, generally spanning from approximately 60 Hz to 5 kHz depending on cone material and motor design.
- In a rear door panel position, a 6.5 inch driver benefits from the partial acoustic enclosure formed by the door cavity behind the speaker, which can reinforce low-frequency output without a dedicated sealed or ported enclosure.
- The midbass type is designed to handle frequencies in the lower-midrange and bass transition region, typically between roughly 80 Hz and 500 Hz, and is intended to work in conjunction with a separate tweeter or dedicated high-frequency driver in a component system.
- A midbass driver installed in the rear door panel of the Mercedes-Benz G550 focuses energy in the frequency range where male vocals, lower instrument fundamentals, and kick drum body are reproduced.
- The full-range type is designed to reproduce a wider span of the audible frequency spectrum from a single driver, commonly covering bass through treble frequencies without requiring a crossover-separated companion driver.
- A full-range 6.5 inch driver in the rear door panel location handles the entire audio signal passed to the rear channel, making tonal balance dependent on the driver's frequency response curve rather than an external crossover network.
- The rear door panel location places the speaker at ear level or below for seated rear passengers, which affects the perceived directionality and imaging of frequencies above approximately 1 kHz, where sound becomes increasingly directional.
- The G550's body-on-frame construction and substantial door mass may influence the acoustic coupling between the speaker and the door cavity, affecting resonance behavior across the reproduced frequency range.
