Mercedes-Benz GLC300 Rear Door Panel Speaker Size
The Mercedes-Benz GLC300 rear door panel accommodates a 6.5 inch speaker size across all listed model years. Compatible types for the location include midbass and full-range units. These specifications cover the 2016 to 2017 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Midbass / Full-Range | 6.5 |
| 2016 | 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 GLC300 accommodates a 6.5 inch speaker across the 2016 and 2017 model years.
- A 6.5 inch driver in a rear door panel position operates within a physical cavity bounded by the door's inner skin, outer skin, and panel trim, all of which affect the available mounting depth and baffle surface area.
- Door panel installations require attention to mounting depth clearance, as the window regulator mechanism and glass travel path within the door cavity can restrict how far a speaker basket extends inward.
- The 6.5 inch diameter gives a cone surface area suited to reproducing lower midrange and upper bass frequencies with meaningful excursion capability, placing most of the acoustic energy in the 60 Hz to 5 kHz range depending on driver design.
- A midbass driver in the rear door panel position is designed to handle frequencies from the upper bass range through the lower midrange, typically crossed over at both the low and high ends to work within a multi-speaker system where a subwoofer handles deep bass and a tweeter handles high frequencies.
- A full-range driver in the same rear door panel position covers a wider frequency span than a midbass unit, typically from around 60 Hz up to 20 kHz, making the Mercedes-Benz GLC300 rear door panel a viable location for single-driver operation without supplemental high-frequency components.
- The rear door panel position places the speaker at lower-body height relative to seated occupants, which affects the directional arrival angle of sound, particularly at higher frequencies where wavelengths are short enough to be directional.
- At 6.5 inches, the cone diameter produces wavelengths that begin to become directional above approximately 2 kHz, meaning the dispersion pattern narrows as frequency rises when a full-range driver handles the upper frequency range from the rear door position.
- Midbass drivers are typically built with stiffer suspensions and lower Xmax requirements than subwoofers, suited to the moderate excursion demands of the rear door panel's acoustic role in a full system configuration.
- The rear door panel location on the GLC300 spans both 2016 and 2017 model years with an identical 6.5 inch specification, indicating dimensional consistency in the speaker cutout and mounting ring geometry across those two production years.
