Mercedes-Benz GLK350 Rear Door Panel Speaker Size
The Mercedes-Benz GLK350 rear door panel accommodates a 6.5 inch speaker size and 1 inch speakers. Compatible types across these locations include midbass, full-range, and tweeter units. The specifications cover the 2010 to 2015 model years.
| 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 |
| 2012 | Tweeter | 1 |
| 2011 | Midbass / Full-Range | 6.5 |
| 2011 | Tweeter | 1 |
| 2010 | Midbass / Full-Range | 6.5 |
| 2010 | 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 in the Mercedes-Benz GLK350 places speakers within the door's inner structure, where the speaker faces inward toward the cabin and mounts against a flat or contoured surface within the door skin assembly.
- Door panel mounting positions the speaker driver at or near knee-to-hip height relative to seated passengers, which affects the angle and distance of sound projection toward the listening area in the rear seating row.
- A 6.5 inch driver in a door panel location has sufficient cone surface area to move the air volume needed to reproduce bass and lower midrange frequencies, typically covering a range from approximately 50 Hz to 5 kHz depending on driver construction.
- The physical depth of a 6.5 inch driver is a relevant factor in door panel installations, where the available cavity behind the mounting surface determines whether the driver's magnet assembly and basket will clear interior door components and window mechanisms.
- In the rear door panel position of the GLK350, a 6.5 inch midbass driver handles the lower portion of the frequency spectrum, generally from around 50 Hz to 500-800 Hz, reinforcing warmth, weight, and punch in the rear cabin zone.
- A 6.5 inch full-range driver in the same rear door panel location is designed to reproduce a wider frequency band without relying on a separate high-frequency driver, covering bass through upper midrange within a single transducer.
- The 2010, 2011, and 2012 model years of the Mercedes-Benz GLK350 rear door panel list a 1 inch tweeter position alongside the 6.5 inch driver, indicating a two-driver mounting arrangement within the same door panel.
- A 1 inch tweeter operates at high frequencies, typically from around 2 kHz to 20 kHz, where short wavelengths require a small, stiff diaphragm to reproduce transients and upper harmonics without significant distortion.
- The small diameter of a 1 inch tweeter results in a relatively narrow, directional dispersion pattern at the highest frequencies, meaning the mounting angle within the door panel influences how upper frequency content reaches rear passengers.
- The rear door panel position places the 1 inch tweeter at a lower height relative to ear level for a seated rear passenger, which differs from the near-ear positioning typical of A-pillar or sail panel tweeter locations.
- In a two-driver door panel configuration, the 6.5 inch driver and the 1 inch tweeter divide the frequency workload, with the crossover point between midbass and tweeter typically falling in the 2 kHz to 4 kHz range where the ear is highly sensitive to directional cues.
- The 2013, 2014, and 2015 model year rear door panel specifications list only a 6.5 inch driver, with no secondary driver position of a different size noted in the available data for those years.
