Mercedes-Benz GLK250 Rear Door Panel Speaker Size
The Mercedes-Benz GLK250 rear door panel accommodates a 6.5 inch speaker size across all listed model years. Compatible speaker types for the location include midbass and full-range audio units. The specifications cover a range of years from 2013 to 2015.
| Year | Type | Size (inch) |
|---|---|---|
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | Midbass / Full-Range | 6.5 |
| 2013 | 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 on the Mercedes-Benz GLK250 accommodates a 6.5 inch speaker across the 2013, 2014, and 2015 model years.
- Door panel speaker positions are typically recessed within a molded cavity in the door's inner skin, with mounting depth and baffle diameter constrained by the door's internal architecture and window mechanism hardware.
- A 6.5 inch cone diameter produces a relatively large radiating surface area, which supports the movement of air volumes necessary for reproducing lower-frequency content within the rear door environment.
- The rear door panel placement positions the speaker low in the cabin and toward the sides, a geometry that influences the directional behavior of mid and upper frequencies while lower frequencies remain largely omnidirectional.
- A midbass driver is designed to reproduce frequencies in the range roughly between 80 Hz and 500 Hz, covering the lower-midrange and upper-bass regions without extending into the full upper-midrange or treble bands.
- In a rear door panel location, a midbass driver operating in the 6.5 inch format reinforces the lower-frequency foundation of the soundstage, a role suited to the physical distance rear doors place between the driver and the listening position.
- A full-range driver is designed to reproduce a wide band of frequencies, typically from the lower bass region through the upper treble, without requiring a dedicated crossover network to limit bandwidth.
- When a 6.5 inch full-range driver is installed in the rear door panel of the Mercedes-Benz GLK250, the cone must handle both low-frequency excursion demands and the directional dispersion requirements of higher frequencies simultaneously.
- The rear door panel location subjects mounted speakers to road vibration, door slam resonance, and potential moisture intrusion, all of which are mechanical stressors inherent to door-mounted installations.
- The 6.5 inch mounting footprint requires a specific cutout diameter and bolt pattern in the door panel, and the Mercedes-Benz GLK250 rear door is specified to accommodate exactly 6.5 inch diameter units in the compatible types listed.
