Mercedes-Benz GLK250 Front Door Panel Speaker Size
The Mercedes-Benz GLK250 front door panel accommodates a 1 inch speaker size and 6.5 inch speakers across all listed years. Compatible types for these locations include tweeters and midbass or full-range units. The specifications cover a range of years from 2013 to 2015.
| Year | Type | Size (inch) |
|---|---|---|
| 2015 | Tweeter | 1 |
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | Tweeter | 1 |
| 2014 | Midbass / Full-Range | 6.5 |
| 2013 | Tweeter | 1 |
| 2013 | Midbass / Full-Range | 6.5 |
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 front door panel location of the Mercedes-Benz GLK250 accommodates 2 distinct speaker sizes simultaneously, a 1-inch position and a 6.5-inch position, indicating a multi-driver configuration within the same door.
- Door panel installations mount speakers within an enclosed cavity, where the panel itself acts as a baffle, influencing low-frequency reinforcement and overall projection into the cabin.
- The 6.5-inch driver position in the GLK250 front door panel is sized to handle the lower portion of the audible spectrum, typically covering frequencies from around 50 Hz to 5 kHz, making effective use of the door's larger air volume and physical distance from the listener's ear.
- A 6.5-inch diameter cone has sufficient surface area to move the volume of air necessary for reproducing midbass frequencies with adequate output levels in an automotive cabin environment.
- The 1-inch driver position sits alongside the 6.5-inch position in the front door panel, placing high-frequency reproduction close to ear level when the door is closed, which aids in stereo imaging and soundstage width.
- A 1-inch tweeter operates in the upper frequency range, generally from around 2 kHz to 20 kHz, where short wavelengths require a small, lightweight diaphragm capable of rapid movement.
- Tweeters of 1-inch diameter are highly directional at upper frequencies, so placement within the front door panel of the GLK250 affects the angle at which high-frequency sound reaches the listening position.
- The midbass type compatible with the 6.5-inch position is a driver optimized for the frequency band between bass and midrange, typically crossing over from a subwoofer below and handing off to a tweeter above.
- The full-range type compatible with the 6.5-inch position is a single driver designed to reproduce a wider portion of the audible spectrum without requiring an external crossover, relying on the cone's physical properties to manage frequency rolloff.
- The front door panel location subjects speakers to mechanical vibration from road noise and door operation, as well as moisture exposure, both of which are factors in driver material and mounting hardware selection.
- The GLK250 front door panel specifications are consistent across the 2013, 2014, and 2015 model years, with both the 1-inch and 6.5-inch positions remaining unchanged throughout.
