Mercedes-Benz GLK350 Front Door Panel Speaker Size
The Mercedes-Benz GLK350 front door panel accommodates a 1 inch speaker size and 6.5 inch speakers across all model years covered. Compatible types for the audio system include tweeters and midbass or full-range replacement units. These specifications cover a range from 2010 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 |
| 2012 | Tweeter | 1 |
| 2012 | Midbass / Full-Range | 6.5 |
| 2011 | Tweeter | 1 |
| 2011 | Midbass / Full-Range | 6.5 |
| 2010 | Tweeter | 1 |
| 2010 | 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 of the Mercedes-Benz GLK350 accommodates 2 distinct speaker sizes per door, with a 6.5 inch position and a 1 inch position operating simultaneously within the same mounting surface.
- A front door panel location places speakers within the lower-to-mid lateral field of the cabin, where the baffle area of the door structure serves as the mounting platform and acoustic boundary for each driver.
- The 6.5 inch diameter is a mid-sized format that generates sufficient cone area to move air efficiently in the lower-midrange and upper-bass frequency bands, which aligns with the midbass and full-range designations listed for the Mercedes-Benz GLK350 front door panel position.
- At 6.5 inches, the speaker's physical excursion capability allows reproduction of frequencies roughly between 50 Hz and 5,000 Hz, covering the midbass region where punch, warmth, and vocal body are predominantly felt in a vehicle cabin.
- The 1 inch diameter format is suited to high-frequency reproduction, typically operating above 2,000 Hz to 3,000 Hz, where wavelengths are short enough to be handled without significant distortion by a small diaphragm.
- Tweeters of 1 inch diameter exhibit wide horizontal dispersion at upper-mid frequencies and progressively narrowing dispersion at the highest audible frequencies, a behavior that is relevant to a door panel position angled toward the listening area.
- The front door panel mounting height places the 6.5 inch midbass driver near or below ear level for seated occupants, a geometry that affects perceived bass localization and stereo imaging within the cabin.
- A full-range designation for the 6.5 inch position indicates the driver is specified to handle the entire audible spectrum independently when used without a tweeter, though the specifications also list a separate 1 inch tweeter position on the same panel.
- The midbass designation for the 6.5 inch position describes a driver configured to reproduce low-midrange and upper-bass content specifically, typically crossed over at a defined frequency point rather than operating across the full spectrum.
- Door panel cavities introduce acoustic loading conditions behind the driver, where internal volume, panel resonance, and structural material all interact with the rear wave produced by the 6.5 inch cone during operation.
- The 1 inch tweeter mounted on the front door panel of the GLK350 is positioned to contribute high-frequency content from within the door's vertical plane, influencing the spatial character of treble frequencies heard at the front seating positions.
