Mercedes-Benz GL350 Rear Door Panel Speaker Size
The Mercedes-Benz GL350 rear door panel accommodates a 6.5 inch speaker size and 1 inch speakers, covering all unique sizes found across the model range. Compatible speaker types for these locations include midbass, full-range, and tweeter units. These specifications cover the 2010 to 2016 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2016 | Midbass / Full-Range | 6.5 |
| 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 on the Mercedes-Benz GL350 accommodates speakers mounted within the structural cavities of the rear passenger doors, positioning drivers laterally within the cabin at roughly seat-level height.
- Door panel installations are subject to spatial constraints from the door's internal framework, window mechanisms, and wiring, which limits both the mounting depth and the diameter of compatible drivers.
- The 6.5 inch diameter is a mid-sized woofer format whose cone area is large enough to move sufficient air for lower midrange and upper bass frequencies, generally covering a range from approximately 60 Hz to 5 kHz depending on driver design and crossover configuration.
- Placed within the rear door panel, a 6.5 inch driver directs sound toward the cabin floor and rear passenger seating area, contributing to the lower portion of the frequency spectrum experienced by rear occupants.
- Midbass drivers within the 6.5 inch format are optimized for the frequency band between bass and midrange, typically 80 Hz to 500 Hz, and are designed to reproduce the foundational weight of instruments and vocals without extending into high-frequency reproduction.
- Full-range drivers in the 6.5 inch format are designed to reproduce a wider span of audible frequencies from a single cone, making one driver responsible for bass, midrange, and a limited degree of treble in the rear door location.
- The 1 inch format is a compact high-frequency driver whose small diaphragm mass allows rapid cone movement, enabling reproduction of frequencies generally from around 2 kHz up to 20 kHz.
- At 1 inch, a tweeter mounted in the rear door panel of the Mercedes-Benz GL350 introduces high-frequency content into the rear cabin zone, adding treble definition and air to the audio image experienced by rear passengers.
- Tweeters rely on their small diaphragm size to achieve controlled directional dispersion at high frequencies, meaning placement within the door panel influences the angle and breadth of treble projection toward rear seating positions.
- The presence of both a 6.5 inch driver and a 1 inch tweeter in the same rear door panel for the 2010, 2011, and 2012 model years indicates a multi-driver configuration at that location, where each driver handles a separate portion of the frequency range.
- In a multi-driver rear door setup, the 6.5 inch and 1 inch drivers operate in different acoustic roles simultaneously, with the larger driver covering low and mid frequencies while the smaller driver reproduces high-frequency content within the same physical panel.
- The rear door panel location introduces acoustic challenges such as panel resonance and reflections from interior surfaces, which interact with the output of both the 6.5 inch and 1 inch drivers mounted within.
