Mercedes-Benz SLS AMG Rear Door Panel Speaker Size
The Mercedes-Benz SLS AMG rear door panel accommodates a 3.5 inch speaker size and 6.5 inch speakers, with each location supporting its respective size across different model years. Compatible speaker types for these units include midrange, midbass, and full-range audio configurations within the system. These specifications cover the 2011 to 2015 model year replacement chart range.
| Year | Type | Size (inch) |
|---|---|---|
| 2015 | Midrange | 3.5 |
| 2014 | Midrange | 3.5 |
| 2013 | Midbass / Full-Range | 6.5 |
| 2012 | Midrange | 3.5 |
| 2011 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
| 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 SLS AMG accommodates 2 distinct speaker sizes across the model years covered in the specifications: 3.5 inch and 6.5 inch.
- Door panel speaker locations are typically recessed within a cavity behind a grille or trim panel, with mounting depth and baffle diameter constrained by the door's internal structural frame and window mechanism clearances.
- The 3.5 inch diameter specified for the 2012, 2014, and 2015 model years indicates a relatively compact mounting footprint, which corresponds to a shallower rear mounting depth requirement and reduced magnet assembly clearance needed behind the door panel surface.
- A 3.5 inch speaker in a rear door panel position operates most effectively across the midrange frequency band, approximately 500 Hz to 5,000 Hz, where human vocal presence and instrument body tones are concentrated.
- The midrange type compatible with the 3.5 inch size in the SLS AMG rear door panel is a driver designed specifically for that 500 Hz to 5,000 Hz band, typically using a cone or dome diaphragm optimized for low distortion at conversational and instrumental frequencies rather than extended low-frequency excursion.
- The 6.5 inch diameter specified for the 2011 and 2013 model years requires a wider mounting cutout and generally a deeper rear cavity to accommodate the larger magnet structure, meaning the rear door panel in those years houses a physically larger speaker aperture.
- A 6.5 inch driver in a rear door panel position produces meaningful acoustic output in the lower midrange and upper bass frequencies, roughly 60 Hz to 4,000 Hz, due to the larger cone surface area generating greater air displacement at lower frequencies.
- The midbass type compatible with the 6.5 inch size in the Mercedes-Benz SLS AMG rear door panel is a driver engineered to handle the crossover region between subwoofer-range bass and midrange frequencies, typically covering 80 Hz to 500 Hz with controlled cone movement and a suspension tuned for moderate excursion.
- The full-range type also listed as compatible with the 6.5 inch size is a single driver designed to reproduce a wide frequency span without requiring a dedicated crossover network, using cone geometry and surround compliance that balance low-frequency extension against high-frequency dispersion in a single mounting location.
- Rear door panel placement positions the speaker at a lower height relative to the listening position, which affects the directional arrival angle of midrange and upper-frequency content at the occupant's ears, particularly relevant for the 3.5 inch midrange driver given the directional nature of higher-frequency sound waves.
- The difference in mounting cutout size between the 3.5 inch and 6.5 inch specifications means the two configurations are not interchangeable within the same rear door panel aperture without modification to the mounting surface.
