Mercedes-Benz CLA45 AMG Rear Door Panel Speaker Size
The Mercedes-Benz CLA45 AMG rear door panel accommodates a 6.5 inch speaker size. Compatible types for the location include midbass and full-range audio units. These specifications cover the 2014 to 2017 model range.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Midbass / Full-Range | 6.5 |
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | 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 in the Mercedes-Benz CLA45 AMG places speakers within the lower portion of the door cavity, a position that typically couples bass energy into the cabin through the door's interior surface and surrounding panel structure.
- Door panel installations at the rear seat position are generally angled toward the passenger cabin floor area rather than directly at ear level, which influences how sound disperses throughout the cabin at listening height.
- The 6.5-inch diameter specified across all listed model years for the rear door panel location is a size that produces sufficient cone area to move air effectively in the low-to-mid frequency range, typically covering approximately 50 Hz to 5 kHz depending on driver construction.
- A 6.5-inch driver mounted in a door panel operates within a partially sealed or semi-open baffle formed by the door cavity itself, which affects the low-frequency extension and overall bass output the driver can achieve in the vehicle.
- The midbass type compatible with the Mercedes-Benz CLA45 AMG rear door panel is a driver optimized for frequencies roughly between 80 Hz and 500 Hz, prioritizing cone excursion and power handling over high-frequency extension.
- Midbass drivers in a rear door panel position reinforce the lower midrange and upper bass frequencies that contribute to perceived warmth and body in music reproduction within the cabin.
- The full-range type listed as compatible for the rear door panel is designed to reproduce a wider frequency span independently, covering bass, midrange, and portions of the high-frequency spectrum from a single driver without requiring a dedicated tweeter at that location.
- A 6.5-inch full-range driver in the rear door panel position must balance cone mass and stiffness to maintain useful output across a wide frequency band, which represents a different mechanical design priority compared to a dedicated midbass driver of the same size.
- The rear door panel location subjects mounted speakers to environmental factors including door slam vibration, moisture intrusion, and temperature fluctuation, all of which are relevant to the mechanical durability requirements of any driver installed at the 6.5-inch cutout.
- The door panel baffle depth and available mounting depth within the rear door of the CLA45 AMG determine whether a given 6.5-inch driver's magnet assembly and basket can be physically accommodated without contacting the door's inner metal skin.
