Mercedes-Benz CLA250 Rear Door Panel Speaker Size
The Mercedes-Benz CLA250 rear door panel accommodates a 6.5 inch speaker size across all listed model years. Compatible types for the audio system include midbass and full-range replacement units. These specifications cover a range of years from 2014 to 2017.
| 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 on the Mercedes-Benz CLA250 accommodates speakers mounted within the door's inner cavity, where the panel surface and available depth are defined by the door's structural geometry.
- Door panel installations are subject to spatial constraints from window mechanisms, door hardware, and internal bracing, all of which affect the usable mounting depth behind the speaker basket.
- A 6.5-inch speaker diameter refers to the nominal cone size, which determines the mounting cutout diameter and the bolt-hole pattern required to seat the driver securely within the door panel opening.
- The 6.5-inch cone area in a rear door panel location produces enough cone displacement to move air efficiently in a semi-enclosed cavity, supporting low-to-mid frequency reproduction in that acoustic environment.
- The rear door panel is an interior boundary surface, meaning bass frequencies produced by a 6.5-inch driver at this location benefit from some acoustic reinforcement from the door cavity acting as a partial enclosure behind the cone.
- Midbass drivers in the 6.5-inch format are designed to operate within approximately 80 Hz to 500 Hz, handling the lower midrange and upper bass frequencies that contribute to body and warmth in a vehicle's sound field.
- A midbass driver in the rear door panel position reinforces the low-frequency foundation of the stereo image from behind the listening position, complementing front-stage drivers.
- Full-range drivers cover a broader frequency span than dedicated midbass units, typically extending from around 60 Hz up to 20 kHz, functioning as a single driver responsible for the entire audible spectrum at the rear door location.
- The Mercedes-Benz CLA250 rear door panel across the 2014, 2015, and 2017 model years shares the same 6.5-inch mounting specification, indicating consistent door panel architecture across those model years.
- Door panel speakers at the rear position are generally mounted to radiate sound toward the vehicle interior at an angle determined by the door panel's inward-facing surface geometry, influencing the dispersion pattern reaching rear and front occupants.
- Full-range drivers in a rear door application must handle both bass and treble simultaneously without crossover support, which places broader demands on the driver's cone material, surround compliance, and voice coil design.
