Mercedes-Benz C250 Rear Deck Center Speaker Size
The Mercedes-Benz C250 rear deck center location accommodates an 8 inch speaker size and 1 inch speakers. Compatible types for the audio system include subwoofer and tweeter replacement units. The specifications cover a range of years from 2012 to 2014.
| Year | Type | Size (inch) |
|---|---|---|
| 2014 | Subwoofer | 8 |
| 2014 | Tweeter | 1 |
| 2013 | Subwoofer | 8 |
| 2013 | Tweeter | 1 |
| 2012 | Subwoofer | 8 |
| 2012 | 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. |
| Subwoofer | A large driver for the lowest bass notes, typically from about 20 Hz to 120 Hz. It is usually installed in a separate enclosure and works alongside the other speakers. |
Additional Notes
- The rear deck center location in the Mercedes-Benz C250 accommodates 2 distinct speaker sizes simultaneously, indicating a multi-driver mounting configuration within a single installation zone.
- The rear deck is a horizontal surface positioned at the base of the rear window, behind the rear passenger seats, placing speakers in a rearward-facing or upward-radiating orientation relative to the cabin.
- An 8-inch subwoofer mounted at the rear deck center radiates low-frequency energy - typically below 200 Hz - upward and rearward into the cabin, where the rear shelf surface and rear window glass act as acoustic boundaries that influence bass distribution throughout the passenger compartment.
- The rear deck center position is a common subwoofer location because low-frequency wavelengths are long enough to appear omnidirectional to listeners in the front and rear seating areas, making precise placement less critical than with mid-range or high-frequency drivers.
- The Mercedes-Benz C250 rear deck center mounting for an 8-inch subwoofer requires a cutout and depth clearance sufficient for a driver of that cone diameter, with trunk space below the deck surface directly affecting available mounting depth.
- A 1-inch tweeter occupying the same rear deck center location handles high-frequency content, generally from around 2,000 Hz upward, where wavelengths are short and highly directional.
- The upward-firing orientation of a rear deck-mounted 1-inch tweeter disperses high-frequency content toward the headliner and rear window, which can cause reflected treble energy to reach front passengers indirectly rather than through direct radiation.
- Tweeters at 1 inch in diameter are physically compact, and co-locating one with an 8-inch subwoofer in the rear deck center requires either a dual-driver enclosure or separate mounting provisions within the same general deck opening area.
- The 8-inch and 1-inch driver pairing spans a wide frequency range between the two units, with a crossover point determining which frequencies are handled by each driver at this location.
- The specifications apply consistently across the 2012, 2013, and 2014 model years, indicating the rear deck center mounting dimensions and speaker configurations remained unchanged across those production years of the C250.
