Mercedes-Benz CLK55 AMG Behind Rear Seat Speaker Size
The Mercedes-Benz CLK55 AMG behind rear seat location accommodates a 6.5 inch speaker size across all listed model years. Compatible audio system types for the position include midbass and full-range replacement units. These specifications cover a range from 2003 to 2006.
| Year | Type | Size (inch) |
|---|---|---|
| 2006 | Midbass / Full-Range | 6.5 |
| 2005 | Midbass / Full-Range | 6.5 |
| 2004 | Midbass / Full-Range | 6.5 |
| 2003 | 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 behind rear seat location in the Mercedes-Benz CLK55 AMG sits within the rear cabin area, positioned low and behind the passenger seating plane, which influences how sound projects into the cabin.
- A speaker mounted behind the rear seat faces physical constraints typical of enclosed or semi-enclosed cavities, where airspace is limited and panel depth can restrict the excursion capability of larger drivers.
- 6.5-inch speakers occupy a mid-sized driver diameter that balances cone surface area with fitment requirements in shallow or compact enclosure spaces, as found in rear shelf and behind-seat installations.
- The 6.5-inch cone diameter produces sufficient radiating area to move air effectively in the lower and mid frequencies without requiring the deep mounting depth associated with larger woofer formats.
- A mounting depth consideration applies specifically to the CLK55 AMG behind rear seat position, where the structural panel thickness and available cavity behind the seat back determine whether a given driver's frame and magnet assembly can be accommodated.
- Midbass drivers in a 6.5-inch format are designed to handle frequencies roughly between 80 Hz and 500 Hz, reinforcing the lower midrange and upper bass registers that contribute to body and warmth in reproduced audio.
- In a behind-seat location, a midbass driver operates in a position where direct high-frequency projection toward the listening area is limited, making the midbass type acoustically suited to a range that does not rely on line-of-sight directivity.
- Full-range drivers cover a wider frequency band, typically from around 60 Hz up to 20 kHz, using a single cone and sometimes an integrated tweeter or whizzer cone to extend treble output.
- When a full-range driver is placed behind the rear seat of the CLK55 AMG, the high-frequency content produced by the driver may experience absorption and diffraction as sound passes over and around the seat structure before reaching front occupants.
- The compatibility of both midbass and full-range types with the 6.5-inch position indicates the mounting cutout and depth in the CLK55 AMG behind rear seat panel are sized to accept the physical footprint common to both driver types in the 6.5-inch category.
- Full-range drivers used in rear-of-seat placements can supplement a speaker system by filling mid and bass frequencies in the rear acoustic field, even when upper frequency dispersion is partially obstructed by seat materials.
- The 6.5-inch specification applies uniformly across the 2003 through 2006 model years of the CLK55 AMG, indicating no structural change to the behind rear seat speaker location was made during that production span.
