Mercedes-Benz CLK550 Behind Rear Seat Speaker Size
The Mercedes-Benz CLK550 behind rear seat location accommodates a 6.5 inch speaker size. Compatible types for the audio system include midbass and full-range replacement units. These specifications cover the years 2007 to 2009.
| Year | Type | Size (inch) |
|---|---|---|
| 2009 | Midbass / Full-Range | 6.5 |
| 2008 | Midbass / Full-Range | 6.5 |
| 2007 | 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 CLK550 accommodates a 6.5 inch speaker opening across the 2007, 2008, and 2009 model years.
- A 6.5 inch driver occupies a mid-sized cone area that balances low-frequency extension with upper midrange reproduction, making the behind rear seat position functional for a wide portion of the audible spectrum.
- The behind rear seat position places speakers at a low, rearward point in the cabin, which influences soundstage depth and the perceived directionality of bass and lower midrange frequencies reaching front occupants.
- At 6.5 inches, the cone surface area is sufficient to move enough air for meaningful midbass output, typically covering frequencies from roughly 60 Hz up through 500 Hz or higher depending on crossover configuration.
- The midbass type listed as compatible concentrates on lower midrange and upper bass frequencies, and in a behind rear seat location, a midbass driver reinforces the sense of weight and warmth in the overall system without extending into the highest frequencies.
- A full-range type, also listed as compatible, handles low, mid, and high frequencies from a single driver, allowing the behind rear seat position in the Mercedes-Benz CLK550 to operate without a dedicated tweeter in that location.
- Because the behind rear seat location is physically separated from the listening position of front occupants, a full-range driver installed there may produce high-frequency output that is less directionally integrated with the front stage compared to a midbass driver used with a low-pass crossover.
- The 6.5 inch diameter is a standard aftermarket and OEM size, meaning the mounting depth and basket dimensions of many commercially available 6.5 inch drivers are designed to fit within the spatial constraints typical of this class of installation location.
- Mounting a speaker behind the rear seat generally requires attention to enclosure conditions, as the space behind the seat panel can act as an open or semi-open baffle, which affects the low-frequency efficiency and resonance behavior of a 6.5 inch cone driver.
