Mercedes-Benz CLS55 AMG Rear Door Panel Speaker Size
The Mercedes-Benz CLS55 AMG rear door panel accommodates a 6.5 inch speaker size. Compatible types for the location include midbass and full-range units. The specifications cover the 2006 model year.
| Year | Type | Size (inch) |
|---|---|---|
| 2006 | 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 positions speakers within the door cavity, where the speaker fires inward toward the cabin occupants, typically at a low-to-mid height relative to seated ear level.
- Door panel installations mount the speaker baffle against the inner door skin, with the basket depth extending into the door cavity, making the available depth and diameter of the door pocket a direct constraint on fitment.
- A 6.5-inch speaker occupies a mid-sized diameter that balances cone surface area with the spatial limitations common to door panel cutouts in mid-size luxury vehicles.
- The 6.5-inch cone area produces sufficient pistonic movement to reproduce lower midrange and upper bass frequencies, which are relevant in a rear door location where low-frequency reinforcement for rear-seat passengers is a primary acoustic function.
- In a rear door panel, a 6.5-inch driver is positioned closer to the floor than the listener's ears, which affects the angle of sound incidence and can influence perceived bass weight versus midrange clarity for rear occupants.
- The Mercedes-Benz CLS55 AMG rear door panel is specified for 6.5-inch drivers, meaning the factory cutout diameter and mounting hole pattern are dimensioned to that speaker size.
- A midbass driver is optimized to handle the frequency range roughly between 80 Hz and 500 Hz, reproducing lower midrange and bass fundamentals while typically lacking a dust cap or tweeter element designed for high-frequency extension.
- A full-range driver is designed to reproduce a broader spectrum, generally from bass through treble within a single cone, often incorporating a whizzer cone or similar element to extend high-frequency response from a single driver unit.
- When a midbass type is used in the rear door panel location, the high-frequency reproduction for rear-seat passengers would depend on supplementary tweeters mounted elsewhere in the rear of the vehicle.
- When a full-range type occupies the rear door panel position, the single driver handles the entire audible spectrum for that zone without requiring a dedicated separate tweeter in the same zone.
