Mercedes-Benz CL63 AMG Rear Door Panel Speaker Size
The Mercedes-Benz CL63 AMG rear door panel accommodates a 4 inch speaker size. Midrange units represent the compatible speaker types for the location. The specifications cover a range of years from 2008 to 2014.
| Year | Type | Size (inch) |
|---|---|---|
| 2014 | Midrange | 4 |
| 2013 | Midrange | 4 |
| 2012 | Midrange | 4 |
| 2011 | Midrange | 4 |
| 2010 | Midrange | 4 |
| 2009 | Midrange | 4 |
| 2008 | Midrange | 4 |
Speaker Types
| Type | Description |
|---|---|
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
Additional Notes
- The rear door panel location places speakers within the lower half of the door structure, where the driver sits in proximity to the listener's ear level at a downward or side-facing angle depending on enclosure design.
- Door panel installations are generally shallow-mount environments, meaning speaker depth clearance is constrained by the door's internal framework, wiring harnesses, and window mechanisms.
- A 4 inch speaker diameter corresponds to a relatively compact cone surface area, which directly influences the frequency range the driver can efficiently reproduce, favoring the upper midrange and lower midrange bands over deep bass reproduction.
- The 4 inch size in a rear door panel position means the speaker operates within a partially enclosed cavity formed by the door shell, which can influence low-frequency boundary reinforcement to a limited degree.
- Midrange speakers are designed to handle the frequency band approximately between 300 Hz and 5 kHz, covering the core presence of vocals, instruments, and harmonic content that the human ear is most sensitive to.
- In a rear door panel location, a midrange driver's directional radiation pattern projects sound toward the cabin interior, where reflections from seat surfaces and interior panels shape the perceived soundstage for rear passengers.
- The Mercedes-Benz CL63 AMG rear door panel, using a 4 inch midrange, positions the speaker where crossover interaction with subwoofers or tweeters elsewhere in the vehicle determines the effective bandwidth the midrange driver is asked to reproduce.
- A 4 inch midrange driver has a relatively controlled dispersion pattern compared to larger woofer-sized drivers, meaning high-frequency components within its range project more narrowly as frequency increases.
- The rear door panel location subjects speakers to environmental factors including door slam vibration, temperature fluctuation, and potential moisture intrusion, all of which are mechanical considerations for speaker mounting and surround material selection.
- Midrange drivers typically operate without needing to move large volumes of air, making the limited internal volume of a door panel cavity a less critical constraint for midrange reproduction than for bass-range drivers.
