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. |
| 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 front door panel is a lateral mounting position within the cabin, placing speakers at roughly seat-level height along the lower portion of the door interior.
- Door panel installations are typically recessed into molded cavities within the door card, meaning speaker depth and diameter must conform to the existing cutout dimensions and available clearance behind the panel.
- The front door panel location places speakers in proximity to the listening position, which influences staging and imaging for front-channel audio reproduction.
- A 1 inch tweeter in the front door panel of the Mercedes-Benz E320 handles high-frequency content, generally operating above 2,000 Hz, where wavelengths are short enough that small diaphragm size is acoustically appropriate for detail and dispersion.
- The front door panel positions the 1 inch tweeter at door level, which is a lower vertical axis than is typical for high-frequency sources, affecting the perceived soundstage height within the cabin.
- A 6.5 inch driver in a midbass or full-range role handles the mid and upper-bass frequencies, generally from around 60 Hz to 5,000 Hz depending on crossover configuration, with the larger cone area supporting greater air displacement relative to smaller diameters.
- The 6.5 inch size in a front door panel benefits from the door cavity acting as a partial enclosure, which can reinforce low-frequency output from the driver.
- A 5.25 inch driver in the midbass or full-range role covers a similar frequency range to the 6.5 inch but with reduced cone area, resulting in somewhat less low-frequency displacement and output at equivalent power levels.
- The 5.25 inch format represents a physically smaller mounting footprint, which corresponds to a different factory cutout dimension in the door panel compared to the 6.5 inch configuration.
- In years where both a 1 inch tweeter and a 6.5 inch midbass or full-range driver are listed for the front door panel, the door panel accommodates 2 separate mounting locations, one for each driver size.
- In 2003, the front door panel of the Mercedes-Benz E320 is listed with 3 compatible speaker sizes - 1 inch, 5.25 inch, and 6.5 inch - indicating multiple distinct mounting positions or aperture options within the same door panel location.
- Full-range drivers are designed to reproduce a wide frequency band from a single driver without requiring a crossover, while midbass drivers are intended to operate within a band-limited range, typically crossed over to a tweeter above and a subwoofer below.
