Mercedes-Benz 280C Dashboard Speaker Size
The Mercedes-Benz 280C dashboard accommodates a 4 inch speaker size across all listed model years. Compatible types for the location include midrange audio units. The specifications cover the years 1973 to 1976.
| Year | Type | Size (inch) |
|---|---|---|
| 1976 | Midrange | 4 |
| 1975 | Midrange | 4 |
| 1974 | Midrange | 4 |
| 1973 | 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 dashboard location in the Mercedes-Benz 280C positions speakers within the instrument panel, a shallow, enclosed cavity that constrains both depth and baffle area available for driver mounting.
- A 4-inch speaker diameter reflects a compact cone surface area, which corresponds to limited low-frequency displacement but sufficient pistonic movement for mid-band audio reproduction.
- Dashboard placement situates speakers close to the front occupants and at ear level, a geometry that reinforces direct sound delivery with minimal reflective path from the source to the listener.
- The 4-inch form factor in a dashboard cavity is subject to the acoustic loading effects of the enclosure formed by the instrument panel structure, which influences the speaker's effective frequency response in practice.
- Midrange drivers are designed to reproduce the frequency band approximately between 500 Hz and 5,000 Hz, covering the core of vocal intelligibility and the fundamental tones of most instruments.
- A midrange driver in the Mercedes-Benz 280C dashboard operates without the low-excursion demands of bass reproduction, which is consistent with the limited physical depth typically available behind a dashboard fascia.
- Midrange speakers use a relatively stiff, lightweight cone and a moderate surround to maintain accurate pistonic motion across the mid-band without the mechanical compliance required for low-frequency work.
- At dashboard height, a midrange driver benefits from a relatively unobstructed radiation path toward the passenger cabin, allowing the mid-band frequencies to propagate with less diffraction interference than speakers mounted lower in door panels.
- The 4-inch size produces a directional pattern that broadens across the midrange band, meaning higher mid frequencies remain more directional while lower midrange frequencies disperse more widely within the cabin.
- Across the 1973 through 1976 model years of the 280C, the dashboard speaker size of 4 inches and the compatible type of midrange remain uniform, indicating a consistent speaker cavity design across that production span.
