Mitsubishi Van Dashboard Speaker Size
The Mitsubishi Van dashboard location accommodates a 4 inch speaker size. Midrange units represent the compatible audio type for the system. These specifications cover the 1990 model year.
| Year | Type | Size (inch) |
|---|---|---|
| 1990 | 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 a van positions speakers within the instrument panel, typically at ear level for front passengers, where direct sound projection toward the listening area is most immediate.
- Dashboard speaker cavities are generally shallow-depth enclosures, which constrains the mounting depth and overall driver displacement available for any speaker installed in the position.
- The 4-inch driver diameter places the speaker in a small-format category, suited to reproducing frequencies in the upper-midrange and presence region, roughly from around 500 Hz up to several kilohertz, depending on crossover configuration.
- A 4-inch speaker in a dashboard location benefits from the reflective surface of the instrument panel, which can reinforce forward sound projection toward the occupants seated immediately behind the dashboard.
- The midrange type is a dedicated band-pass driver designed to handle the frequency region most critical to vocal intelligibility and instrument presence, typically centered between approximately 300 Hz and 5 kHz.
- The 1990 Mitsubishi Van dashboard speaker position specifies midrange as the compatible type, meaning the driver in that location is intended to operate as part of a multi-way system where low-frequency and high-frequency reproduction are handled by separate drivers elsewhere in the vehicle.
- Midrange drivers are generally built with cone materials and surround compliance tuned to minimize distortion across the vocal band, where the human ear is most sensitive to coloration.
- A 4-inch midrange in a dashboard mounting typically lacks the cone area to produce significant bass output, reinforcing the functional designation as a band-specific driver rather than a full-range unit.
