Mitsubishi Precis Front Door Panel Speaker Size
The Mitsubishi Precis front door panel accommodates a 4 inch speaker size across all listed model years. Compatible types for the location include midrange audio units. These specifications cover the 1987 to 1989 system range.
| Year | Type | Size (inch) |
|---|---|---|
| 1989 | Midrange | 4 |
| 1988 | Midrange | 4 |
| 1987 | 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 front door panel location in the Mitsubishi Precis places speakers within the lower lateral section of the passenger cabin, a position that channels sound upward and inward toward occupants at seated ear level.
- Door panel mounting positions the speaker baffle flush against an interior trim surface, with the speaker cone directed into the cabin rather than toward any exterior surface.
- The door cavity behind a panel-mounted speaker functions as an acoustic enclosure, and the volume and shape of that cavity influence the low-frequency response of any driver installed there.
- A 4-inch driver operates within a relatively compact cone area, which limits low-frequency displacement but supports accurate reproduction in the upper bass and midrange bands, roughly from 200 Hz to 5 kHz depending on the driver design.
- The 4-inch diameter specified for the Mitsubishi Precis front door panel across the 1987, 1988, and 1989 model years reflects a consistent dimensional constraint within the door panel cutout and mounting ring area.
- A midrange driver is specifically designed to reproduce the frequency band most associated with vocal clarity and instrumental presence, generally spanning from around 300 Hz to 5 kHz.
- Midrange drivers typically use a relatively stiff cone with a controlled surround to maintain accurate pistonic motion across the frequencies where human speech and the fundamental harmonics of most instruments are concentrated.
- Positioning a midrange driver in the front door panel places the primary vocal and presence frequencies at a lateral angle relative to seated occupants, which influences the perceived stereo imaging width in the front of the cabin.
- The 4-inch midrange type pairing means the driver is not expected to reproduce extended low-frequency content, as the cone surface area and cabinet volume of a door panel are not optimized for subwoofer or woofer operation.
- Midrange drivers installed in door panels are commonly crossed over from frequencies below their operational range, relying on a separate subwoofer or woofer to handle bass reproduction below approximately 200 to 300 Hz.
