Mitsubishi Precis Rear Deck Lid Speaker Size
The Mitsubishi Precis rear deck lid accommodates a 5.25 inch speaker size and 4 inch speakers, with each location supporting the respective units across the model's production span. Compatible speaker types include midbass, full-range, and midrange audio system configurations. These specifications cover the 1987 to 1994 range of model years.
| Year | Type | Size (inch) |
|---|---|---|
| 1994 | Midbass / Full-Range | 5.25 |
| 1993 | Midbass / Full-Range | 5.25 |
| 1991 | Midbass / Full-Range | 5.25 |
| 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. |
| 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 rear deck lid is a surface-mounted location positioned at the rear of the passenger cabin, typically a flat or slightly angled panel between the rear seat and the back window.
- Speakers mounted in a rear deck lid fire upward toward the rear window glass, which can cause acoustic reflections that affect sound staging and imaging.
- The Mitsubishi Precis rear deck lid accommodates 2 distinct speaker sizes across its model years: 4 inch and 5.25 inch.
- A 4-inch driver in the rear deck lid of the Mitsubishi Precis operates within a relatively shallow mounting depth, which suits the typically limited vertical clearance found in rear deck lid cavities.
- The 4-inch size is associated with midrange-only compatibility in the 1987, 1988, and 1989 model years, meaning the driver is sized to handle the vocal and instrumental frequency band, generally spanning approximately 500 Hz to 5 kHz, without extending into low bass or high treble reproduction.
- A midrange driver at the rear deck lid position reinforces the mid-frequency content of the audio signal from the rear of the cabin, contributing to overall cabin fill in that specific frequency band.
- The 5.25-inch size appears in the 1991, 1993, and 1994 model years, indicating a larger cutout diameter and typically a greater cone area than the 4-inch position, which translates to the capacity to move more air and reproduce lower frequencies.
- The 5.25-inch driver's compatibility with midbass type means the cone area is sufficient to handle frequencies in the approximate range of 80 Hz to 500 Hz, which adds low-mid warmth and weight to the sound emitted from the rear deck position.
- Full-range compatibility listed alongside midbass for the 5.25-inch position indicates the cutout and depth can also accept drivers designed to reproduce the broadest audible spectrum from a single cone, spanning from low bass through treble frequencies.
- The rear deck lid's horizontal orientation means a 5.25-inch full-range driver mounted there radiates sound upward and rearward, rather than directly toward the listener, influencing perceived directionality and soundstage depth from the rear of the cabin.
- The transition from 4-inch midrange to 5.25-inch midbass/full-range between the earlier and later model years reflects a physical change in the mounting aperture dimensions of the Mitsubishi Precis rear deck lid structure.
