Plymouth Colt Dashboard Speaker Size
The Plymouth Colt dashboard accommodates a 4 inch speaker size across all listed model years. Midrange units serve as the compatible replacement types for the audio system. These specifications cover the years 1990 to 1994.
| Year | Type | Size (inch) |
|---|---|---|
| 1994 | Midrange | 4 |
| 1993 | Midrange | 4 |
| 1992 | Midrange | 4 |
| 1991 | Midrange | 4 |
| 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 speaker location in the Plymouth Colt sits within the instrument panel, a mounting position that places drivers at a relatively close listening distance and at a height roughly aligned with the lower windshield area.
- Dashboard enclosures are typically shallow and space-constrained, which limits the available depth for speaker basket and magnet assembly.
- A 4-inch speaker diameter suits a dashboard cavity because the mounting footprint is small enough to fit within the limited surface area of a typical instrument panel without requiring cutouts that would compromise structural integrity.
- At 4 inches, the cone surface area is sufficient to reproduce frequencies in the midrange band without requiring the larger excursion distances that low-frequency reproduction demands, making the size mechanically appropriate for a shallow dashboard mount.
- Midrange speakers are designed to handle the frequency band generally spanning from around 500 Hz to 5,000 Hz, which covers the core of the human vocal range and many fundamental musical tones.
- In a dashboard position, midrange drivers benefit from forward-facing projection toward the occupants, as the instrument panel typically angles rearward and upward, directing sound into the cabin rather than toward the floor or doors.
- Midrange speakers are a distinct driver type from full-range units; the Plymouth Colt dashboard location, per the specifications, does not use woofers or tweeters, meaning the 4-inch midrange handles a defined slice of the frequency spectrum rather than the full audio range.
- Because midrange drivers are not engineered for low-frequency excursion, the absence of a large magnet structure in many 4-inch midrange units reduces the mounting depth required, which is consistent with the spatial limitations typical of dashboard installations.
- The 4-inch midrange designation for the Plymouth Colt dashboard applies consistently across all 5 model years listed in the specifications, from 1990 through 1994.
- Dashboard placement positions midrange drivers closer to the windshield glass than door-mounted speakers, and glass reflections at these frequencies can influence the perceived imaging of midrange content within the cabin.
