The Plymouth Laser dashboard accommodates a 4 inch speaker size in the dashboard location. Midrange units are the compatible audio system replacement types for the dashboard. 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 location in the Plymouth Laser positions speakers along the forward-most horizontal surface of the interior, placing audio output at windshield level and directing sound upward and toward the cabin.
- A 4-inch speaker diameter is a compact size suited to shallow, space-constrained cavities, which is consistent with the limited depth typically available beneath a dashboard panel.
- The 4-inch cone area produces a relatively focused sound projection, which in a dashboard position means audio originates near the front of the cabin and travels rearward toward occupants.
- Midrange drivers are designed to reproduce frequencies approximately between 500 Hz and 5,000 Hz, covering the core band of human speech, vocals, and the fundamental tones of most instruments.
- In a dashboard installation, a midrange driver at 4 inches benefits from proximity to ear level when seated, allowing midrange frequencies to reach the listener with minimal obstruction from seat structures or door panels.
- The Plymouth Laser dashboard accepts only midrange-type speakers across all listed model years, meaning the location is not specified for woofers or tweeters, which occupy lower and higher frequency roles respectively.
- A 4-inch midrange in the Plymouth Laser dashboard works within a shallow enclosure environment, where rear-wave management is constrained by dashboard structure rather than a purpose-built enclosure.
- Midrange drivers in a forward-mounted position, such as the Plymouth Laser dashboard, contribute to stereo imaging by anchoring the perceived sound stage near the front of the vehicle cabin.
