Plymouth Laser Rear Door Panel Speaker Size
The Plymouth Laser rear door panel accommodates a 6.5 inch speaker size across all listed model years. Compatible speaker types for the location include midbass and full-range units. The specifications cover a range of years from 1990 to 1994.
| Year | Type | Size (inch) |
|---|---|---|
| 1994 | Midbass / Full-Range | 6.5 |
| 1993 | Midbass / Full-Range | 6.5 |
| 1992 | Midbass / Full-Range | 6.5 |
| 1991 | Midbass / Full-Range | 6.5 |
| 1990 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| 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 Plymouth Laser rear door panel location places speakers within the lower portion of the door structure, a position that couples speaker output with the door cavity, which can act as an enclosure influencing bass reinforcement and low-midrange projection.
- Door panel installations are typically flush-mounted into a recessed cutout within the door skin or panel, meaning the speaker depth and diameter must conform to the available mounting depth behind the panel surface to avoid interference with door hardware and window mechanisms.
- A 6.5 inch driver occupies a diameter range that balances cone surface area with physical fitment constraints, allowing sufficient radiating area to move air effectively for lower frequencies while remaining within the spatial limits of a standard door panel cutout.
- The 6.5 inch cone size in a door panel location supports low-midrange and upper-bass frequency reproduction, generally covering roughly 80 Hz to 5 kHz depending on the specific driver, which suits the rear door's role in filling out the lower and mid portions of the audio spectrum within the cabin.
- Rear door panel placement positions the speaker at approximately seat-level height, which affects the directional dispersion of midrange frequencies toward the listening area and influences the perceived stereo imaging from the rear of the passenger compartment.
- The midbass type is a driver optimized for the frequency band between bass and midrange, typically spanning approximately 80 Hz to 500 Hz, with a stiffer suspension and motor design suited for controlled low-end output without requiring a separate subwoofer enclosure.
- In a rear door panel location, a midbass driver reinforces the lower frequency content of music playback, complementing front-stage speakers by adding body and weight to bass-heavy program material perceived from within the vehicle cabin.
- The full-range type is a single driver designed to reproduce a broad frequency spectrum, often from around 60 Hz to 20 kHz, incorporating a cone and sometimes a whizzer cone or integrated tweeter to extend high-frequency response without requiring a separate crossover network.
- A full-range driver installed in the Plymouth Laser rear door panel location handles both midrange and treble content simultaneously, which is relevant given the door panel's proximity to rear-seat passengers who would receive direct dispersion from the driver's axis.
- The Plymouth Laser rear door panel - across the 1990 through 1994 model years - maintains the 6.5 inch cutout specification, indicating a consistent door panel cavity and mounting ring diameter throughout the production run of the model.
- Mounting a 6.5 inch speaker in a door panel requires sufficient depth clearance behind the mounting surface, as door panels contain internal reinforcement ribs, window regulator assemblies, and wiring harnesses that can restrict the available rearward space for the speaker basket and magnet structure.
- The compatibility of both midbass and full-range types within the same 6.5 inch mounting location reflects that the physical cutout diameter is the primary spatial constraint, while the acoustic type selection determines the frequency handling behavior of the installed driver.
