Mitsubishi Eclipse Rear Door Panel Speaker Size
The Mitsubishi Eclipse rear door panel accommodates a 6x9 inch speaker size and 6.5 inch speakers across its model range. Compatible types for the audio system include full-range units, as well as midbass replacement units for certain years. These specifications cover a range of years from 1990 to 2011.
| Year | Type | Size (inch) |
|---|---|---|
| 2011 | Full-Range | 6x9 |
| 1995 | Full-Range | 6x9 |
| 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 Mitsubishi Eclipse rear door panel is a vertical surface-mounted location, positioning speakers within the lower portion of the passenger cabin doors, typically directing sound laterally across the cabin floor level.
- Door panel installations are generally constrained by the interior door cavity depth, which determines the maximum speaker basket depth and magnet clearance available behind the mounting surface.
- The 6x9 inch oval format found in the Mitsubishi Eclipse rear door panel specifications for 1995 and 2011 models uses an elongated cone surface that produces a larger radiating area than a standard round speaker of similar height, extending low-frequency output within the door panel enclosure.
- The 6x9 inch format's oval geometry creates a directional dispersion pattern that differs from round drivers, with horizontal and vertical dispersion angles varying due to the asymmetric cone dimensions relative to the door panel orientation.
- Full-range compatibility listed for the 6x9 inch fitment means a single driver is designated to reproduce the entire audible frequency spectrum assigned to the rear door location, from low bass through upper midrange and treble, without a dedicated crossover network.
- The 6.5 inch round format listed for model years 1990 through 1994 is a circular driver with a symmetrical dispersion pattern, distributing midrange and midbass frequencies evenly across the cabin from the rear door mounting position.
- At 6.5 inches, the driver cone area supports midbass reproduction, which covers the lower midrange and upper bass frequencies, roughly spanning the range where male vocals, bass guitar, and kick drum fundamentals are present.
- Midbass compatibility listed for the 6.5 inch rear door fitment in the Mitsubishi Eclipse (1990-1994 models) indicates the driver is suited for operation within a frequency band rather than across the full spectrum, typically used alongside separate tweeters in a multi-driver system.
- Full-range compatibility also listed for the 6.5 inch location means the rear door cavity in those model years can accommodate a driver intended to cover broadband frequencies without a dedicated crossover, functioning as a standalone acoustic source at that position.
- The rear door panel location, being closer to the floor than dashboard or sail panel positions, affects the spatial integration of bass frequencies, as low-frequency wavelengths are less directional and propagate more uniformly through the cabin regardless of mounting height.
- Door panel speaker cutouts are surrounded by the door's structural frame, which can contribute to cabinet-like back-volume behavior affecting the low-frequency resonance of whichever driver occupies the mounting position.
