Geo Tracker Rear Door Panel Speaker Size
The Geo Tracker rear door panel accommodates a 5.25 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 1989 to 1997.
| Year | Type | Size (inch) |
|---|---|---|
| 1997 | Midbass / Full-Range | 5.25 |
| 1996 | Midbass / Full-Range | 5.25 |
| 1995 | Midbass / Full-Range | 5.25 |
| 1994 | Midbass / Full-Range | 5.25 |
| 1993 | Midbass / Full-Range | 5.25 |
| 1992 | Midbass / Full-Range | 5.25 |
| 1991 | Midbass / Full-Range | 5.25 |
| 1990 | Midbass / Full-Range | 5.25 |
| 1989 | Midbass / Full-Range | 5.25 |
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 Geo Tracker rear door panel is the installation location referenced across all model years in the specifications.
- A door panel location positions the speaker within a shallow, enclosed cavity formed by the door skin and inner panel, which limits the available mounting depth and constrains the physical size of compatible drivers.
- The 5.25 inch diameter is a mid-size speaker format whose cone area is sufficient to reproduce the lower midrange and upper bass frequencies that a door panel placement is commonly expected to handle.
- Door-mounted speakers radiate sound laterally toward the vehicle's interior, meaning the dispersion pattern of the installed driver interacts directly with the listening position of rear-seat occupants in the Geo Tracker.
- Midbass drivers are purpose-built to handle the frequency band roughly between 80 Hz and 500 Hz, emphasizing controlled low-to-mid frequency output with a relatively stiff cone and motor structure suited to the limited acoustic loading of a door cavity.
- Full-range drivers are designed to reproduce a wide frequency span from bass through treble within a single cone, making the driver self-sufficient without requiring a crossover network or additional tweeters in the same location.
- The 5.25 inch cone diameter produces enough radiating surface area to move air for midbass reproduction while remaining compact enough to fit the spatial constraints of a rear door panel cutout.
- In a rear door panel location, a midbass driver operating in the Geo Tracker functions as part of a multi-speaker system, typically receiving a filtered signal that excludes high frequencies handled elsewhere in the vehicle.
- A full-range driver in the same rear door panel location handles the entire audible spectrum independently, which is relevant when no dedicated high-frequency speaker is present in the rear of the vehicle.
- The door panel cavity acts as an enclosure that affects bass response, and the 5.25 inch driver's relatively moderate excursion capability is a characteristic matched to the limited internal volume typically available behind a door panel.
