Jaguar XJS Rear Door Panel Speaker Size
The Jaguar XJS rear door panel accommodates a 5.25 inch speaker size across all listed model variants. Compatible audio types for the location include midbass and full-range system units. These specifications cover the 1986 to 1996 model range.
| Year | Type | Size (inch) |
|---|---|---|
| 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 |
| 1988 | Midbass / Full-Range | 5.25 |
| 1987 | Midbass / Full-Range | 5.25 |
| 1986 | 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 rear door panel location on the Jaguar XJS accommodates a 5.25 inch speaker across all listed model years, indicating a consistently sized mounting cavity within the door structure throughout the production span covered by the specifications.
- A 5.25 inch speaker occupies a mid-sized cone diameter, producing a cone surface area that supports meaningful low-midrange and upper-bass reproduction while remaining physically compact enough to fit within the spatial constraints of a door panel cutout.
- Door panel locations position speakers within an enclosed cavity backed by the door's interior sheet metal, which affects rear-wave reflection and bass loading, making the physical depth and baffle characteristics of the mounting point relevant to speaker performance.
- The midbass type is a driver engineered to handle the lower portion of the midrange and upper bass frequencies, typically spanning roughly 80 Hz to 500 Hz, where punch, warmth, and the lower harmonics of vocals and instruments are reproduced.
- In a rear door panel location, a midbass driver benefits from the partial acoustic enclosure formed by the door cavity, which can reinforce low-frequency output without requiring a dedicated sealed or ported enclosure behind the cone.
- The full-range type is a single driver designed to reproduce a wide frequency band, generally from the upper bass through the high frequencies, consolidating multiple frequency roles into 1 unit within the door panel opening.
- A 5.25 inch full-range driver in a door panel position handles treble reproduction through an integrated cone or whizzer cone, though the off-axis high-frequency dispersion from a door-mounted location affects how treble reaches rear-seat passengers.
- The Jaguar XJS rear door panel speaker location, confirmed by the 5.25 inch specification, reflects a physical cutout dimension that determines the maximum basket diameter and mounting depth a replacement or aftermarket driver must conform to.
- Both compatible types listed - midbass and full-range - share the same 5.25 inch mounting diameter, meaning the choice between the 2 types is governed by the intended acoustic role rather than by any difference in the physical fit dimension.
- A midbass driver in the rear door panel typically functions as part of a multi-way system, working in conjunction with a separate tweeter mounted elsewhere in the cabin to cover the upper frequencies the midbass driver does not reproduce.
