Subaru Legacy Rear Deck Lid Speaker Size
The Subaru Legacy rear deck lid accommodates a 6.5 inch speaker size across all listed model years. Compatible types for the location include midbass and full-range audio system units. These specifications cover the years 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 rear deck lid of the Subaru Legacy is a horizontal surface positioned at the base of the rear window, sitting above the trunk cavity and behind the rear passenger seating area.
- Mounting speakers on a rear deck lid places the drivers in a rearward and upward-facing orientation, which affects how sound disperses toward the cabin interior relative to the front listening position.
- The deck lid surface typically requires a shallow to moderate mounting depth to avoid interference with the trunk space below, making driver depth a relevant physical consideration when selecting compatible speakers.
- A 6.5 inch driver occupies a mid-sized cone diameter that balances low-frequency extension with physical cabinet requirements, making the format well suited to locations where both space and output are constrained.
- In a rear deck lid position, a 6.5 inch driver produces sufficient cone area to move air effectively for the lower midrange frequencies that benefit from reinforcement behind the seated passenger.
- Midbass drivers are designed to handle the lower portion of the midrange and upper bass frequencies, typically operating in a range from approximately 80 Hz to 500 Hz, and are built with stiffer suspensions and heavier voice coils to manage that frequency demand.
- At a rear deck location, a midbass driver in a 6.5 inch format supports the low-frequency body of vocals and instruments that would otherwise lose presence without a dedicated driver near the trunk boundary.
- Full-range drivers are designed to reproduce a broad frequency spectrum from bass through treble within a single driver, typically spanning from around 60 Hz to 20 kHz, often incorporating a small whizzer cone or similar mechanism to extend high-frequency response.
- A full-range driver installed in the rear deck lid of the Subaru Legacy handles the entire audible spectrum from a single mounting point, which simplifies the passive crossover requirements for the rear channel.
- The Subaru Legacy rear deck lid accepts 6.5 inch drivers across all listed model years from 1990 through 1994, indicating a consistent cutout and mounting pattern across the full span of the first-generation Legacy sedan platform.
