Ford Taurus D-Pillar Speaker Size
The Ford Taurus D-Pillar accommodates a 6.5 inch speaker size and 6.75 inch speakers across the model's production span. Compatible types for these units include midbass and full-range audio configurations. These specifications cover the 1991 to 1992 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 1992 | Midbass / Full-Range | 6.5 |
| 1991 | Midbass / Full-Range | 6.75 |
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 D-pillar location in the Ford Taurus positions speakers at the rearmost structural column of the vehicle, placing drivers near the rear window and furthest from front-seat occupants in the cabin.
- A D-pillar mounting position typically orients speakers to radiate sound toward the rear of the cabin, contributing to rear-fill and spatial depth in the overall soundstage.
- The 1991 Ford Taurus D-pillar accepts a 6.75-inch driver, a diameter that supports a larger cone surface area compared to the 1992 fitment, which correlates with greater low-frequency displacement capability at that location.
- The 1992 Ford Taurus D-pillar is sized for a 6.5-inch driver, a format widely associated with a balance between low-midrange output and physical compactness within constrained mounting cavities.
- Both the 6.5-inch and 6.75-inch formats are mid-sized woofer diameters, suited to reproducing frequencies roughly in the range of 60 Hz to 5 kHz, making them appropriate for rear-fill applications where full-spectrum coverage is desired without a dedicated subwoofer at the location.
- Midbass drivers, listed as a compatible type for both years, are optimized for the lower portion of the midrange and upper bass frequencies, typically operating between approximately 80 Hz and 500 Hz, emphasizing body and warmth in audio reproduced from the rear of the cabin.
- Full-range drivers, also listed as a compatible type for both years, are designed to reproduce a wide frequency span from bass through treble within a single driver, making them a functional choice for a D-pillar position where adding a separate tweeter may not be practical.
- The D-pillar's structural role as a rear roof support column means the mounting depth and baffle geometry are constrained by the pillar's cross-section, which influences the maximum magnet and basket depth a compatible driver can occupy.
- Because the 1991 and 1992 Ford Taurus accept different speaker diameters at the D-pillar, the mounting hole diameter and baffle cutout dimensions differ between the 2 model years at that specific location.
