Ford Expedition A-Pillar Speaker Size
The Ford Expedition A-Pillar accommodates a 0.75 inch speaker size across all listed model years. The compatible speaker type for the A-Pillar location is the tweeter. These specifications cover a range of years from 2018 to 2024.
| Year | Type | Size (inch) |
|---|---|---|
| 2024 | Tweeter | 0.75 |
| 2023 | Tweeter | 0.75 |
| 2022 | Tweeter | 0.75 |
| 2021 | Tweeter | 0.75 |
| 2020 | Tweeter | 0.75 |
| 2019 | Tweeter | 0.75 |
| 2018 | Tweeter | 0.75 |
Speaker Types
| Type | Description |
|---|---|
| Tweeter | A small driver built for high frequencies, typically from about 2,000 Hz to 20,000 Hz. It adds treble detail and clarity and is usually mounted near ear level or aimed at the listener. |
Additional Notes
- The A-pillar location sits at the forward upper corners of the cabin, where the windshield frame meets the front doors, positioning speakers at ear level and angled toward the listening area.
- Mounting within the A-pillar places speakers in a structurally narrow, trim-lined cavity, which limits the physical diameter of any driver that can be installed there.
- A 0.75 inch driver diameter is a compact form factor suited to the confined space within A-pillar trim panels on the Ford Expedition across the 2018 through 2024 model years.
- Tweeters operate in the high-frequency range, typically from around 2,000 Hz up to 20,000 Hz or beyond, reproducing the upper register of audio content such as cymbals, vocal sibilance, and string harmonics.
- At 0.75 inches, the diaphragm surface area is small, which aligns with the acoustic requirement of a tweeter to move rapidly and accurately reproduce short-wavelength, high-frequency sound waves.
- The A-pillar position places the Ford Expedition tweeter's high-frequency dispersion point close to seated ear height, which reduces high-frequency absorption and path-length loss before sound reaches the listener.
- High-frequency sound is directional in nature, meaning the physical angle of a tweeter relative to the listening position has a meaningful effect on perceived treble clarity and stereo imaging.
- Mounting a tweeter in the A-pillar allows the driver to face rearward into the cabin at an angle that can support a wider stereo soundstage compared to door-mounted or dashboard placements.
- The 0.75 inch tweeter size is consistent across all 7 model years listed in the specifications, indicating a uniform speaker aperture in the A-pillar location for the Expedition during that production span.
