Ford Fusion Rear Deck Center Speaker Size
The Ford Fusion rear deck center accommodates a 3.5 inch speaker size and 4 inch speakers, supporting both unique sizes across the model's production range. Midrange units are the compatible speaker types for the rear deck center position. These specifications cover the 2010 to 2020 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2020 | Midrange | 3.5 |
| 2019 | Midrange | 3.5 |
| 2018 | Midrange | 3.5 |
| 2017 | Midrange | 3.5 |
| 2016 | Midrange | 3.5 |
| 2015 | Midrange | 3.5 |
| 2014 | Midrange | 3.5 |
| 2013 | Midrange | 3.5 |
| 2012 | Midrange | 4 |
| 2011 | Midrange | 4 |
| 2010 | Midrange | 4 |
Speaker Types
| Type | Description |
|---|---|
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
Additional Notes
- The rear deck center position in the Ford Fusion is a dedicated center-channel location mounted along the rear parcel shelf, between the two rear side speaker positions, facing upward toward the cabin interior.
- A center speaker mounted on the rear deck projects sound forward into the passenger cabin from behind, a placement that affects imaging depth and rear-fill balance in the overall speaker stage.
- The 3.5 inch driver size specified for 2013 through 2020 model years indicates a compact cone diameter, which limits low-frequency extension but allows tighter spatial packaging within the constraints of the rear deck center cutout.
- A 3.5 inch midrange driver in a rear deck center position is suited to reproducing vocal frequencies and upper midrange content, roughly in the range of 300 Hz to 5 kHz, without relying on significant cone surface area for output.
- The 4 inch driver size specified for 2010 through 2012 model years occupies a slightly larger mounting footprint and delivers marginally greater cone surface area, which contributes to modestly deeper low-midrange response compared to the 3.5 inch specification.
- A 4 inch midrange driver in the rear deck center position of the Ford Fusion handles the same general midrange frequency band as the 3.5 inch variant, with the additional cone area allowing somewhat more efficient energy output at lower midrange frequencies.
- Midrange is the sole compatible speaker type listed across all specified model years, indicating the rear deck center location is not dimensioned or acoustically intended for full-range, woofer, or tweeter drivers.
- A midrange speaker type is designed without the internal crossover components of a coaxial driver and without the subwoofer-grade suspension of a woofer, making a dedicated midrange unit appropriate for band-limited center-channel reinforcement in a rear-deck application.
- The rear deck surface, typically constructed from a rigid panel above the trunk, acts as the mounting baffle for the center speaker, and the rigidity of the material affects resonance behavior around the driver's operating frequency range.
- Because the rear deck center position faces upward rather than forward, sound from a midrange driver installed there reaches the front occupants after reflecting off the rear window glass, a factor that influences tonal coloration and time alignment relative to the front speakers.
- The shift from a 4 inch to a 3.5 inch specification between the 2012 and 2013 Ford Fusion model years reflects a change in the rear deck center mounting cutout dimension, meaning a 4 inch driver is not a direct fit replacement in 2013 and later applications.
