Ford Transit Rear Cargo Area Doors Speaker Size
The Ford Transit rear cargo area doors accommodate a 6.5 inch speaker size across all listed model years. Compatible types for the location include midbass and full-range units. These specifications cover the years 2015 to 2018.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Midbass / Full-Range | 6.5 |
| 2017 | Midbass / Full-Range | 6.5 |
| 2016 | Midbass / Full-Range | 6.5 |
| 2015 | 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 Ford Transit rear cargo area door locations accept 6.5-inch speakers across the 2015 through 2018 model years.
- Rear cargo area door mounting positions are typically recessed within the door panel structure, requiring speakers with specific depth clearances to avoid contact with the door's internal hardware and window mechanisms.
- Cargo area door locations place speakers at a lower vertical position relative to ear level, a geometry that affects the perceived directionality of mid and upper frequencies reaching the listening area.
- A 6.5-inch driver carries a cone surface area large enough to move substantial air volume, which supports the reproduction of lower midrange and upper bass frequencies at this rear-cabin position.
- The midbass type is a speaker designed to handle the frequency band roughly between 80 Hz and 500 Hz, prioritizing controlled low-midrange output over extended high-frequency reproduction, which suits a rear door position where the enclosure depth and panel materials influence bass loading.
- A full-range speaker is designed to cover a broad frequency span, typically from around 60 Hz up to 20 kHz, using a woofer cone supplemented by a whizzer cone or integrated tweeter to extend treble response without a separate high-frequency driver.
- In a cargo door location, a full-range 6.5-inch speaker handles the entire audible spectrum from a single mounting point, which is relevant where no additional tweeters are installed at the rear of the vehicle.
- Cargo area doors on a van-style vehicle like the Ford Transit are structurally heavier and less resonant than passenger car doors, a characteristic that can affect the amount of unwanted panel vibration coupling into the speaker's output at high excursion levels.
- The 6.5-inch diameter designation refers to the speaker's nominal cone diameter, while the actual cutout requirement and overall frame diameter are distinct measurements that determine fitment within the Ford Transit 2015-2018 rear cargo door opening.
- Midbass drivers in a door location typically feature stiffer suspensions and smaller excursion-range tweeters are omitted entirely, making them better suited for systems where a separate amplifier or dedicated tweeter handles upper frequencies elsewhere in the cabin.
