Ford Transit Side Cargo Area Doors Speaker Size
The Ford Transit side 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 speakers. 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 side cargo area door locations accept 6.5-inch speakers across the 2015 through 2018 model years.
- A 6.5-inch driver occupies a mid-sized mounting footprint, requiring a sufficient door cavity depth and baffle surface area to accommodate both the basket diameter and rear magnet structure without obstruction from door hardware or structural reinforcements.
- The side cargo area doors in a van body style are typically positioned along the lower lateral walls of the cabin, placing speaker drivers at a height and angle that projects sound horizontally across the cargo or passenger space rather than upward toward a headliner.
- At 6.5 inches, a driver's cone surface area supports useful low-frequency output, generally reproducing frequencies from roughly 60 Hz upward, which makes the mounting location relevant for mid and upper-bass reproduction within the cargo area.
- The midbass type, listed as compatible for the Ford Transit side cargo area door, is a driver engineered specifically to handle the lower-midrange and upper-bass frequency bands, typically from around 60 Hz to 500 Hz, and is not designed to extend into high-frequency reproduction.
- A midbass driver in a door-mounted cargo area location operates without the high-frequency extension needed for dialogue or cymbal reproduction, functioning instead as part of a multi-component system where a separate tweeter handles treble frequencies.
- The full-range type, also listed as compatible for this location, is designed to reproduce a broader spectrum spanning bass, midrange, and partial treble frequencies within a single driver, reducing the need for additional components in the cargo area doors.
- Full-range drivers at 6.5 inches in a side cargo door position face acoustic challenges related to early high-frequency roll-off caused by the relatively large cone mass, which limits treble extension compared to dedicated smaller-diameter drivers.
- The lateral door placement of the side cargo area on the Ford Transit positions the speaker baffle facing inward toward the vehicle interior, which affects the off-axis frequency response experienced by occupants seated away from the door plane.
- Door-mounted locations in cargo-area applications are subject to mechanical vibration from road noise and door actuation, which can influence driver resonance behavior and the structural integrity of the mounting surface over time.
