Ford C-Max Rear Door Panel Speaker Size
The Ford C-Max rear door panel accommodates a 1 inch speaker size and 6.5 inch speakers across all listed model years. Compatible types for the 1 inch units include tweeters, while the 6.5 inch units support midbass and full-range audio configurations. The specifications cover the 2013 to 2018 model year range.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Tweeter | 1 |
| 2018 | Midbass / Full-Range | 6.5 |
| 2017 | Tweeter | 1 |
| 2017 | Midbass / Full-Range | 6.5 |
| 2016 | Tweeter | 1 |
| 2016 | Midbass / Full-Range | 6.5 |
| 2015 | Tweeter | 1 |
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | Tweeter | 1 |
| 2014 | Midbass / Full-Range | 6.5 |
| 2013 | Tweeter | 1 |
| 2013 | Midbass / Full-Range | 6.5 |
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. |
| 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 C-Max rear door panel accommodates 2 distinct speaker sizes simultaneously, indicating the mounting locations within the panel are designed to support a 2-way speaker arrangement at the rear doors.
- Door panel installations position speakers within an enclosed cavity, where the panel surface and surrounding trim act as a baffle, influencing how sound radiates into the cabin.
- The 6.5-inch mounting position in the rear door panel is a mid-to-lower area placement typical of door speaker locations, where the driver is physically separated from the woofer by cabin distance, affecting bass perception at the listening position.
- A 6.5-inch driver occupies a diameter sufficient to move enough air for effective reproduction of low-midrange and midbass frequencies, generally covering the range from approximately 60 Hz to 5 kHz depending on cone material and crossover configuration.
- The midbass role of a 6.5-inch driver in the rear door focuses acoustic output on frequencies where punch, warmth, and vocal body are concentrated, making the rear door a structurally significant location for lower-frequency support.
- When configured as a full-range driver, the 6.5-inch unit in the Ford C-Max rear door panel handles the entire audible spectrum assigned to that location without the assistance of a dedicated crossover-divided tweeter, relying on the driver alone for high-frequency extension.
- The 1-inch tweeter position in the rear door panel places a high-frequency driver within the door structure, where mounting height and angle relative to the listening position determine how directional the high-frequency energy is perceived by rear-seat occupants.
- A 1-inch tweeter operates efficiently in the upper frequency range, typically from around 2 kHz to 20 kHz, where wavelengths are short and directionality becomes pronounced, meaning the physical aim of the tweeter within the door panel has a measurable effect on treble clarity.
- The tweeter type is inherently directional due to the short wavelengths at high frequencies, so the geometry of the rear door panel mounting point determines how evenly high-frequency content is distributed across the rear seating area.
- The coexistence of a 1-inch tweeter and a 6.5-inch midbass or full-range driver within the same rear door panel indicates the panel contains 2 separate mounting cutouts or integrated recesses sized to each respective driver diameter.
- Door panel depth and internal clearance behind the mounting surface constrain the maximum speaker depth, a factor relevant to both the 6.5-inch and 1-inch positions since deeper baskets or tweeter housings require adequate rear clearance to avoid contact with the door's internal hardware or window mechanisms.
- The rear door panel location, as opposed to front doors or rear deck, places the speakers closer to rear passengers while increasing the physical distance from the primary front listening positions, which influences the balance between front and rear soundstage.
