Ram ProMaster Front Door Panel Speaker Size
The Ram ProMaster front door panel accommodates a 6.75 inch speaker size across all listed model years. Compatible speaker types for the front door panel include midbass and full-range units. These specifications cover the 2014 to 2024 model year range.
| Year | Type | Size (inch) |
|---|---|---|
| 2024 | Midbass / Full-Range | 6.75 |
| 2023 | Midbass / Full-Range | 6.75 |
| 2022 | Midbass / Full-Range | 6.75 |
| 2021 | Midbass / Full-Range | 6.75 |
| 2020 | Midbass / Full-Range | 6.75 |
| 2019 | Midbass / Full-Range | 6.75 |
| 2018 | Midbass / Full-Range | 6.75 |
| 2017 | Midbass / Full-Range | 6.75 |
| 2016 | Midbass / Full-Range | 6.75 |
| 2015 | Midbass / Full-Range | 6.75 |
| 2014 | Midbass / Full-Range | 6.75 |
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 Ram ProMaster front door panel position accepts a 6.75 inch speaker across all listed model years from 2014 through 2024.
- Front door panel locations mount speakers within the lower interior door structure, positioning the driver at roughly knee-to-hip height relative to seated occupants, which places the sound source at a low angle relative to the listener's ear level.
- A 6.75 inch cone diameter provides a relatively large radiating surface area, which supports the reproduction of lower midrange and upper bass frequencies with greater efficiency than smaller cone sizes at the same location.
- The physical depth and diameter of a 6.75 inch driver require adequate door cavity depth to accommodate the basket and magnet assembly without contacting the inner door skin or window regulator hardware.
- Midbass drivers are designed to operate within approximately 80 Hz to 500 Hz, covering the upper bass and lower midrange band without extending into the high-frequency range where cone breakup and directional interference become factors.
- In a front door panel location, a midbass driver handles the frequency content most responsible for vocal body, kick drum punch, and the fundamental tones of most instruments, making the mounting position acoustically significant in a two-way or multi-amplified system.
- Full-range drivers are designed to reproduce a wide frequency band, typically from below 100 Hz up to 20 kHz, using a single cone or a cone paired with a small integrated tweeter element called a whizzer cone.
- In the Ram ProMaster front door panel, a full-range 6.75 inch driver would be expected to handle the entire audible spectrum without supplemental tweeters or subwoofers, a configuration consistent with single-speaker-per-channel factory or replacement setups.
- The 6.75 inch format is a non-standard size relative to common 6.5 inch or 7 inch diameters, so the Ram ProMaster front door panel mounting aperture dimensions are specific to the 6.75 inch bolt pattern and baffle opening.
- Door panel speaker locations in commercial vans like the ProMaster are subject to road noise interference at lower frequencies, which is acoustically relevant to the operational range of both midbass and full-range drivers seated at that position.
