Ram ProMaster City Front Door Panel Speaker Size
The Ram ProMaster City front door panel accommodates a 6.5 inch speaker size across all listed model years. Compatible speaker types for the location include midbass and full-range units. The specifications cover a range of years from 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 front door panel location places speakers within the lower portion of the cabin doors, positioning the drivers at approximately seat-level height relative to occupants.
- Door panel mounting exposes speakers to potential moisture ingress, vibration from road surfaces, and magnetic interference from window regulator motors integrated into the door structure.
- The Ram ProMaster City front door panel accepts a 6.5-inch driver across all listed model years, meaning the mounting cutout diameter and depth clearance are consistent throughout the 2015-2018 production span.
- A 6.5-inch diameter driver produces a cone surface area sufficient to move enough air for meaningful low-midrange output, with a usable frequency range typically spanning from around 60 Hz up through several kilohertz depending on the specific driver design.
- The physical depth of a 6.5-inch driver requires adequate rear clearance within the door cavity to avoid contact with the inner door skin or window regulator hardware during installation.
- Midbass drivers in a front door panel location are optimized to reproduce the lower-midrange and upper-bass frequencies, generally operating between approximately 80 Hz and 500 Hz, serving primarily to anchor the low-end foundation of the audio spectrum within the cabin.
- Because midbass drivers are designed to operate within a limited frequency band, front door panel installations using this type typically function alongside a separate high-frequency driver elsewhere in the vehicle.
- Full-range drivers are designed to reproduce a broader frequency spectrum from a single cone, covering bass, midrange, and a portion of high frequencies, making them a self-contained solution for the front door panel position.
- The front door panel location places the speaker baffle on a surface that is angled away from the listening position, which affects high-frequency dispersion more than low-frequency output due to the directional nature of higher frequencies.
- Door panel installations rely on the door cavity itself to act as an enclosure, and the volume and seal quality of that cavity influence the low-frequency response of any 6.5-inch driver mounted in the Ram ProMaster City front door.
