Ram 2500 Rear Roof Speaker Size
The Ram 2500 rear roof location accommodates a 2.5 inch speaker size across all listed model years. Midrange units are the compatible speaker type for the audio system at that position. These specifications cover the 2011 to 2018 range of model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Midrange | 2.5 |
| 2017 | Midrange | 2.5 |
| 2016 | Midrange | 2.5 |
| 2015 | Midrange | 2.5 |
| 2014 | Midrange | 2.5 |
| 2013 | Midrange | 2.5 |
| 2012 | Midrange | 2.5 |
| 2011 | Midrange | 2.5 |
Speaker Types
| Type | Description |
|---|---|
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
Additional Notes
- The rear roof position on the Ram 2500 places speakers at an elevated, centrally overhead location within the cabin, which orients sound projection downward toward rear passengers rather than toward the front of the vehicle.
- A roof-mounted speaker location is typically shallow in depth, as the headliner and roof panel assembly allow minimal clearance for speaker basket depth, making driver depth a critical physical constraint for fitment.
- The 2.5 inch diameter specified for the Ram 2500 rear roof location reflects the compact footprint available within the roof panel cavity, where structural framing and headliner thickness limit the usable mounting diameter.
- A 2.5 inch driver produces sound primarily in the upper midrange and presence frequencies, roughly from around 500 Hz into the several-kilohertz range, which suits a supplemental fill role rather than full-range reproduction.
- The midrange type specified for the Ram 2500 rear roof is a driver designed to reproduce the frequency band where vocals, speech intelligibility, and instrumental presence are concentrated, making directional placement directly above rear passengers acoustically relevant.
- Midrange drivers, unlike woofers or tweeters, are engineered without the passive crossover network of a coaxial or the frequency extension of a full-range driver, and are instead intended to operate within a defined band when paired with an active or passive crossover system.
- At 2.5 inches, the cone area is small enough that high-frequency dispersion is relatively wide, allowing a roof-mounted position to cover a broad seating zone below without severe off-axis coloration within the midrange band.
- The rear roof location is physically separated from the primary front soundstage, so the midrange drivers at this position function within a system context as rear fill or rear staging elements rather than primary imaging sources.
- The consistent specification of 2.5 inch midrange drivers across all listed model years from 2011 through 2018 indicates a stable mounting cavity dimension at the rear roof location throughout that production span of the Ram 2500.
