Ram 3500 Rear Roof Speaker Size
The Ram 3500 rear roof location accommodates a 2.5 inch speaker size, with all positions supporting 2.5 inch units across the model range. Midrange is the compatible audio type for the system. These specifications cover the 2011 to 2018 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 in the Ram 3500 places speakers overhead and toward the rear of the cabin, a location that distributes sound downward and forward into the passenger seating area.
- Overhead mounting, as found in a rear roof location, creates a wide horizontal dispersion angle relative to seated occupants, which differs from door-mounted or pillar-mounted positions where sound travels laterally.
- The 2.5 inch diameter is a small cone size, and small cones move less air than larger drivers, making them physically suited to flush-mounted overhead enclosures where depth and excursion space are limited by headliner thickness.
- A 2.5 inch driver in a roof-mounted position reinforces upper-cabin audio presence without the low-frequency output that would require a larger cone and deeper enclosure.
- The midrange type is designed to reproduce frequencies roughly between 300 Hz and 5,000 Hz, covering vocals, instruments, and the presence region of the audio spectrum.
- In a rear roof location, a midrange driver at 2.5 inches handles the frequency band where human speech and most musical midrange content resides, contributing to intelligibility for rear-seat occupants.
- Midrange speakers do not require a subwoofer-style enclosure or passive crossover tuned for deep bass, which aligns with the spatial constraints of a headliner-integrated mounting point in the Ram 3500.
- The Ram 3500 rear roof speaker opening accommodates a 2.5 inch midrange driver across the 2011 through 2018 model years, indicating a consistent baffle cutout and depth specification throughout that production range.
