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. |
Additional Notes
- The rear roof position in the 2018 Ram 1500 accommodates a 1-inch speaker opening.
- A 1-inch driver at the rear roof location operates at the upper end of the audible frequency spectrum, generally reproducing high-frequency content above approximately 2,000 Hz.
- Tweeters are small-diaphragm drivers engineered specifically for high-frequency reproduction, where a compact cone or dome surface moves rapidly enough to generate treble detail, presence, and air in an audio signal.
- Placement at the rear roof positions a tweeter at an elevated point within the cabin, which allows high-frequency dispersion downward and toward the listening area across rear seating positions.
- High-frequency drivers mounted at roof level tend to project sound with a wide horizontal dispersion pattern, as treble wavelengths are short enough to radiate broadly from an elevated source without significant obstruction.
- The 2018 Ram 1500 rear roof speaker location, accepting a 1-inch tweeter, is a dedicated high-frequency position and is not dimensioned to accommodate mid-range or full-range drivers.
- A 1-inch tweeter in a rear roof mount contributes to the upper-frequency layer of a multi-speaker system, typically working in conjunction with larger drivers located elsewhere in the vehicle to cover mid and low frequencies.
