Mercedes-Benz GL320 Rear Roof Speaker Size
The Mercedes-Benz GL320 rear roof location accommodates a 1 inch speaker size across all listed model years. Tweeter units are the compatible audio system replacement type for the rear roof. These specifications cover the 2007 to 2009 chart of model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2009 | Tweeter | 1 |
| 2008 | Tweeter | 1 |
| 2007 | Tweeter | 1 |
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 location in the Mercedes-Benz GL320 accommodates a 1-inch speaker opening across the 2007, 2008, and 2009 model years.
- A 1-inch driver diameter is characteristic of tweeter-class speakers, which are physically small to allow precise, controlled high-frequency dispersion from an elevated mounting position.
- The rear roof position places the speaker above the passenger cabin, an orientation that distributes high-frequency sound downward and across the seating area rather than projecting from door or panel surfaces.
- Tweeters reproduce the upper portion of the audible frequency spectrum, generally from approximately 2,000 Hz to 20,000 Hz, handling content such as high harmonics, transient detail, and upper vocal range.
- The small diaphragm of a 1-inch tweeter allows rapid excursion cycles necessary for accurate reproduction of short-wavelength, high-frequency signals.
- Mounting at the rear roof position distances the tweeter from low- and mid-frequency drivers typically located in lower door or kick panel positions, which supports spatial separation between frequency ranges within the cabin.
- An overhead mounting angle affects the directional arrival of high-frequency sound at the listener's ear, as tweeters become increasingly directional at higher frequencies due to their small radiating surface relative to wavelength.
- The Mercedes-Benz GL320 rear roof speaker location is sized specifically for tweeter installation, meaning the 1-inch dimension reflects the physical constraints engineered into the vehicle's headliner or roof structure at that position.
