Mercedes-Benz GL320 Cargo Area Speaker Size
The Mercedes-Benz GL320 cargo area accommodates an 8 inch speaker size across all listed model years. Compatible types for the cargo area include subwoofer units suited for low-frequency audio reproduction within the system. These specifications cover the 2007 to 2009 model range.
| Year | Type | Size (inch) |
|---|---|---|
| 2009 | Subwoofer | 8 |
| 2008 | Subwoofer | 8 |
| 2007 | Subwoofer | 8 |
Speaker Types
| Type | Description |
|---|---|
| Subwoofer | A large driver for the lowest bass notes, typically from about 20 Hz to 120 Hz. It is usually installed in a separate enclosure and works alongside the other speakers. |
Additional Notes
- The cargo area of the Mercedes-Benz GL320 accommodates an 8-inch speaker cutout across the 2007, 2008, and 2009 model years.
- An 8-inch driver occupies a mid-to-large cone surface area, which allows for greater air displacement compared to smaller cone sizes, a physical property directly relevant to low-frequency reproduction in an enclosed cargo space.
- The cargo area location positions the speaker within a partially enclosed rear volume, which functions acoustically as a loading chamber that interacts with a subwoofer's bass output and rear-wave propagation.
- A subwoofer is a driver designed to reproduce the lowest audible frequencies, typically operating within a range of approximately 20 Hz to 200 Hz, well below the range handled by full-range drivers or tweeters.
- Subwoofers require a defined enclosure volume to perform correctly, and the cargo area of the Mercedes-Benz GL320 presents a bounded rear cavity that can serve as or interface with such an enclosure.
- The 8-inch cone diameter on a subwoofer in a cargo area context allows the driver to move enough air to produce low-frequency pressure waves perceptible throughout the cabin without requiring the larger footprint of a 10-inch or 12-inch unit.
- Subwoofers are non-directional at very low frequencies because wavelengths at those frequencies are significantly longer than the physical dimensions of the driver, meaning placement in the rear cargo zone does not critically affect perceived bass localization within the cabin.
- The mounting depth required by an 8-inch subwoofer is generally greater than that of smaller full-range drivers, making the cargo area's typically deeper panel cavities or floor structures more suitable for such a driver than shallower door or dash locations.
