Hummer H2 Rear Speaker Size
The Hummer H2 rear location accommodates an 8 inch speaker size, supporting 8 inch units across all listed model years. Compatible audio system replacement types for the rear include subwoofer configurations. The specifications chart covers the 2008 to 2009 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2009 | Subwoofer | 8 |
| 2008 | 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 rear speaker location in the Hummer H2 is dimensioned to accommodate an 8-inch driver across the 2008 and 2009 model years.
- An 8-inch speaker occupies a mounting cavity requiring sufficient depth and baffle area to seat a driver of that diameter, meaning the rear enclosure or panel in the H2 is engineered with enough physical volume to house a driver of this class.
- The 8-inch diameter places the driver in a mid-to-large size range, producing a cone area large enough to move substantial air volume, which is directly relevant to low-frequency reproduction in the rear of the cabin.
- The rear location of a vehicle typically benefits from larger drivers due to the greater available mounting depth and panel space found behind the rear seating area, conditions consistent with an 8-inch fitment.
- The sole compatible type listed for the Hummer H2 rear location is the subwoofer, a driver designed specifically for low-frequency reproduction, generally operating in a range below approximately 80 to 200 Hz depending on crossover configuration.
- A subwoofer at the rear of the H2 cabin takes advantage of the acoustic properties of low frequencies, which are largely omnidirectional at typical subwoofer operating ranges, making the rear placement acoustically viable without significant localization by occupants.
- An 8-inch subwoofer in a rear vehicle location produces bass frequencies through high cone excursion rather than high-frequency transient detail, requiring adequate mounting depth behind the baffle to allow full forward and rearward cone travel without mechanical obstruction.
- Subwoofers are passive radiators of low-frequency energy and typically require an enclosure or sealed mounting surface to control rear wave cancellation, meaning the rear panel or enclosure design of the H2 is a relevant factor in the acoustic output of the specified driver.
