Hummer H2 Rear Door Panel Speaker Size
The Hummer H2 rear door panel accommodates a 6.5 inch speaker size across all listed model years. Compatible audio types for the location include midbass and full-range replacement units. The specifications cover the 2003 to 2009 system range.
| Year | Type | Size (inch) |
|---|---|---|
| 2009 | Midbass / Full-Range | 6.5 |
| 2008 | Midbass / Full-Range | 6.5 |
| 2007 | Midbass / Full-Range | 6.5 |
| 2006 | Midbass / Full-Range | 6.5 |
| 2005 | Midbass / Full-Range | 6.5 |
| 2004 | Midbass / Full-Range | 6.5 |
| 2003 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| Midbass | A driver tuned for upper bass and lower midrange, roughly from 80 Hz to 500 Hz. It has longer cone travel than a full-range unit, which supports stronger bass in doors and panels. |
| Full-Range | A single driver that reproduces bass through treble without a separate crossover network. It is the simplest replacement option and is common in factory audio systems. |
Additional Notes
- The rear door panel location in the Hummer H2 positions speakers within the lower portion of the door, mounting them against an interior panel surface that faces inward toward the cabin.
- Door panel mounting places the speaker cone at roughly seat or below-seat height, which affects how low-frequency and midrange sound waves travel through the cabin space before reaching passengers.
- The mounting cavity within a door panel is enclosed on the exterior side by the door shell, which can act as an acoustic boundary that influences bass reinforcement depending on available internal air volume.
- A 6.5 inch driver occupies a mid-sized cone area that supports meaningful low-midrange output, typically covering frequencies from approximately 60 Hz up through 5 kHz depending on driver design and crossover configuration.
- The cone diameter of 6.5 inches gives the driver enough surface area to move sufficient air for midbass reproduction at the rear door panel location, where low-frequency fill for rear-seat passengers is a primary acoustic function.
- The Hummer H2 rear door panel accommodates a 6.5 inch speaker, a dimension that determines the cutout diameter and the maximum basket width a replacement or upgrade driver must not exceed for a flush fit.
- A midbass driver is designed to reproduce the lower midrange and upper bass frequencies, generally from around 80 Hz to 500 Hz, functioning without a tweeter and typically used with a high-pass filter to protect the cone from deep bass distortion.
- A full-range driver is constructed to reproduce a wide frequency band from bass through treble from a single cone, sometimes incorporating a whizzer cone or similar element to extend high-frequency response at the rear door panel position.
- At the rear door panel location, a full-range driver handles the entire audible spectrum assigned to the rear channel, making the choice relevant when no separate rear tweeter is present in the vehicle.
- The midbass type at the rear door panel location is suited to systems where a separate tweeter handles high-frequency reproduction elsewhere in the rear cabin, dividing acoustic responsibilities between drivers by frequency range.
