Isuzu i-370 Rear Door Panel Speaker Size
The Isuzu i-370 rear door panel accommodates a 6.5 inch speaker size. Compatible types for the location include midbass and full-range audio units. The specifications cover the 2007 to 2008 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2008 | Midbass / Full-Range | 6.5 |
| 2007 | 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 Isuzu i-370 accommodates 6.5 inch speakers across the 2007 and 2008 model years.
- A 6.5 inch speaker diameter occupies a mid-sized mounting footprint, which in a rear door panel typically means the mounting depth must clear internal door hardware, window mechanisms, and structural bracing behind the panel surface.
- Door panel installations are generally flush-mounted or shallow-mounted positions, where the speaker basket projects into the door cavity, making mounting depth a relevant spatial consideration alongside the diameter.
- The 6.5 inch cone surface area in a rear door panel position places the driver at a distance from front-seat listeners, which affects the directional contribution of mid and upper frequencies reaching the cabin.
- Midbass drivers in a 6.5 inch format are suited to reproduce frequencies roughly in the 60 Hz to 500 Hz range, concentrating on the lower midrange and upper bass frequencies that add body and warmth to audio reproduction at the rear door position.
- Full-range speakers in a 6.5 inch configuration cover a broader spectrum, typically from around 60 Hz up to several kilohertz, often incorporating a small tweeter element or whizzer cone to extend high-frequency response from a single driver.
- In a rear door panel, a full-range 6.5 inch speaker handles bass, midrange, and partial treble reproduction from a single mounting point, without requiring a separate tweeter installation in the same location.
- A midbass 6.5 inch driver at the rear door panel focuses on low-to-mid frequency support, and in a system context, a separate tweeter mounted elsewhere in the rear cabin would handle upper frequencies not reproduced by the midbass unit.
- The Isuzu i-370 rear door panel, with a 6.5 inch cutout specification, defines the maximum speaker diameter that fits the factory mounting ring and grille dimensions for both compatible speaker types listed.
