Honda Passport Rear Door Panel Speaker Size
The Honda Passport rear door panel accommodates a 6.5 inch speaker size and 4x6 inch speakers, with each location supporting the respective size across the applicable model years. Compatible types include midbass and full-range units, depending on the specific size in use. These specifications cover the 1996 to 2002 model range.
| Year | Type | Size (inch) |
|---|---|---|
| 2002 | Midbass / Full-Range | 6.5 |
| 2001 | Midbass / Full-Range | 6.5 |
| 2000 | Midbass / Full-Range | 6.5 |
| 1997 | Full-Range | 4x6 |
| 1996 | Full-Range | 4x6 |
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 places speakers within the lower portion of the cabin doors, positioning the drivers closer to occupant leg level than to ear level.
- A 6.5 inch driver in the rear door panel of the Honda Passport occupies a mounting cutout that typically requires a depth clearance compatible with the door's inner cavity, where limited space behind the mounting surface is a common constraint.
- The 4x6 inch oval format fits a narrower or shallower mounting recess than a round 6.5 inch driver, reflecting a door panel cavity geometry present in the 1996 and 1997 models that differs from the later round cutout configuration.
- A 6.5 inch speaker, as a round driver, produces greater cone surface area than a 4x6 inch oval, which corresponds to stronger low-midrange output and deeper bass extension within the rear door panel environment.
- The midbass type, listed as compatible with the 6.5 inch position, is a driver optimized for the roughly 80 Hz to 500 Hz frequency band, reinforcing the lower musical registers that benefit from rear door placement near the vehicle floor.
- A full-range speaker covers a wider frequency span than a midbass driver, typically reproducing frequencies from approximately 60 Hz up to 20 kHz through a single cone, making a single driver sufficient for the rear door panel without a separate tweeter.
- The 4x6 inch oval format, listed only as full-range compatible, reflects the geometry's general limitation in low-frequency excursion, as the shorter cone axis reduces the driver's ability to move the air volume needed for dedicated midbass reproduction.
- Rear door panel speakers operate in a partially enclosed acoustic environment formed by the door's inner structure, which can act as an informal enclosure and influence bass resonance characteristics of any driver mounted there.
- The transition between the 4x6 inch oval mounting dimensions in 1996-1997 and the 6.5 inch round mounting dimensions in 2000-2002 indicates a change in the rear door panel cavity design across those model years of the Honda Passport.
- Because the rear door panel position is physically separated from the front soundstage, midbass drivers placed there contribute low-frequency fill without requiring the directional precision that higher-frequency drivers demand.
