Lexus GX470 Rear Door Panel Speaker Size
The Lexus GX470 rear door panel accommodates a 6.5 inch speaker size in that location. Compatible types for the audio system include midbass and full-range replacement units. These specifications cover the 2003 to 2009 model chart 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 locations in the Lexus GX470 accommodate 6.5 inch speakers across all listed model years.
- Door panel speaker mounting positions place drivers within the lower portion of the door cavity, where the cone radiates sound upward and inward toward the cabin at an angle determined by the door's interior contour.
- A 6.5 inch driver carries a cone surface area sufficient to move the air volume needed for mid-frequency reproduction, while the door cavity behind the mounting point acts as an enclosure that influences low-frequency extension and resonance behavior.
- The rear door panel position places speakers at a greater distance from the front listening position, which affects time alignment and the contribution of rear speakers to the overall stereo or surround soundstage.
- Midbass drivers are designed to handle the frequency range roughly between 80 Hz and 500 Hz, prioritizing cone excursion and low-frequency output over high-frequency extension, making the Lexus GX470 rear door panel location suitable for reinforcing lower midrange and bass content in the cabin.
- Full-range drivers are engineered to reproduce a broader spectrum, typically from around 60 Hz up to 20 kHz, within a single driver, which suits door panel locations where a single mounting cutout must handle the full audio signal without a supplementary tweeter at the same position.
- At 6.5 inches, the driver diameter represents a balance between low-frequency displacement and the physical constraints of a door panel mounting cavity, where depth clearance behind the mounting surface and the interior door structure limit how large a basket and magnet assembly can fit.
- The rear door panel mounting surface in an SUV body style like the GX470 is typically a flat or slightly curved section of the inner door trim, and speaker depth, including the magnet and basket, must not contact the door's inner metal skin when the window glass is in the lowered position.
- Because rear door panel speakers in vehicles with second or third-row seating are positioned closer to rear passengers, the 6.5 inch drivers in the GX470 rear doors contribute more directly to the listening experience of occupants in those seating rows.
- The compatibility of both midbass and full-range types at the rear door panel location indicates the mounting cutout and depth clearance can physically accommodate either driver category at the 6.5 inch diameter.
