Lexus LX470 Rear Door Panel Speaker Size
The Lexus LX470 rear door panel accommodates 6.5 inch speakers and a 6.75 inch speaker size across the model's production span. Compatible speaker types for all years include midbass and full-range units. These specifications cover the 1998 to 2007 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2007 | Midbass / Full-Range | 6.75 |
| 2006 | Midbass / Full-Range | 6.5 |
| 2005 | Midbass / Full-Range | 6.5 |
| 2004 | Midbass / Full-Range | 6.5 |
| 2003 | Midbass / Full-Range | 6.5 |
| 2002 | Midbass / Full-Range | 6.5 |
| 2001 | Midbass / Full-Range | 6.5 |
| 2000 | Midbass / Full-Range | 6.5 |
| 1999 | Midbass / Full-Range | 6.5 |
| 1998 | 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 on the Lexus LX470 places speakers within the lower portion of the passenger doors, positioning the drivers closer to floor level than ear level for seated occupants.
- Door panel mounting typically involves a recessed basket fit against sheet metal, where the door cavity itself acts as an enclosure that influences low-frequency output and cone excursion behavior.
- The 6.5 inch diameter specified for the 1998 through 2006 model years fits a mounting opening sized to accommodate a driver with a cone area suited to reproducing lower midrange and upper bass frequencies from within the door panel cavity.
- The 6.75 inch diameter specified for the 2007 Lexus LX470 rear door panel represents a slightly larger cone area than 6.5 inch drivers, which translates to marginally greater air displacement and an incremental extension in low-frequency capability at the same mounting depth.
- A 6.75 inch driver requires a mounting cutout and depth clearance distinct from a 6.5 inch driver, meaning speaker selection for the 2007 model year must account for the larger diameter when fitting within the rear door panel cavity.
- Midbass drivers are designed to reproduce the frequency range roughly between 80 Hz and 500 Hz, covering the lower midrange and upper bass bands that include fundamental tones of vocals, instruments, and lower harmonics.
- In a rear door panel location, midbass drivers reinforce the low-frequency foundation of the audio system, supplementing subwoofer or woofer output and contributing body and warmth to the overall soundstage from the rear of the cabin.
- Full-range drivers are designed to reproduce a wider frequency span, generally from around 60 Hz up to 20 kHz within a single driver, handling bass, midrange, and treble from one point of origin.
- A full-range driver mounted in the rear door panel of the LX470 would emit high-frequency content from a low, off-axis position relative to seated occupants, which affects treble directionality and imaging differently than a dedicated tweeter mounted at ear height.
- Both compatible types listed across all model years share the same mounting diameter for a given year, meaning the physical installation space accommodates either a midbass or full-range driver without structural modification to the door panel opening.
