Lexus LX570 Rear Door Panel Speaker Size
The Lexus LX570 rear door panel accommodates a 6.75 inch speaker size and 4 inch speakers. Compatible types across both locations include midbass, full-range, and midrange units. These specifications cover the 2008 to 2015 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2015 | Midbass / Full-Range | 6.75 |
| 2015 | Midrange | 4 |
| 2014 | Midbass / Full-Range | 6.75 |
| 2014 | Midrange | 4 |
| 2013 | Midbass / Full-Range | 6.75 |
| 2013 | Midrange | 4 |
| 2011 | Midbass / Full-Range | 6.75 |
| 2011 | Midrange | 4 |
| 2010 | Midbass / Full-Range | 6.75 |
| 2010 | Midrange | 4 |
| 2009 | Midbass / Full-Range | 6.75 |
| 2009 | Midrange | 4 |
| 2008 | Midbass / Full-Range | 6.75 |
| 2008 | Midrange | 4 |
Speaker Types
| Type | Description |
|---|---|
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
| 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 LX570 houses 2 distinct speaker positions per door, each designated for a different driver size and acoustic role.
- Door panel mounting positions are typically shallow-depth enclosures integrated into the inner door skin, meaning cone excursion and magnet depth are constrained by the available airspace behind the mounting surface.
- The 6.75 inch driver position in the rear door panel accommodates a speaker diameter that produces sufficient cone surface area to move the air volume needed for lower-frequency reproduction in a door-cavity environment.
- A 6.75 inch driver is compatible with midbass and full-range types in the Lexus LX570 rear door panel, covering the lower-midrange and bass frequencies typically spanning from approximately 60 Hz to 5 kHz depending on crossover configuration.
- A midbass driver in the 6.75 inch rear door position is a dedicated low-to-mid frequency transducer, designed to handle the portion of the audio spectrum below the midrange without extending to the high-frequency range.
- A full-range driver in the 6.75 inch rear door position reproduces a wide frequency band from a single cone, relying on the driver's internal mechanical design rather than an external crossover to manage frequency extension.
- The 4 inch driver position in the rear door panel of the Lexus LX570 accommodates a smaller cone diameter, which results in reduced low-frequency output capability but improved dispersion and accuracy in the upper-midrange band.
- The 4 inch position is designated exclusively for midrange type speakers, placing acoustic responsibility on the frequency band approximately between 500 Hz and 5 kHz, which carries much of the tonal definition of vocals and instruments.
- A midrange driver in a door panel location benefits from the relatively close proximity to passengers in rear seating rows, where directional midrange frequencies are more easily projected toward the listening area.
- The rear door panel placement positions both the 6.75 inch and 4 inch drivers along a vertical plane within the door structure, which affects the horizontal and vertical dispersion angles relative to rear seat occupants.
- Door panel speaker positions are acoustically influenced by the internal door cavity volume, which acts as an uncontrolled rear chamber and can affect the low-frequency response of the 6.75 inch driver in both midbass and full-range configurations.
- The dual-size configuration across all model years in the specifications places a larger driver for low-to-mid frequency duties and a smaller driver for upper-midrange duties within the same rear door panel mounting structure.
