Lexus NX300h Rear Door Panel Speaker Size
The Lexus NX300h rear door panel accommodates a 6.5 inch speaker size. Compatible types for the location include midbass and full-range units. These specifications cover the 2015 model year.
| Year | Type | Size (inch) |
|---|---|---|
| 2015 | 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 Lexus NX300h places speakers within the lower portion of the door cavity, a position that is acoustically suited to reproducing low-to-mid frequencies directed toward the cabin floor and lower passenger space.
- Door panel mounting in this vehicle positions the speaker baffle flush against an inner door skin, meaning the speaker cone fires laterally into the cabin rather than from above or below, affecting the dispersion angle relative to seated passengers.
- A 6.5-inch driver occupies a middle ground in cone surface area, producing enough pistonic displacement to handle bass-frequency output while remaining compact enough to fit within the spatial constraints of a rear door panel cavity.
- The rear door panel location is physically separated from front-stage drivers, which means a 6.5-inch speaker installed here contributes to rear-fill coverage and spatial depth across the cabin.
- In a rear door panel, a 6.5-inch driver typically handles a frequency range spanning approximately 60 Hz to 5,000 Hz, depending on the crossover configuration and cabinet volume formed by the door cavity itself.
- The door cavity behind the speaker mounting point acts as an acoustic chamber; the volume and dampening characteristics of the Lexus NX300h rear door interior directly influence the low-frequency extension available from a 6.5-inch installation.
- A midbass speaker type is designed to operate across the lower-midrange and upper-bass frequencies, generally rolling off before the high-frequency range, making rear door panel placement appropriate for a driver focused on body and warmth rather than treble detail.
- A full-range speaker type covers bass, midrange, and treble frequencies within a single driver, and in a rear door panel location, the high-frequency dispersion from such a driver is naturally limited by the off-axis angle relative to the listener's ear level.
- The 2015 Lexus NX300h rear door panel is the listed compatible vehicle year and location for the NX300h, and compatibility at this position requires the replacement driver to conform to the original 6.5-inch cutout diameter and mounting bolt pattern.
- Rear door panel installations are subject to moisture and vibration exposure from window mechanisms and road noise, which are environmental factors relevant to material selection in both midbass and full-range driver types placed at this location.
