Land Rover LR4 Rear Door Panel Speaker Size
The Land Rover LR4 rear door panel accommodates 6.5 inch speakers and supports a 1 inch speaker size in the same location. Compatible types across both size categories include midbass, full-range, and tweeter audio units. These specifications cover a range of years from 2010 to 2016.
| Year | Type | Size (inch) |
|---|---|---|
| 2016 | Midbass / Full-Range | 6.5 |
| 2016 | Tweeter | 1 |
| 2015 | Midbass / Full-Range | 6.5 |
| 2015 | Tweeter | 1 |
| 2014 | Midbass / Full-Range | 6.5 |
| 2014 | Tweeter | 1 |
| 2013 | Midbass / Full-Range | 6.5 |
| 2013 | Tweeter | 1 |
| 2012 | Midbass / Full-Range | 6.5 |
| 2012 | Tweeter | 1 |
| 2011 | Midbass / Full-Range | 6.5 |
| 2011 | Tweeter | 1 |
| 2010 | Midbass / Full-Range | 6.5 |
| 2010 | Tweeter | 1 |
Speaker Types
| Type | Description |
|---|---|
| Tweeter | A small driver built for high frequencies, typically from about 2,000 Hz to 20,000 Hz. It adds treble detail and clarity and is usually mounted near ear level or aimed at the listener. |
| 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 Land Rover LR4 rear door panel accommodates a 2-speaker configuration per door, with a 6.5 inch driver and a 1 inch driver occupying separate mounting positions within the panel.
- Rear door panel locations are typically recessed into the inner door skin, meaning available depth and baffle area directly constrain the physical dimensions of compatible speaker drivers.
- A 6.5 inch speaker cone diameter corresponds to a mounting cutout in the range of approximately 5.75 to 6 inches, requiring sufficient door cavity depth to accommodate the basket and magnet assembly without contacting the outer door structure.
- The 6.5 inch position in the Land Rover LR4 rear door panel is designated for midbass or full-range drivers, both of which rely on the larger cone area to move enough air for effective low-to-mid frequency reproduction in the 80 Hz to 5 kHz range.
- A midbass driver in the rear door panel focuses on the lower portion of the midrange and upper bass frequencies, working in conjunction with a dedicated subwoofer in systems where low-frequency extension is handled separately.
- A full-range driver at the 6.5 inch rear door position covers a broader frequency span without requiring a crossover partner, operating across bass, midrange, and portions of the upper midrange from a single cone.
- The 1 inch driver position in the rear door panel is designated exclusively for tweeters, which reproduce high-frequency content typically above 2 kHz to 3 kHz, where smaller diaphragm sizes maintain controlled directional dispersion.
- A 1 inch tweeter placed within a door panel faces directional constraints, as high frequencies above approximately 8 kHz become increasingly directional and the listening axis relative to rear-seat passengers influences perceived treble balance.
- The physical separation between the 6.5 inch and 1 inch mounting locations within the same door panel creates a spatial offset between low-mid and high-frequency sources, a factor relevant to crossover alignment in active or passive systems.
- The rear door panel location positions drivers closer to the floor level compared to front door panels, which affects the vertical angle of sound projection toward rear-seat occupants and the degree of high-frequency attenuation over distance.
- The consistent dual-driver configuration across the 2010 through 2016 model years indicates a stable mounting geometry throughout the LR4 generation, with the same 6.5 inch and 1 inch cutout dimensions applying across all listed years.
