Land Rover Defender 110 Rear Door Panel Speaker Size
The Land Rover Defender 110 rear door panel accommodates a 6.5 inch speaker size. Compatible types for the location include midbass and full-range audio units. These specifications cover the 1993 system year.
| Year | Type | Size (inch) |
|---|---|---|
| 1993 | 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 Land Rover Defender 110 positions speakers within a door cavity, where the enclosure depth and baffle surface area are determined by the door's structural frame and inner skin dimensions.
- Door panel mounting typically places the speaker flush or near-flush against the interior trim, with the driver facing into the cabin to project sound toward the passenger area.
- A 6.5 inch driver occupies a mid-sized footprint on the door baffle, requiring a cutout diameter and mounting depth compatible with the Defender 110's rear door panel cavity.
- The 6.5 inch cone diameter produces a relatively broad radiating surface that supports low-to-mid frequency reproduction, covering roughly 60 Hz to 5 kHz depending on driver construction.
- In a rear door panel location, a 6.5 inch driver benefits from the door cavity acting as a partial enclosure, which can reinforce lower frequency output compared to a fully open-back mounting surface.
- The midbass type is designed to handle the lower portion of the midrange and upper bass frequencies, typically operating between approximately 80 Hz and 500 Hz, contributing to the weight and body of vocal and instrumental content.
- A full-range type is built to reproduce a wider frequency spectrum from a single driver, spanning roughly 60 Hz to 20 kHz, making the 1993 Land Rover Defender 110 rear door panel a location where a single driver can serve the entire audible range without additional components.
- Midbass drivers in a rear door panel are commonly crossed over to a tweeter mounted elsewhere in the cabin, since the rear door position and driver size are not optimized for high-frequency dispersion above approximately 3 kHz to 5 kHz.
- The rear door panel on the Defender 110 is a lateral mounting surface, meaning the speaker radiates sound horizontally across the cabin rather than from a forward-facing dashboard or floor position.
- Compatibility with both midbass and full-range types at the 6.5 inch size indicates the mounting hole pattern and available depth in the rear door panel can physically accommodate drivers built for either acoustic role.
