Tesla Roadster Rear Speaker Size
The Tesla Roadster rear location accommodates a 6.5 inch speaker size across all listed model years. Compatible types for the audio system include midbass and full-range replacement units. These specifications cover the range of 2008 to 2011.
| Year | Type | Size (inch) |
|---|---|---|
| 2011 | Midbass / Full-Range | 6.5 |
| 2010 | Midbass / Full-Range | 6.5 |
| 2009 | Midbass / Full-Range | 6.5 |
| 2008 | 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 speaker location in the Tesla Roadster accepts a 6.5 inch driver across all model years listed in the specifications.
- A 6.5 inch driver occupies a mid-sized mounting footprint, requiring a cutout diameter and depth clearance consistent with that cone size in the rear enclosure or panel cavity.
- The rear mounting position in the Tesla Roadster is a dedicated spatial zone separate from any front stage, meaning the 6.5 inch drivers installed there contribute to the rear portion of the vehicle's soundstage.
- A 6.5 inch driver in a rear location produces sufficient cone surface area to move air effectively in the low-to-mid frequency range, typically covering approximately 60 Hz to 5 kHz depending on driver design.
- The midbass type listed as compatible for the Tesla Roadster rear location is a driver optimized for the lower portion of the midrange and upper bass frequencies, roughly 80 Hz to 500 Hz, and is not intended to reproduce the full audible spectrum independently.
- A midbass driver in a rear position functions as part of a multi-driver system, typically receiving a filtered signal that excludes high frequencies and very low bass.
- The full-range type listed as compatible is a driver designed to reproduce a broad portion of the audible spectrum from a single cone, covering bass, midrange, and upper frequencies without requiring a crossover network.
- A full-range 6.5 inch driver installed in the rear position can operate as a standalone reproducer of most audible content, though cone size places physical limits on extreme high-frequency dispersion.
- The rear location's compatibility with both midbass and full-range types indicates the mounting cavity accommodates drivers with varying voice coil depths and basket profiles within the 6.5 inch standard.
- In a rear position, a 6.5 inch full-range driver tends to contribute to ambient or fill sound rather than precise stereo imaging, due to the listening distance and angle relative to the occupants.
