Tesla 3 Rear Speaker Size
The Tesla 3 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 2017 to 2021 range.
| Year | Type | Size (inch) |
|---|---|---|
| 2021 | Midbass / Full-Range | 6.5 |
| 2020 | Midbass / Full-Range | 6.5 |
| 2019 | Midbass / Full-Range | 6.5 |
| 2018 | Midbass / Full-Range | 6.5 |
| 2017 | 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 Model 3 accommodates a 6.5-inch driver across the 2017 through 2021 model years.
- A 6.5-inch speaker occupies a moderate cone surface area, which produces sufficient piston movement to reproduce lower midrange and upper bass frequencies effectively in a rear cabin position.
- The rear placement of a 6.5-inch driver means the cone radiates sound toward the passenger cabin from behind, a position where low-to-mid frequency reproduction reinforces the overall soundstage without the directional sensitivity that affects higher frequencies.
- The midbass type is a driver designed to handle the frequency band roughly between 80 Hz and 500 Hz, covering the lower midrange and upper bass region where instruments such as bass guitar, kick drum, and male vocals originate their fundamental tones.
- In a rear installation, a midbass driver in the Tesla Model 3 reproduces the low-frequency body of the audio signal, complementing front-stage drivers that handle higher frequencies.
- The full-range type is a driver engineered to reproduce a wide span of frequencies, typically from around 60 Hz up to 20 kHz, within a single cone and speaker assembly.
- When a full-range driver is installed in the Tesla Model 3 rear location, the 6.5-inch cone handles both the bass and treble content of the signal, often with the assistance of a small whizzer cone or treated surround to extend high-frequency response.
- The 6.5-inch mounting diameter requires a specific baffle opening and depth clearance in the rear panel, and the Tesla Model 3 rear speaker location must accommodate the basket depth of whichever driver type is installed.
- Midbass drivers are typically built with stiffer suspensions and heavier voice coils relative to full-range drivers of the same diameter, which affects the mounting depth requirement within the rear cavity of the Tesla Model 3.
- Full-range drivers at 6.5 inches balance cone mass against compliance to achieve a broader frequency response, a design tradeoff that influences sensitivity and power handling at the rear speaker position.
