Subaru BRZ Rear Speaker Size
The Subaru BRZ rear location accommodates a 3.5 inch speaker size across all listed model years. Compatible types for the audio system include midrange replacement units. The specifications cover the years 2013 to 2015.
| Year | Type | Size (inch) |
|---|---|---|
| 2015 | Midrange | 3.5 |
| 2014 | Midrange | 3.5 |
| 2013 | Midrange | 3.5 |
Speaker Types
| Type | Description |
|---|---|
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
Additional Notes
- The rear speaker location in the Subaru BRZ accommodates a 3.5 inch driver across the 2013, 2014, and 2015 model years.
- A 3.5 inch speaker occupies a physically compact mounting cutout, which is characteristic of smaller rear deck or interior panel cavities with limited depth and baffle area.
- The small diameter of a 3.5 inch cone reduces the surface area available for air displacement, which constrains low-frequency output and positions the driver's operational range in the upper-mid and midrange bands.
- The Subaru BRZ rear location is specified as compatible exclusively with midrange drivers, meaning woofers and tweeters are not among the supported types for this position.
- Midrange drivers are designed to reproduce frequencies roughly between 300 Hz and 5 kHz, a band that covers vocals, instrument body tones, and much of the harmonic content in recorded audio.
- In a rear cabin position, a midrange driver at 3.5 inches contributes presence and vocal clarity to the rear soundstage without the low-frequency extension that a larger woofer would require a larger enclosure to achieve.
- The compact mounting size of 3.5 inches is consistent with shallow rear panel or side-wall locations found in small sports coupes, where chassis packaging limits available speaker depth.
- A midrange driver in the Subaru BRZ rear location does not extend into the subwoofer or tweeter frequency domains, so the rear installation relies on other system components to cover bass and high-frequency reproduction.
