BMW i3 Center Dash Speaker Size
The BMW i3 center dash accommodates a 1 inch speaker size and 4 inch units. Compatible speaker types for the location include tweeters and midrange units. The specifications cover the 2014 to 2017 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Tweeter | 1 |
| 2017 | Midrange | 4 |
| 2016 | Tweeter | 1 |
| 2016 | Midrange | 4 |
| 2015 | Tweeter | 1 |
| 2015 | Midrange | 4 |
| 2014 | Tweeter | 1 |
| 2014 | Midrange | 4 |
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. |
| 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 center dash location in the BMW i3 accommodates 2 distinct speaker sizes across all listed model years: 1 inch and 4 inch.
- A center dash placement positions speakers along the vehicle's lateral midpoint, which is acoustically significant for stereo imaging and soundstage centering relative to the listening position.
- The 1-inch drivers at the center dash position are designated for tweeter use, a speaker type optimized for high-frequency reproduction, generally operating in ranges above 2,000 Hz.
- Tweeters in a center dash location direct high-frequency content toward the cabin's listening area, where treble frequencies-being highly directional by nature-benefit from a forward-facing, centrally positioned source.
- The BMW i3 center dash tweeter and midrange pairing across the 2014-2017 model years indicates the location supports a 2-driver configuration per installation point.
- The 4-inch drivers at the center dash are designated for midrange use, a speaker type handling frequencies generally between approximately 300 Hz and 5,000 Hz, covering much of the vocal and instrumental presence range.
- A 4-inch midrange driver is a relatively compact diameter, which suits the spatial constraints typical of a center dash cavity while still reproducing mid-frequency content with adequate cone area.
- Midrange speakers placed in a center dash location reproduce the frequency band most associated with speech intelligibility and vocal clarity, which aligns acoustically with the forward-centered position relative to front-seat occupants.
- The 1-inch tweeter size is a standard dome tweeter dimension; at the center dash, the small physical footprint allows integration into shallow or narrow dashboard cavities without requiring deep rear clearance.
- The consistent pairing of a 1-inch tweeter and a 4-inch midrange across all 4 listed model years indicates dimensional and type compatibility is stable throughout the BMW i3's 2014-2017 production span for the center dash location.
