BMW X1 Center Dash Speaker Size
The BMW X1 center dash location accommodates a 1 inch speaker size and 4 inch speakers. Compatible types for the audio system include tweeter and midrange replacement units. These specifications cover the 2016 to 2018 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Tweeter | 1 |
| 2018 | Midrange | 4 |
| 2017 | Tweeter | 1 |
| 2017 | Midrange | 4 |
| 2016 | Tweeter | 1 |
| 2016 | 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 X1 accommodates 2 distinct speaker sizes simultaneously, indicating a multi-driver configuration within a single mounting zone.
- A 1-inch driver mounted at the center dash occupies a compact footprint, consistent with shallow-depth cavities typical of dashboard speaker housings where physical space is constrained by instrument cluster components and HVAC ducting.
- The center dash position places a 1-inch tweeter near the horizontal center of the windshield base, a location that contributes to high-frequency imaging across the front soundstage due to proximity to ear level and the reflective surface of the windshield.
- Tweeters reproduce high-frequency content, generally from around 2,000 Hz upward, and a 1-inch dome or cone driver in the center dash serves to anchor treble detail at a central point between the left and right channels.
- The 4-inch driver at the center dash handles midrange frequencies, typically spanning approximately 300 Hz to 5,000 Hz, covering vocal intelligibility and a significant portion of instrumental harmonic content.
- A 4-inch midrange speaker in a dash-mounted location operates within a relatively enclosed baffle formed by the dashboard structure, which influences rear-wave management and resonance behavior compared to door or rear deck installations.
- The BMW X1 center dash configuration with a 4-inch midrange and 1-inch tweeter suggests a two-way speaker arrangement at the center position, where each driver covers a dedicated frequency band rather than a single full-range driver handling the entire spectrum.
- The 4-inch cone diameter produces a relatively directional dispersion pattern at upper midrange frequencies, and the center dash placement projects audio toward the front cabin occupants along a fairly direct path.
- The 1-inch tweeter's small diaphragm mass enables rapid pistonic movement at high frequencies, a property particularly relevant at the center dash where acoustic reflections off the windshield can reinforce high-frequency presence in the front listening area.
- The specification applies uniformly across the 2016, 2017, and 2018 BMW X1, meaning the physical mounting dimensions and compatible speaker types remain consistent across all 3 listed model years.
