| 2018 | Midrange | 4 |
| 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 M6 Gran Coupe sits at the horizontal plane of the instrument panel, positioning speakers close to windshield glass and at a relatively central point between the driver and front passenger.
- A center dash mount places speakers at a shallow depth with limited enclosure volume behind the mounting surface, which constrains the low-frequency extension available to any driver installed there.
- The 1-inch driver size found in the center dash of the BMW M6 Gran Coupe accommodates a tweeter, a driver type designed to reproduce high frequencies typically spanning from around 2,000 Hz up to 20,000 Hz or beyond.
- Tweeters at the 1-inch diameter operate with a small diaphragm that moves air rapidly at high frequencies while requiring minimal excursion, making the shallow depth of a center dash cavity a compatible mechanical environment.
- The center dash position places the 1-inch tweeter near the base of the windshield, a location that can use the glass surface as a reflective boundary to help disperse high-frequency energy across the cabin.
- The 4-inch driver size at the center dash location supports a midrange type, which handles the middle portion of the audible spectrum, generally from approximately 300 Hz to 5,000 Hz, covering fundamental vocal and instrumental frequencies.
- A 4-inch midrange cone is small enough to maintain directional control across its operating frequency band while fitting within the spatial constraints of a center dash opening.
- The center dash placement of a 4-inch midrange positions the source of vocal and mid-frequency content at a central point on the soundstage, equidistant from both front seating positions.
- At 4 inches, the midrange driver has a relatively modest diaphragm area, which limits its output in the lower midrange frequencies but reduces the cone breakup and distortion concerns that arise in larger drivers at higher frequencies.
- The pairing of a 1-inch tweeter and a 4-inch midrange at the same center dash location indicates a two-driver configuration at that position, requiring crossover filtering to divide the frequency spectrum between the 2 drivers.
