- The 2017 BMW i3 audio system distributes tweeters across three locations, with identical 1-inch units positioned in the center dash, front door panels, and rear door panels, suggesting a focus on high-frequency dispersion throughout the cabin.
- Midrange speakers follow a similar distribution pattern to the tweeters, with 4-inch units installed in the center dash, front door panels, and rear door panels, potentially providing vocal clarity and mid-frequency coverage from multiple points.
- The front 6x9-inch full-range speakers may serve as the primary sound source for lower frequencies and overall volume, as no dedicated woofers or subwoofers are listed in the factory specifications.
- Replacing the 4-inch midrange speakers might offer noticeable improvements in vocal reproduction and instrument separation, as these frequencies typically dominate music content and are distributed across multiple listening positions.
- The 6x9-inch full-range speakers could be prioritized for replacement when seeking enhanced bass response and overall output, as this size typically handles a broader frequency range compared to the smaller dedicated drivers.
- Component speaker systems with separate tweeters and midrange drivers could potentially integrate with the existing multi-location tweeter setup, though the 1-inch size may limit aftermarket options compared to more common tweeter sizes.
- The absence of dedicated low-frequency drivers in the specifications suggests that the 6x9-inch full-range speakers likely handle bass duties, which may limit deep bass extension without adding an aftermarket subwoofer.
- Upgrading all three tweeter locations simultaneously could maintain the factory's intended soundstage width and imaging characteristics while improving high-frequency detail and extension.
