Additional Notes

The 2015 BMW ActiveHybrid 7 audio system contains multiple speaker locations distributed throughout the cabin, with tweeters and midrange drivers working in combination to reproduce different frequency ranges.
Tweeters handling higher frequencies are positioned in the center dash, front door panels, rear door panels, and rear deck lid, each measuring 1 inch in size.
Midrange speakers responsible for mid-frequency reproduction are installed in matching locations to the tweeters, specifically the center dash, both front door panels, both rear door panels, and the rear deck lid, with each measuring 4 inches.
Low-frequency reproduction is handled by an 8-inch subwoofer located below the seats, which typically focuses on bass output.
The pairing of 1-inch tweeters with 4-inch midrange drivers in the same general locations suggests a component-style speaker arrangement rather than full-range coaxial designs.
Replacement speakers would need to match the specific sizes at each location, with aftermarket options requiring compatibility with the 1-inch tweeter, 4-inch midrange, and 8-inch subwoofer specifications.
The front door panels may be considered a priority replacement location since they house both tweeter and midrange components that contribute significantly to the soundstage heard by front occupants.
Aftermarket component speaker sets designed for these size specifications could potentially offer improved material construction and power handling compared to factory-installed units.
