Additional Notes

The 2016 BMW 535i factory audio system uses a three-way speaker configuration with separate drivers for different frequency ranges in most locations.
Tweeters handling high frequencies are installed at 1 inch across all four positions: center dash, front doors, rear doors, and rear deck lid.
Midrange drivers measure 4 inches and occupy the same four locations as the tweeters, suggesting a component-style setup rather than traditional coaxial speakers.
An 8 inch subwoofer positioned below the seats provides low-frequency output for the system.
Replacing the midrange drivers would likely produce the most noticeable impact on overall sound quality since they handle the majority of vocal and instrumental content.
The uniform 1 inch tweeter size across all locations may limit aftermarket upgrade options compared to more common sizes like 0.75 or 1.25 inches.
Upgrading the subwoofer could enhance bass response, though the below-seat location may constrain installation clearance for larger aftermarket models.
The separation of tweeters and midrange speakers into distinct units typically allows for better frequency response control than combined full-range speakers.
Aftermarket component speaker sets would need to match the specific 4 inch midrange and 1 inch tweeter sizing to fit properly without modification.
