Additional Notes

The 2013 BMW ActiveHybrid 5 audio system incorporates a three-way speaker configuration with dedicated tweeters, midrange drivers, and subwoofers distributed across multiple locations throughout the cabin.
Tweeters measuring 1 inch are positioned in the center dash, front door panels, rear deck lid, and rear door panels to handle high-frequency reproduction.
Midrange speakers sized at 4 inches occupy the same locations as the tweeters, creating a multi-speaker arrangement in each zone for broader frequency coverage.
An 8-inch subwoofer located below the seats handles low-frequency output in the factory configuration.
The separation of frequencies across dedicated speaker types may allow for more controlled sound staging compared to full-range speaker designs.
Aftermarket upgrades would need to account for the three-way system architecture when selecting replacement components to maintain the intended frequency distribution.
The 1-inch tweeter size represents a common format in automotive audio systems, though installation depth and mounting requirements would need verification during replacement.
The 4-inch midrange speakers likely handle the critical vocal and instrumental frequencies that dominate most music content.
Subwoofer placement below the seats suggests an effort to maximize cabin space while still providing bass reinforcement.
Replacing speakers in a multi-way factory system typically requires attention to impedance matching and sensitivity ratings to avoid imbalances between the different drivers.
