Additional Notes

  • The 2017 BMW X4 utilizes a multi-way speaker configuration with dedicated frequency-specific drivers distributed across multiple cabin locations.
  • Tweeters handle high-frequency reproduction and are positioned in the center dash, front door panels, rear deck lid, and rear door panels, all measuring 1 inch.
  • Midrange drivers measuring 4 inches occupy the same four locations as the tweeters, creating a component-style setup where high and mid frequencies are separated.
  • This separation of frequencies through dedicated drivers typically allows for clearer vocal reproduction and more detailed high-frequency response compared to full-range coaxial speakers.
  • An 8-inch subwoofer located below the seats provides low-frequency extension for bass reproduction.
  • Replacing the midrange speakers may yield more noticeable sonic changes than tweeter upgrades, as midrange drivers handle the majority of vocal and instrumental content in most music.
  • The 4-inch midrange size represents a relatively compact driver that balances frequency response with space constraints in door and deck installations.
  • Aftermarket component speaker sets would need to match these specific size requirements, with 1-inch dome tweeters and 4-inch midrange drivers being the primary replacement targets.
  • The under-seat subwoofer location suggests a space-efficient design that preserves cargo area while still providing dedicated bass reinforcement.
  • Upgrading speakers in this configuration might benefit from addressing the midrange and tweeter pairs together to maintain tonal balance across the frequency spectrum.
