- The 2017 BMW 650i Gran Coupe features a multi-driver speaker system with dedicated tweeters, midrange drivers, and a subwoofer positioned throughout the cabin.
- Tweeters in this configuration measure 1 inch and are located in four distinct positions: center dash, front door panels, rear deck lid, and rear door panels.
- Midrange drivers measure 4 inches and occupy the same locations as the tweeters, suggesting a component-style setup with separate frequency-specific drivers.
- The presence of dedicated tweeters and midrange speakers in multiple locations indicates a factory audio system designed with frequency separation in mind.
- An 8-inch subwoofer located below the seats handles low-frequency output in the factory configuration.
- Replacing the 4-inch midrange drivers may have a more noticeable impact on overall sound quality than tweeter replacement, as midrange frequencies carry much of the musical content and vocal clarity.
- The 1-inch tweeters handle high-frequency reproduction across four zones, potentially creating a diffuse soundstage depending on the factory crossover configuration.
- Aftermarket component speaker sets with 4-inch woofers and matching 1-inch tweeters could integrate into the existing mounting locations without requiring additional modifications.
- The below-seat subwoofer position may limit cone excursion capabilities compared to trunk-mounted alternatives, though it likely saves cargo space.
- Upgrading speakers in the front door locations tends to yield more perceptible improvements than rear-mounted replacements for most listening scenarios.
