- The 2017 BMW Alpina B7 features a multi-component speaker system with separate tweeters and midrange drivers distributed across multiple cabin locations, suggesting a factory-installed premium audio configuration that separates frequency ranges for potentially enhanced sound staging.
- Tweeters of 1 inch are positioned in four distinct locations throughout the cabin, which may indicate an attempt to distribute high-frequency sound evenly across both front and rear seating areas.
- The 4 inch midrange speakers mirror the tweeter placement pattern, installed in the center dash, front doors, rear doors, and rear deck lid, creating parallel frequency-specific arrays that could contribute to a more defined soundstage.
- An 8 inch subwoofer located below the seats handles low-frequency reproduction, a placement that might help preserve cargo space while still providing bass reinforcement to the overall sound system.
- Replacement of the midrange speakers might take priority for those seeking sound improvement, as these 4 inch drivers handle the critical midrange frequencies where most vocal and instrumental content resides.
- The tweeter locations in both door panels and deck areas suggest that upgrading these components could influence spatial imaging and high-frequency clarity, particularly for rear seat passengers.
- The under-seat subwoofer configuration may present specific fitment considerations, as replacement options would need to account for the spatial constraints of this mounting location.
- Component speaker systems designed with separate tweeters and midrange drivers would align with the factory configuration, potentially simplifying installation while maintaining the intended frequency separation architecture.
