- The 2011 Infiniti M37 factory audio system includes a relatively unusual headrest speaker configuration with 2 inch tweeters, which may contribute to a more immersive surround sound experience for rear passengers.
- Replacing the rear door panel speakers with 6.5 inch aftermarket midbass or full-range units could provide noticeable improvements in bass response and overall sound quality, as these larger drivers typically handle lower frequencies more effectively than smaller components.
- The front door panel contains a multi-speaker array consisting of 1 inch tweeters, 3 inch midrange drivers, and 6x9 inch full-range speakers, suggesting a three-way component system design that separates frequency ranges for potentially clearer reproduction.
- The 10 inch rear deck center subwoofer location indicates that factory low-frequency reinforcement comes from a centrally positioned driver rather than dual subwoofers, which might influence replacement strategy for those seeking enhanced bass output.
- The center dash 3 inch midrange speaker likely handles critical vocal frequencies and dialogue reproduction, making its performance particularly important for overall tonal balance in the 2011 Infiniti M37 cabin.
- The 3 inch rear deck lid full-range speakers probably serve as rear fill components, adding ambient sound to the listening environment without handling significant bass frequencies given their smaller size.
- Upgrading the front door 6x9 inch full-range speakers might yield the most substantial improvement in sound quality, as these drivers handle a broad frequency spectrum and typically contribute significantly to overall output in factory systems.
- The combination of different speaker sizes and types throughout the cabin suggests a multi-channel factory audio architecture that attempts to create spatial imaging through strategic placement of various driver configurations.
