Speaker Types

Additional Notes
- The rear side panel location in the Nissan 370Z is a compact, enclosed mounting position integrated into the vehicle's interior side structure behind the seats.
- A 2-seat sports car body style constrains rear interior volume significantly, which limits the physical depth and diameter available for speaker mounting in the rear side panel area.
- The 3.5-inch diameter specified for the Nissan 370Z rear side panel reflects the restricted cavity dimensions typical of a compact, fixed rear panel in a coupe platform.
- A 3.5-inch speaker cone surface area is considerably smaller than standard mid-size drivers, which concentrates its output in the upper portion of the midrange and reduces low-midrange extension.
- The rear side panel position places the speaker at a lateral angle relative to the listening position, meaning sound reaches the occupants partly through reflections off the cabin surfaces rather than direct radiation.
- Midrange drivers are designed to reproduce frequencies roughly between 300 Hz and 5,000 Hz, covering the vocal and instrumental presence range that is most sensitive to human hearing.
- At 3.5 inches, the driver's relatively limited cone mass allows faster transient response in the upper midrange frequencies, where detail and articulation in vocals and instruments are most prominent.
- The rear side panel mounting orientation in a coupe typically results in the speaker facing inward toward the cabin, which influences how midrange frequencies interact with the seat structures and interior trim.
- Midrange drivers function without the need for ported or vented enclosures in many automotive installations, making them suitable for the sealed panel cavities common in rear side locations.
- The Nissan 370Z rear side panel speaker opening accepts only the 3.5-inch format across all model years from 2009 through 2020, indicating a consistent chassis mounting structure throughout the production span.
