Additional Notes

  • The 2007 Lexus IS350 uses a uniform 6.5 inch speaker size across both front door panels and rear deck lid locations, which may simplify the replacement process when sourcing aftermarket components.
  • Both front and rear positions accept either midbass or full-range speaker types, giving the installer some flexibility in choosing between dedicated frequency-specific drivers or single-driver solutions.
  • Midbass speakers in these locations would typically handle frequencies from approximately 80Hz to 4kHz, while full-range speakers would attempt to reproduce a broader spectrum from lows through highs in a single driver.
  • The door panel locations often benefit most from aftermarket replacement, as these positions handle the majority of vocal and instrumental content that listeners notice most readily during typical listening.
  • Full-range speakers installed in the 6.5 inch openings would eliminate the need for separate tweeters in those locations, though they may not match the clarity of component systems with dedicated high-frequency drivers.
  • The rear deck lid placement suggests a traditional sedan-style speaker configuration, where rear-firing drivers project sound upward and reflect off the rear window.
  • Aftermarket midbass drivers in the front doors could work in conjunction with separate tweeters to create a component system with potentially improved imaging and frequency separation compared to the factory setup.
