Additional Notes

  • The 2009 Lexus IS350 uses a uniform 6.5 inch speaker format across both front door panels and rear deck lid locations, which may simplify the selection process when considering replacements.
  • Both front and rear positions accept either midbass drivers or full-range speakers, suggesting that the factory audio configuration likely relies on separate tweeters for high-frequency reproduction if midbass units are installed.
  • Full-range speakers in these locations could provide a simpler upgrade path since they incorporate tweeter elements directly into the speaker assembly, though midbass drivers paired with component tweeters might offer superior sound staging.
  • The rear deck lid placement typically faces upward and may benefit more from full-range speakers that can handle wider frequency ranges, while the front door positions are often better suited for component midbass drivers working with dash-mounted tweeters.
  • Upgrading the front door speakers might take priority over rear deck replacements, as front sound staging generally contributes more significantly to the listening experience for front-seat occupants.
  • The consistent 6.5 inch sizing suggests that depth and mounting requirements should be verified before installation, as door panels may have different clearance limitations compared to deck lid locations.
