Additional Notes

  • The 1991 Mitsubishi Eclipse factory audio configuration includes four distinct speaker locations, each serving different frequency reproduction roles within the sound system.
  • Dashboard speakers are limited to 4-inch midrange drivers, suggesting these units handle primarily vocal and instrument frequencies rather than bass or extreme high frequencies.
  • Both front and rear door panels accommodate 6.5-inch speakers, with compatibility extending to either midbass or full-range driver types depending on system design preferences.
  • The rear side panel position accepts 6x9-inch speakers designated for full-range operation, which typically allows these larger drivers to reproduce a broader frequency spectrum than smaller alternatives.
  • Door panel speakers might be considered higher priority for replacement in the 1991 Mitsubishi Eclipse, given their larger size and potential for greater impact on overall sonic output compared to dashboard units.
  • Full-range speakers in the door and rear side positions could theoretically reproduce bass, midrange, and treble frequencies without requiring separate tweeters or woofers in those locations.
  • Midbass drivers would focus on lower midrange and upper bass frequencies, potentially benefiting from additional tweeters to handle higher frequencies if installed in the door panels.
  • The single DIN radio opening indicates a standard-height head unit cavity, which relates to aftermarket receiver compatibility but does not directly affect speaker selection beyond potential amplifier power considerations.
  • Replacing factory speakers with aftermarket units of matching sizes could potentially improve clarity, volume capability, and frequency response across the listening environment.
  • The 6x9-inch rear speakers offer a larger cone area than the 6.5-inch door speakers, which may contribute to increased bass output potential from that location without additional subwoofer installation.
