Additional Notes

  • The 2014 Audi S4 features a multi-location speaker configuration with tweeters positioned in the dashboard, front door panels, and rear door panels, each measuring 1 inch in size.
  • A 2.5 inch midrange speaker in the center dash location handles mid-frequency reproduction, which typically contributes to vocal clarity and instrumental presence in the sound stage.
  • The rear deck lid contains two distinct speaker sizes: a 3.5 inch full-range unit and an 8 inch woofer, suggesting a dual-purpose approach to rear audio coverage.
  • Both front and rear door panels accommodate 6.5 inch speakers that accept either midbass or full-range drivers, providing flexibility for audio system upgrades depending on whether component or coaxial configurations are preferred.
  • Component speaker systems might be prioritized for the door panel locations since separate 1 inch tweeters are already installed in multiple positions throughout the cabin.
  • The 8 inch woofer location in the rear deck lid could be targeted for replacement when seeking enhanced low-frequency output, as dedicated woofers generally focus on bass reproduction between approximately 40-200 Hz.
  • Tweeters at 1 inch typically handle frequencies above 3-4 kHz, so replacement options in the dashboard and door panel locations would likely focus on high-frequency extension and off-axis response characteristics.
  • The full-range 3.5 inch speaker in the rear deck lid may serve as rear fill, though its smaller size suggests limited low-frequency capability compared to the adjacent 8 inch woofer.
