Additional Notes
- The 1989 Audi 90 dashboard positions accommodate 4-inch midrange speakers, which handle vocal and instrumental frequencies without extending into deep bass or high treble ranges.
- Replacing dashboard speakers may address clarity in the upper-midrange spectrum, though the limited cone area restricts low-frequency output inherently.
- Rear deck lid locations accept 6.5-inch speakers with options for either midbass or full-range configurations, offering flexibility based on system design preferences.
- Midbass speakers in the rear deck would complement the dashboard midranges by reproducing lower frequencies that 4-inch drivers cannot adequately produce.
- Full-range speakers in the rear deck positions could function independently without requiring additional tweeters, though performance across the entire frequency spectrum tends to involve compromises.
- The larger cone surface area of 6.5-inch speakers typically produces more substantial bass response compared to smaller dashboard units.
- Prioritizing rear deck replacements might yield more noticeable improvements in overall sound quality due to the greater potential for bass reproduction and higher power handling.
- Aftermarket speakers in the 6.5-inch size category generally offer wider selection and potentially better value compared to the less common 4-inch midrange market.
