- The A-pillar tweeters in the 2018 Acura TLX handle high-frequency reproduction, which suggests that replacing these 1-inch drivers could refine the upper-range clarity and detail in the soundstage.
- The front door panels accommodate 6.5-inch speakers compatible with both midbass and full-range drivers, indicating flexibility in choosing between dedicated frequency-specific components or broader-spectrum replacements.
- An 8-inch subwoofer location exists in the rear deck center, which would typically address low-frequency extension and bass impact when upgrading the factory audio system.
- The 3.5-inch center dash speaker functions as a full-range driver, likely contributing to vocal clarity and center imaging, particularly for front-seat passengers.
- Rear door panels utilize 3.5-inch midrange speakers rather than full-range drivers, suggesting a factory configuration that dedicates these speakers to mid-frequency reproduction while relying on other locations for highs and lows.
- The rear deck lid contains 6.5-inch speakers with midbass or full-range compatibility, mirroring the front door configuration and potentially providing rear-seat passengers with similar frequency coverage options.
- The presence of dedicated tweeters, midrange drivers, and a subwoofer location indicates a multi-way factory system design, where replacing front door and rear deck speakers might yield the most noticeable improvement in overall sound quality.
