- The dashboard location in the 1985 Ford Sierra takes a 4-inch midrange driver, which suggests it handles a narrower frequency band rather than the full audio spectrum. A dedicated midrange unit in that position may reproduce vocals and mid-frequency content with somewhat greater clarity than a full-range alternative would in the same space.
- The rear side panel accommodates a 4x6-inch oval configuration, paired with a full-range compatible type. This oval format tends to offer a slightly wider radiating surface than a round 4-inch unit, which could contribute to a broader low-frequency response from that location.
- Given that the rear side panel runs a full-range type while the dashboard relies on a midrange-only driver, the dashboard position may represent the higher priority for replacement if overall frequency coverage across the listening space is a concern. The midrange-only designation at the front could mean low-frequency content is notably absent from that channel.
