- The A-pillar location in the 2018 Ram ProMaster appears to house a relatively small 1.5-inch tweeter, which suggests that high-frequency reproduction at this position may be limited to dedicated tweeter units rather than broader speaker types.
- A tweeter in the A-pillar position tends to place high-frequency sound closer to ear level, which could contribute to a more focused soundstage compared to lower-mounted speaker placements.
- The front door panel location accommodates a 6.75-inch driver, and its compatibility with both midbass and full-range types suggests there may be some flexibility in how that position is approached during a replacement.
- A 6.75-inch midbass driver at the front door panel position would likely handle mid and lower-mid frequencies, potentially working alongside the A-pillar tweeter as part of a two-way configuration.
- If a full-range driver were used at the front door panel instead, it might cover a broader frequency spectrum on its own, though the degree of high-frequency extension could vary depending on the specific unit selected.
- Given that the front door panel holds a larger driver size, it may carry more priority in a speaker replacement context, as that location tends to have a greater influence on overall perceived audio output.
