- The dashboard location in the 1973 Chevrolet Blazer accommodates a 3.5 inch full-range driver, which suggests a single-cone unit handling the entire audible frequency spectrum without a dedicated tweeter or woofer component.
- A full-range driver at the dashboard position may tend to provide a centered soundstage, given its placement near the windshield and listener ear level.
- The rear door panel position supports a 4x10 inch oval full-range driver, a notably larger format that could allow for greater low-frequency cone excursion compared to the smaller dashboard unit.
- The size difference between the 3.5 inch dashboard driver and the 4x10 inch rear door driver suggests the rear positions might carry more of the low-to-mid frequency output, while the dash unit may lean toward mid-to-high frequency reproduction.
- Replacement priority might reasonably lean toward the rear door panel positions first, as the larger 4x10 inch drivers would likely contribute more noticeably to overall perceived audio output and bass response.
- Since both locations call for full-range types only, there would appear to be no factory provision for component speaker systems, which could limit high-frequency separation unless additional mounting solutions are considered.
