- The dashboard position in the 1989 Chevrolet Blazer uses a 3.5 inch full-range driver, which suggests it may have been a lower-priority installation compared to the larger rear placement, given the relatively small cone area and its likely limited low-frequency output.
- The rear door panel position accommodates a 4x10 inch oval full-range driver, which tends to offer a wider radiating surface than the dashboard unit, possibly allowing for a broader frequency response from a single driver without the need for supplemental components.
- Both positions are specified as full-range compatible only, which could indicate that the factory configuration was not designed around a multi-way or component speaker arrangement, potentially leaving some portions of the audible frequency range less represented.
- Given the size disparity between the two positions, the rear door panel speakers would likely contribute more to overall acoustic output, suggesting that replacement efforts there could yield a more noticeable change in perceived sound quality relative to the dashboard position.
- The 4x10 inch oval format is a less common sizing in contemporary aftermarket offerings, which may mean that sourcing direct-fit replacement drivers for the rear door panel could involve more limited options compared to the 3.5 inch dashboard position.
