- The dashboard location in the 1979 Chevrolet Blazer uses a 3.5 inch full-range speaker, which suggests it handles the entire audible frequency spectrum from a single driver unit, covering highs, mids, and lows without a supplementary tweeter or woofer.
- The rear door panel position accommodates a 4x10 inch oval full-range driver, a less common size that may present some difficulty when sourcing direct replacement options compared to more widely produced round speaker sizes.
- Given the rear door panel's considerably larger cone surface area relative to the dashboard position, the rear placement could potentially contribute more acoustic output and low-frequency response than the front dashboard speakers.
- Since both locations rely on full-range drivers rather than component systems, there would likely be no passive crossover network present in the factory configuration, which tends to limit high-frequency clarity and overall sound staging.
- The dashboard position, at 3.5 inches, may be considered a higher replacement priority for perceived sound quality improvement at the listening position, since front-facing drivers typically have a more direct path to the occupants' ears.
- Upgrading either position with a higher-sensitivity full-range driver could result in noticeably louder output without requiring additional amplification, given that the original factory system was likely low-powered.
