Additional Notes
- The 1991 Ford Tempo front door panels accommodate 6.5 inch speakers, which may serve as either midbass drivers in a component system or full-range speakers for simpler installations. Midbass drivers typically handle frequencies from approximately 80 Hz to 500 Hz, providing the lower midrange punch that full-range speakers attempt to reproduce alongside higher frequencies. Component systems separate the frequency spectrum among dedicated drivers, whereas full-range speakers consolidate multiple frequency ranges into a single cone design.
- Rear deck lid positions in the 1991 Ford Tempo accept 6x9 inch speakers configured as full-range units. The 6x9 form factor offers greater cone surface area compared to round 6.5 inch speakers, potentially moving more air for bass response despite lacking the focused low-frequency extension of dedicated subwoofers. This oval configuration became popular in rear deck installations due to space constraints and the ability to produce a broader frequency range without additional amplification.
- Replacing factory speakers may address sound quality limitations inherent in original equipment audio components. Factory speakers often utilize lighter materials and simpler construction compared to aftermarket alternatives, which might feature polypropylene or treated paper cones, rubber surrounds, and higher-grade voice coils. The sensitivity rating of replacement speakers, measured in decibels, indicates how efficiently they convert amplifier power into acoustic output.
- The single DIN radio opening allows for head unit upgrades that might include enhanced equalizer controls, higher pre-amp voltage outputs, or digital signal processing. Higher pre-amp voltage, typically ranging from 2 to 5 volts, can drive aftermarket amplifiers more effectively while reducing noise susceptibility in the signal path. Some head units provide time alignment and crossover adjustments that could optimize the staging between front and rear speaker positions.
- Coaxial speakers represent the most common full-range design, mounting a tweeter concentrically above the woofer cone to handle frequencies above approximately 3,000 Hz. The built-in crossover network divides the frequency spectrum between the woofer and tweeter elements. Alternative component speaker systems place tweeters separately, often at ear level in door sail panels or A-pillars, which may improve high-frequency imaging and spatial presentation.
