What is the difference between coaxial and component speakers as they pertain to car audio?
Generally, coaxial speakers consist of a midbass woofer running full range, wired in parallel with a tweeter mounted above the center of the woofer. The tweeter might be monted at an angle and will have an in-line capacitor which acts as a high pass filter. Component speakers, on the other hand are made up of a woofer, tweeter, and an external passive crossover. The crossover, at minimum, will consist of a capacitor (bass blocker) which will connect to the tweeter, an inductor (high blocker) which will connect to the woofer, and an L pad which will also connect to the tweeter (controls how loud the tweeter is). Most of the time, this Lpad is adjustable. The advantages of coaxial speakers are: Because the two drivers are already hard-wired together, the only speaker wire that needs to be run is from the source to the speaker. With component speakers, you will need to wire the source, woofer, and tweeter, all to the crossover. Coaxial speakers on the market tend to require less power to
