Factory speakers

These are the stock speakers that come with your car or vehicle. It is usually mounted on the front doors, rear deck, and soundbar. These speakers are designed to provide you with enough music, especially if you drive for short distances.

Component Speakers

This is the most expensive speaker set you can purchase. The main difference with this type of car speaker is that they are composed of three separate speaker types, which include woofers, tweeters, and midranges.

This is the speaker responsible for high frequencies, namely treble sounds, which you hear while listening to your favorite music. Since coaxial speakers have one woofer and tweeter, these are mostly used in factory-installed speaker systems.

Mid-range vs. Full-range speakers

A midrange speaker is the one that handles mid-range sounds, meaning everything in between high and low frequencies. On the other hand, full-range speakers are able to handle both low and high-range frequencies.

The difference between midrange and full-range speakers is usually seen in their sizes. The midrange speakers are slightly larger than the full-range ones, which can fit in any 6.5-inch slot. Your sound system needs a proper enclosure.
