Frequently Asked Questions (FAQs)

1. Are coaxial car speakers any good?

In summary, coaxial speakers deliver good sound quality and good coverage of the entire range, and they are far superior to single-cone speakers found on factory cars. There are also 3-way coaxial speakers, but they are not as common as 2-way ones.

2. Is a round speaker better than a oval?

Since round component speakers are designed to provide separate frequencies for each range, they are able to provide a more accurate sound quality than oval coaxial speakers. A sound system using component (round) speakers, can provide much clearer audio than a simple coaxial 6×9 speaker can.

3. What does coaxial mean in car speakers?

Coaxial speakers in automobiles are 2- or 3-way loudspeakers in which the tweeter, or the tweeter and a mid-range driver, are mounted in front of the woofer, partially obscuring it. The advantage of this design is the ability to use a smaller area, hence their popularity in car audio.

4. Are coaxial speakers full range?

Coaxial speakers are often called "full-range" speakers because they reproduce a larger range of audio frequencies from a single unit. These speakers contain the same types of drivers that are found in component speakers, but they are combined to save on money and space.
