For any car audio sound system the speakers are the key to good or bad sound. Speakers in your home sound system have the luxury of being able to use larger sized boxes that embraces better sound quality. Car audio systems however are more restricted in the amount of space for speakers to operate efficiently. This is where coaxial speakers come in to play. A typical coaxial car speaker is a 2 or 3 in one speaker where the speakers are all mounted on the single main driver. This eliminates the need for large speaker boxes where all speakers are mounted separately. Coaxial speakers allow good speakers to be mounted in a smaller space, and, going by the many coaxial speaker reviews they can certainly put out amazing sound quality.
