The speakers also include a 6.5" composite fiberglass woofer, resulting in a deep, thumping bass, as well as a 1" chambered aluminum dome tweeter, located above the woofer. These features are responsible for delivering high-quality and high-quantity low-frequencies, and helping to ensure that no one frequency will be dominating another. The added rear venting feature also provides for a more powerful bass response for the relatively small size of the speaker.
