[693i]

Infinity 6" x 9" three-way loudspeaker with Plus One woofer cone and silk-dome midrange and edge-driven silk-dome tweeter.Plus One woofer cones - This patent pending technology deliver a cone with more surface area than competing models of the same size. The result is increased bass output and higher efficiency. 
 
Edge-driven silk-dome midrange and tweeters - These are not commonly used W-domes, but fully edge driven domes like those found in fine home audio loudspeakers. This much larger voice coil increases power handling and provides better sonic integration with the mid-woofer.
