Plus One+ Woofer Cones: Each speaker uses a cone significantly larger than other speakers of the same size. This is accomplished by using a new basket design and hi-roll surround. The Plus One+ design offers greater bass output and a significant increase in efficiency.
Woofer Materials: Each woofer is constructed from Injection-Molded Polypropylene. This process of cone molding assures a uniform cone thickness for superior linearity and clarity. It is also lighter weight and more rigid for decreased distortion and improved bass response.
Hi-roll Rubber Surrounds: The hi-roll rubber surrounds allow the woofers a greater range of movement, resulting in longer X-max and more bass output.
3/4" Textile Dome Tweeters (UniPivot Design): Each speaker uses a 3/4" edge-driven textile dome tweeter for smooth, accurate highs. The UniPivot tweeters are angled (non-adjustable) and may be turned up to 355 degrees for optimum imaging and in-car frequency response.
Note: The tweeters are not made to turn 360 degrees. If they are turned 360 degrees or more, they will be damaged.
