Product Research
Plus One Woofer Cones: This speaker uses a cone approximately 30% 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: The 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.
Surrounds: The Hi-Roll rubber surround allows the woofer a greater range of movement, resulting in longer X-max and more bass output.
Tweeters: This speaker uses a 3/4" silk dome tweeter for smooth, accurate highs. The UniPivot tweeter is angled (non-adjustable) and may be turned up to 355 degrees for optimum imaging and in-car frequency response. It is NOT made to turn 360 degrees. If the tweeter is turned 360 degrees or more, it will be damaged.
