The unique hexagonal shape of the Xtant X series subwoofer provides an increase in cone surface area of approximately 10% over conventional round woofer products. 
The increase in cone area translates directly to an increase in sound pressure levels given the same excursion. This increase in cone area and subsequent SPL does not come at the expense of installation ease, as the basket fits perfectly into a standard round enclosure cutout. 
The cone of the "X" series woofer is injection-molded using mica filled polypropylene. Polypropylene is very stable material that lends itself well to the automobile environment. We use a mica filler that improves the damping capabilities of the poly and significantly improves frequency response. 
The front side of the cone is coated with a layer of aluminum which works in conjunction with the machined finish of the cone tool to provide a unique and dynamic look to the product. 
The surround / gasket combination is compression-molded using Nitrile Butadiene Rubber. NBR combines great damping capabilities with extreme resistance to ultra-violet rays. The dust cap is injection-molded polypropylene with the embossed Xtant logo. 
The spider is a laminated, 2-layer design. Nomex and polycotton are hot-pressed together resulting in a material that ensures maximum longevity, while still providing tremendous flexibility. 
The die cast steel yoke has a smooth CNC-machined finish and features a de-bossed Xtant logo. 
The stamped steel front plate is machine turned to ensure the tightest tolerances available while providing a high quality look. 
The custom tooled basket is constructed of die cast aluminum.

The X2 subwoofer takes a proven design to the next level. Many of the same revolutionary features that Xtant woofers have been known for have been carefully carried through an evolution to bring you X2. Increased power handling, increased motor size and strength, along with increased displacement collaborate to make the X2 subwoofer the best in its class. The Hex-shaped cone (Patent 6,567,529) with aluminum honeycomb dust cap provides approximately 10% more cone area than conventional round woofers. This means you get first class engineering, exclusive style, and high performance SPL from Xtant's hexagonal cone. The Hex-shape compression molded gasket also allows multiple woofers to be mounted side-by-side creating a "honeycomb" affect for maximum bass performance. Other innovative features of the X2 subwoofers from Xtant include:
 

The Xtant X2 series subwoofers are sure to be a box office hit. The components in the new X2 woofer have all undergone technological advancements in every category. As if that weren't enough, the new line displays stylish cosmetic features that set it apart from any other brand in the industry displaying class and grace while still looking bold. While most people buy woofers that fit in with their car, Xtant X2 owners will buy cars that will maintain the image and performance of their X2 woofers.
