Tweeter with Wide-Dispersion Waveguide The tweeter features a wide-roll surround and brings response up to 35 kHz for enhanced high frequencies. The waveguide also helps improve directivity control and eliminate the diffraction modes common to speaker enclosures. Woven Aramid-Fiber Woofers & Mid-Woofer The shape of the aramid fiber cone is designed to offer augmented stiffness and damping characteristics over polypropylene or paper cones, helping to achieve a smoother, extended low-frequency response. The woofers and mid-woofer also feature an oversized magnet and a vented pole piece. Braced MDF Cabinets The cabinets are internally braced for enhanced stiffness and strength, reducing cabinet vibrations that cause unwanted coloration.
