DetailsAdvanced High-Power Mineral-Filled Co-Polymer Polypropylene Cones. Large, computer-optimized magnets and high-power motor structures promote natural and detailed sonic reproduction with outstanding extended bass response.
High-Pressure Die-Cast Aluminum Chassis and Mounting Brackets (selected models). The supremely rigid die-cast structure reduces resonances and standing waves, while the aluminum does double-duty as a heatsink.
High-Strength GRIP™ Glass-Reinforced Injection-Molded Polymer Chassis and Mounting Brackets (selected models). Design strength/rigidity reduces the problems of vibrations and resonances.
