Eliminating resonance in speakers results in a wide, smooth response and low distortion., Polymer Composite Woofers: The speaker features two 5-1/4" polymer composite woofers for smooth wide-range response with low distortion. For high performance durability, each woofer uses a butyl rubber surround and an acoustically inert stamped driver basket., Silk/Polymer Tweeter: The speaker has a 1" silk/polymer dome tweeter that provides clear, detailed highs. The tweeter uses a heat sink on the Neodymium magnet for superior heat dissipation, power handling and reliability., Frequency Response |
