Product Description
Firstly, the tweeter in all models is a 25mm textile dome, Ferro fluid cooled unit powered with an ultra-strong neodymium magnet for the fastest, most accurate response we have ever achieved. Next, the woofer cone is made from a bi-directional KEVLAR weave self-damping in nature, reducing resonant frequencies to virtually negligible levels. The impetus for rapid movement here is a dual layer, vented voice coil, which transmits the signal information with the highest levels of accuracy. The cone is mounted on a nitrile rubber `Flexaural surround rim. A profiled phase plug improves the off-axis performance to project an excellent stereo image across a wide listening area.
