The original Stasys X set new standards in the performance possible from a double 18” low frequency enclosure. Used on tours, in live venues, and in world-class night venues all around the world, the Stasys X V2 now benefits from newer technologies to advance and refine the design further.A total rearrangement of the internal resonant chambers has improved the cooling to the extent that no external heatsinks are required, which has led to a significant decrease in power compression. The system's transient response, phase response, and overall timing capabilities have also been vastly improved by the new internal chamber layout. This has led to a more uniform response in relation to distance, and greater behavioral predictability when arrayed.The two neodymium 4" voice coil 18" low frequency drivers use the latest cone materials to keep the moving mass low enough to allow optimum transfer efficiency, whilst providing the structural rigidity to maintain form at all times. This advancement has also meant that the transducers' mechanical parameters are ideally matched to the enclosure's internal loading requirements, which has lowered the f3 point and improved the attack characteristics.Sprayed with our brand new ‘TourCoat’ polyurea finish, the 18mm birch plywood cabinet also features new truck pack friendly dimensions and universal location receptors that allow interlocking and mating with adjacent enclosures regardless of their orientation.- See more at: http://voidacoustics.com/docs/products/Stasys_X_V2.shtml#sthash.ho1gwkfY.dpuf
