– Ultra-low carbon alloy steel pole piece CNC-machined using magnet
analysis software (FEM), cold forged in one-piece creates a perfect geometry. This produces an extra magnet force concentration just in front of the voice coil, focusing the magnetic force where needed.
– The Y35 ferrite magnet motor is optimized with FEA simulation to ensure a perfectly symmetrical magnetic flux in both directions of cone’s run. Motor metal parts are CNC machined from solid, refined material for maximum magnetic flux linearity and minimum magnetic loss. This reduces distortion at high power levels.
– Die cast aluminum alloy basket frame. This design structure offers great rigidity and minimal resistance to airflow movement without altering sound quality. The casting of this aluminum basket follows strict procedures that ensure compliance with regulatory specifications and help maintain consistent casting quality.
– CNC-machined ultra-low carbon alloy steel pole plate. This type of
manufacturing process ensures perfect flatness so it sits perfectly flush over the magnet without reducing any crucial magnetic flux.
– The large aluminum copper-clad vented voice coil can handle very high power while reproducing music with extreme realism and high dynamics. The copper clad aluminum wire voice coil is very lightweight and with excellent heat dissipation/capacity.
– Long-fiber, unbleached pulp cone with a special external treatment that makes this material a perfect combination of lightness, rigidity, and internal damping.
– Surround suspension made of soft nitrile rubber, UV-resistant, and unaffected by temperature change so that the superior acoustic qualities of this speaker are preserved long-term. Special edge design ensures perfect and free forward and backward movement.
– Deluxe protective stainless-steel grille.
