ESB Audio 4.6C 2-way 6.5"/165 mm Coaxial (pair)

Main Features

• Pole piece CNC machined from ultra-low carbon alloy steel, designed with magnetic analysis software (FEM). Cold-formed from a single piece, the perfect geometry generates an additional concentration of magnetic force just in front of the voice coil, focusing the magnetic force where it is needed.
• The Y35 ferrite magnetic motor is optimized with FEA simulation to ensure a perfectly symmetrical magnetic flux in both directions of diaphragm movement. The metal parts of the motor are CNC machined from solid, refined material to achieve maximum magnetic flux linearity and minimal magnetic loss. This reduces distortion at high power levels.
• Die-cast aluminum alloy basket. This structural design offers excellent rigidity and minimal resistance to airflow movement without altering sound quality. The casting of this aluminum basket follows strict procedures to ensure compliance and help maintain consistent casting quality.
• CNC machined pole plate made from ultra-low carbon alloy steel. This type of manufacturing process ensures perfect flatness, so it sits perfectly on the magnet without reducing the critical magnetic flux.
• Large aluminum-copper clad vented voice coil can withstand very high power, reproducing music with extreme realism and high dynamics. The copper-clad aluminum wire voice coil is very lightweight and has excellent heat dissipation/capacity.
• The tweeter features a high-modulus silk dome for a soft sound, with an outer suspension coated with a high-loss damping material to eliminate edge vibration and resonance.
• Long-fiber, unbleached cellulose diaphragm with a special external treatment makes this material the perfect combination of lightness, stiffness, and internal damping.
• Surround made of soft nitrile rubber, UV-resistant and independent of temperature changes, to maintain the superior acoustic properties of this speaker over time. The special surround design ensures perfect and free forward and backward movement.
• CNC grille (optional)
