ESB Audio 9.6W Novemila 165mm Mid-Bass (pair)

ESB Audio 9.6W 6.5"/165 mm Woofer (pair)

Key Features

• The pole piece, designed with magnetic flux analysis software, helps achieve perfect and homogeneous saturation of the magnetic gap for the benefit of the voice coil movement. Immersed in a always constant magnetic flux, this reduces distortion and increases dynamics.
• Oversized Neodymium Magnet: This very powerful magnet is made of high-temperature resistant neodymium and allows for a significant reduction in the size and mass of the magnetic motor. An equivalent magnetic force from a normal ferrite magnet would require larger speaker dimensions.
• Pole plate with special ventilation ensures a long voice coil life.
• Terminals accept large cables and are gold-plated to prevent power loss from the amplifier.
• Die-cast aluminum and powder-coated basket offers extremely low resistance to air passage, and its shape (verified by FEM analysis) reduces vibration and resonance.
• Special spider device, screwed to the central pole, ensures the fixing of the spider damper.
• Conex™ spider damper is inside the voice coil with balanced and progressive stiffness for perfectly controlled movement.
• Huge voice coil ensures the highest power handling in its class and guarantees unparalleled speaker dynamics. The design of this voice coil ensures that it remains fully immersed in the magnetic field for most of its movement, minimizing distortion. The voice coil former is made of aluminum with ventilation holes and black anodization to improve heat dissipation. Underhung voice coil: the length of the voice coil winding is shorter than the height of the magnetic gap. This design allows for lower distortion at small displacements and more precise control of the voice coil movement.
• The cone is made of vacuum and autoclave-molded high-modulus carbon, a technology rarely used in loudspeakers due due to its cost, but it brings enormous advantages in terms of naturalness of reproduction and high transient dynamics.
• The NBL rubber surround has a shape designed to ensure a very smooth excursion with very small movements, becoming increasingly controlled as the movement increases and approaches the limit. This also helps to make this speaker very dynamic and capable of handling high powers.
• A CNC-machined aluminum ring fixes the rubber surround to the edge, ensuring perfect fixing and centering.
• CNC-machined aluminum protective grille (optional).
