ESB Audio 9.4M Novemila 4"/100mm Carbon Fiber Midrange Speaker + CNC Grille (Pair)

Key Features

• Magnetic pole anchor designed with magnetic flux analysis software – ensures perfect and homogeneous saturation in the magnetic gap, improves voice coil movement, reduces distortion, and increases dynamics.
• Pure copper ring in the air gap – reduces voice coil inductance, minimal resistance in high-frequency reproduction, better transient response, and more accurate sound reproduction.
• TCA system controls cone airflow – aperiodic damping ensures fast and controlled energy release without persistent oscillations. More accurate and faithful response to the sound source.
• Dual neodymium magnet (twin coupled) – high-temperature resistant, one of the most powerful motor structures for car speakers of this size. High-quality neodymium allows for a compact motor.
• Pole plate CNC machined from a single piece of ultra-low carbon steel.
• Integrated large gold-plated terminals – accept thick cables, preventing amplifier power loss.
• Die-cast and powder-coated aluminum frame – minimal air resistance, FEM-analysis optimized shape reduces vibration and resonance.
• Wide lightweight Nomex voice coil with aluminum winding – significantly extends bandwidth.
• Large balanced Conex™ spider – ensures linear movement in both directions and reduces distortion.
• Cone made from vacuum and autoclave pressed high-modulus carbon fiber – rare and expensive technology, offers exceptionally natural reproduction and high dynamics in transients.
• NBL rubber surround – shape designed to ensure very smooth movement at small amplitudes, becoming more controlled as amplitude increases. Makes the speaker very dynamic and powerful.
• Laminated aluminum dust cap – extends the frequency range upwards, shape and size flatten and linearize the frequency response.
• CNC-machined aluminum ring secures the rubber surround to the edge – ensures perfect attachment and centering.
• CNC-machined aluminum protective grille included in the package.
