ESB Audio 9.UMA 3"/75mm Midrange + 1"/25mm Silk Dome Tweeter Mid-High Unit (Pair)

Key Features

  • Damping material controls the airflow of the tweeter and creates an aperiodic resistance.
  • Large neodymium magnet – high-temperature resistant, highly efficient. Special design precisely focuses magnetic flux without leakage.
  • Felt dampener to control and reduce tweeter dome resonance.
  • Wide 25mm lightweight aluminum voice coil with Cu-Al coating – significantly extends bandwidth.
  • Resin-impregnated silk dome with integrated suspension – one-piece construction, reduces weight, and allows for extremely high-frequency reproduction. Absence of joints prevents resonance phenomena.
  • CNC-machined aluminum flange – midrange and tweeter are screw-mounted, both can be replaced if needed.
  • Integrated connector between midrange and tweeter – pure gold-plated copper, accepts thick cables, secured with Allen screws.
  • TCA system controls the airflow of the midrange cone – aperiodic damping ensures fast and controlled energy release without persistent oscillations.
  • Die-cast and powder-coated aluminum frame (midrange) – minimal airflow resistance, FEM-optimized shape reduces vibration and resonance.
  • Wide lightweight Nomex voice coil with aluminum winding – significantly extends midrange bandwidth.
  • Large balanced Conex™ spider – ensures linear movement in both directions and reduces distortion.
  • Voice coil and cone connection collar – distributes pressure over a wide area, reducing deformation and distortion.
  • Cone made from high-modulus carbon fiber using vacuum and autoclave pressing – rare and expensive technology, but offers exceptionally natural reproduction and high dynamics in transients. One-piece without a dust cap – excellent dispersion and flat frequency response at the top end.
  • 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.
  • CNC-machined aluminum protective grille.
