    The ESB 9.UMA is a sophisticated 2-way mid/high “unit” combining a midrange driver and tweeter in a single integrated package. It’s engineered to minimize phase delay between the drivers by centering them in one flange, offering coherent imaging and uniform response. With premium materials — carbon cone, neodymium motor, silk dome tweeter, and advanced airflow control — it’s built for high-end systems needing compact form and audiophile-level fidelity.

    • Model: 9.UMA
    • Type: 2-Way high-end mid / high “unit” (midrange + tweeter integrated)
    • Nominal Impedance: 4 Ω
    • Power Handling (RMS): 110 W
    • Transient / Peak Power: 220 W
    • Frequency Response: 130 Hz – 25,000 Hz
    • Sensitivity: 91.5 dB (mid and tweeter) @ 2.83 V / 1 m

    Construction / Design Highlights:
    • Damping material to control tweeter airflow and provide aperiodic resistance
    • Large, high-temperature neodymium magnet with optimized magnetic flux design
    • Felt damper to reduce resonance in tweeter dome
    • Tweeter: 25 mm lightweight aluminum voice coil with aluminum-copper clad winding for wide bandwidth
    • Silk dome (resin impregnated) with integrated suspension — made in one piece to reduce weight and avoid break-up
    • CNC-machined aluminum flange to mount midrange and tweeter together
    • Integrated gold-plated copper terminal connector between midrange and tweeter
    • TCA (Tuned Cavity Airflow) system managing airflow from midrange cone to reduce resonant artifacts
    • Basket for the midrange: die-cast aluminum, powder-coated, shaped for low airflow resistance and vibration control
    • Midrange voice coil: Nomex former with aluminum winding for wide bandwidth and linear response
    • Spider: Balanced Conex™ spider for controlled linear excursion
    • Cone: High-modulus carbon cone molded under vacuum and autoclave, no separate dust cap (single-piece design)
    • Surround: NBL rubber surround shaped for smooth motion at low excursion, more controlled at higher excursion
    • CNC-machined aluminum optional grille
