Driver Specs:

1” Diamond Coated Tweeter

    FEA-optimized Organic Cell Lattice Diffuser for airy, unveiled highs and pristine clarity.
    Cutting-edge vapor-deposition grows a hyper-rigid diamond-like coating on an aircraft-grade aluminum dome, pushing high-frequency extension further beyond human hearing, and delivering best-in-class fidelity, linearity, and transient response.
    Silver tinsel leads for optimal signal transfer and power handling.

6.5” Woofer:

    Long stroke motor and suspension for high output.
    Composite glass-fiber cone with excellent stiffness/mass ratio for high sensitivity and pistonic behavior beyond passband.
    Precision-cast aluminum alloy baskets ensure precise alignment of critical components and maximize thermal dissipation.
    Vented aluminum voice coil former to maximize thermal control while minimizing air compression artifacts at high drive levels.

Crossover & Cabinet Specs:

Crossover:

    2-way crossover with premium-grade capacitors, inductors, resistors, and heavy-trace printed circuit board
    Tweeter-to-Woofer crossover: 1.8 kHz

Cabinet:

    Time-aligned cabinet geometry introduces microsecond-level time delays between the drivers, ensuring that the effective-acoustic-center of each driver is equidistant from the listener.   The result is improved linearity and directionality throughout the crossover frequencies, and a more accurate soundstage.
    Chamfered front baffle and flush-mounted drivers reduce edge diffraction and improve on-axis and off-axis high-frequency response.
    Extra-thick 1” (25mm) driver baffle ensures a rigid, resonance-free mounting for all drivers.
    FEA-optimized ¾” (18mm) cabinet construction, bracing, and acoustic insulation eliminate acoustic and structural resonances, ensuring an inert enclosure and an uncolored response, even at the highest drive levels.
