    Precision-cast aluminum-alloy baskets ensure precise alignment of critical components and maximize thermal dissipation.
    Vented Kapton voice coil former is exceptionally lightweight for excellent dynamics and transient response.

6.5” Woofers:

    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:

    3-way crossover with premium-grade capacitors, inductors, resistors and heavy-trace printed circuit board
    Tweeter-to-Midrange crossover: 1.9 kHz
    Midrange-to-woofer crossover: 160 Hz

Cabinet:

    Acoustically Centered Time Alignment architecture.
    Acoustically-centered architecture orients the mid-range and woofer arrays in rotational-symmetry around the tweeter, ensuring that low, mid, and high-frequencies emanate from the same effective point in space, creating a coherent, integrated, faithful acoustic image.
    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.
    Quad 6.5” woofers in Force-Balanced Opposed Array energize any room with deep, accurate, evenly distributed bass, while contributing a net-zero vibration force to the cabinet and other components.
    Dual 4.5” midrange drivers share a dedicated acoustic-suspension enclosure, symmetrical around the tweeter.
    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 baffles ensure a rigid, resonance-free mounting for all drivers.
    FEA-optimized ¾” (18mm) cabinet construction, extensive bracing, and acoustic insulation eliminate acoustic and structural resonances, ensuring an inert enclosure and an uncolored response, even at the highest drive levels.
