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.

5.25” Midrange Drivers

• 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 Kapton voice coil former is exceptionally lightweight for excellent dynamics and transient response.

8” 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:

• 3-way crossover with premium-grade capacitors, inductors, resistors and heavy-trace printed circuit board
• Tweeter-to-Midrange crossover: 1.8 kHz
• Midrange-to-woofer crossover: 140 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 8” 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 5.25” 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.
