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 carbon 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 for optimal signal transfer and power handling
6.5” Mid-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 pass-band
• 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
• 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.
