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.

4.5” Midrange Driver

• 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.

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:

• 3-way crossover with premium-grade capacitors, inductors, resistors, and heavy-trace printed circuit board
• Tweeter-to-Midrange crossover: 2.2 kHz
• Midrange-to-woofer crossover: 450 Hz

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.
• Vertically Aligned Tweeter-Midrange array creates perfect on and off-axis frequency response and blending for clear vocals and the largest possible “Sweet Spot” ensuring transparency and clear vocals at every listening position.
• Dual 6.5” woofers drive deep, accurate bass for the most demanding center-channel content.
• 4.5” midrange driver in a dedicated acoustic-suspension sub-enclosure ensures pristine midrange output and blending with woofers and 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 baffle ensures 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.
