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 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 pass-band.
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 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 & Cabinet Specs:
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.
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.
