Driver Specs:
1” Aluminum Dome Tweeter:
FEA-optimized diffuser for airy and unveiled presentation
Aluminum dome delivers exceptional transient response and exceptional stiffness/mass ratio
6.5” Woofers:
Composite glass-fiber cone with excellent stiffness/mass ratio for high sensitivity and pistonic behavior beyond pass band.
Aluminum shorting rings to reduce gap inductance and lower distortion
Long stroke motor and suspension for high output
Vented voice coil formers to minimize air compression artifacts at high drive levels
Crossover & Cabinet Specs:
Crossover:
2-way crossover with premium-grade capacitors, air-core inductors and heavy-trace printed circuit boards
Crossover frequency and slopes optimized for excellent off-axis polar response, outstanding phase coherency, and total radiated sound power
Tweeter-to-woofer crossover: 2 kHz
Cabinet:
Acoustically transparent and FEA optimized grilles, wedge-shaped front baffle and flush-mounted drivers all contribute to reduced edge diffraction and improved on-axis high frequency response
FEA-optimized bracing reduces cabinet resonances
