Driver Specs: 

1” Aluminum Dome Tweeter: 

  • Vertically aligned tweeter and midrange improves horizontal axis polar response, with reduced lobing and comb filtering 
  • FEA-optimized diffuser for airy and unveiled presentation 
  • Aluminum dome delivers exceptional transient response and exceptional stiffness/mass ratio 

4” Midrange Drivers: 

  • Composite glass-fiber cone with excellent stiffness/mass ratio for high sensitivity and pistonic behavior beyond pass band 
  • Aluminum shorting ring to reduce gap inductance, lower distortion, and enhance high frequency response 
  • Cast aluminum basket to ensure precise alignment of critical components and additional heat-sinking capacity 
  • Vented voice coil former to minimize air compression artifacts at high drive levels 

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
  • Cast aluminum basket to ensure precise alignment of critical components and additional heat-sinking capacity
  • Vented voice coil formers to minimize air compression artifacts at high drive levels

Crossover & Cabinet Specs: 

Crossover: 

  • 3-way crossover with premium-grade capacitors, air-core inductors and heavy-trace printed circuit boards
  • Midrange-to-tweeter crossover: 2.2 kHz
  • Midrange-to-woofer crossover: 500 Hz

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
