  • Aluminum dome for exceptional transient response

Triple 6.5” Woofers: 

  • Long stroke motor and suspension for high output
  • Polypropylene cone for excellent stiffness/mass ratio and pistonic behavior
  • Aluminum shorting ring to reduce gap inductance, lower distortion, and enhance high frequency response
  • Cast ABS-fiberglass composite basket ensures precision component alignment and excellent thermal transfer
  • Vented voice coil former minimizes air compression artifacts

5.25” Midrange Driver: 

  • 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 ABS-fiberglass composite basket ensures precision component alignment and excellent thermal transfer
  • Vented voice coil former minimizes air compression artifacts

Crossover & Cabinet Specs: 

Crossover: 

  • 3-way crossover with premium-grade capacitors, air-core inductors and heavy-trace printed circuit boards
  • 2-piece PCB design reduces component interference
  • Tweeter-to-Midrange crossover: 2.1kHz (12 dB/octave slopes)
  • Midrange-to-Woofer crossover frequency: 300Hz (12 dB/octave slopes)

Cabinet: 

  • Separate sealed midrange enclosure with angled bracing diffuses and shifts standing waves beyond the driver pass band, improving sound quality 
  • Three separate woofer enclosures with optimized port tuning frequencies for smooth and accurate bass response 
  • Acoustically transparent and FEA optimized grilles minimize diffraction 
  • Chamfered front baffle and flush-mounted drivers reduce edge diffraction and improved on-axis high frequency response
  • FEA-optimized cabinet and angled bracing eliminates resonances and improves cabinet rigidity for acoustically inert enclosure
