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” 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
8” Woofers:
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:
3.5-way crossover with premium-grade capacitors, air-core inductors and heavy-trace printed circuit boards
Unique tapered midrange array miniimizes off-axis lobing and enhances radiated sound power into listening space
Top midrange-to-tweeter crossover: 2 kHz
Bottom midrange taper frequency: 700 Hz
Dual midrange-to-woofer crossover: 160 Hz
Cabinet:
Separate sealed midrange enclosures minimize top-to-bottom wall dimensions and shift standing waves beyond the driver pass band, minimizing negative driver interaction and associated frequency response degradation
Non-parallel cabinet panels reduces axial standing waves within the cabinet, reducing frequency response coloration
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, 1" thick midrange/tweeter baffles and 1.5" thick woofer baffles eliminates structural resonances and ensures the cabinet remains acoustically inert for uncolored response even at the highest drive levels
