Crossover: 

3-way crossover with premium-grade capacitors, inductors, resistors, and heavy-trace printed circuit board 

Tweeter-to-Midrange crossover: 1.8 kHz 

Midrange-to-woofer crossover: 170 Hz 

Cabinet: 

Acoustically-centered architecture orients the mid-range and woofer arrays in rotational-symmetry around the tweeter, ensuring that low, mid, and high-frequencies emanate from the same effective point in space, creating a coherent, integrated, faithful acoustic image. 

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. 

Quad 5.25” woofers in Force-Balanced Opposed Array energize any room with deep, accurate, evenly distributed bass, whilst contributing a net-zero vibration force to the cabinet and other components. 

Dual 4.5” midrange drivers share a dedicated acoustic-suspension enclosure, symmetrical around the 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 baffles ensure 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
