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
