CRSS Speaker 
Construction
1) 1.5inch super tweeter
2) 4inch mid woofer
3) Concave reflection speaker box
4) Size 267mm(Wide), 267mm(Height), 215mm(Depth), 3.2kg(weight)
The figure below is a horizontal perspective.
The sound waves radiated into the cabinet from the mid-woofer mounted at the bottom of the speaker are reflected by the concave reflector (green) and focused at a focal point (G) located at the center of the opening formed by a pair of exponential curves (yellow and reddish-orange).
The concentrated sound waves then travel upward toward point (F) along the exponential curve surfaces. During this process, acoustic impedance transformation occurs, enabling the acoustic energy to be radiated forward with high efficiency. As a result, unwanted internal reflections and standing waves within the cabinet are significantly reduced, minimizing their adverse effects on the speaker driver.
Consequently, the system achieves low-distortion, high-fidelity, and high-resolution sound reproduction. Furthermore, because the structure requires only three additional internal panels, it remains remarkably simple while delivering excellent cost performance.
CRSS Woofer 
Configuration
1）6 inch woofer speaker
2）Concave reflect speaker box
3) Size 252mm(Wide), 474mm(Height), 325mm(Depth), 10kg(weight)
The figure below is a horizontal perspective view
The sound waves radiated from the speaker driver into the enclosure are reflected downward by the concave reflector (green) and concentrated at the focal point (G) located at the center of the opening formed by a pair of exponential curves (yellow and reddish-orange).
The sound waves focused at point (G) then travel downward toward point (F) along the exponential curve surfaces. During this process, acoustic impedance transformation takes place, allowing the acoustic energy to be radiated efficiently to the outside. As a result, the amount of acoustic energy trapped inside the enclosure is significantly reduced, and reflected waves returning to the driver are effectively suppressed.
Consequently, unwanted resonances and interference that cause sound coloration and loss of clarity are minimized, enabling the driver to reproduce its intended vibration characteristics more faithfully. This results in ultra-low distortion, high-fidelity sound reproduction, and exceptional resolution. Furthermore, the structure remains remarkably simple, requiring only three additional internal panels, while delivering outstanding cost performance.
Born from this innovative acoustic architecture is the CRSS Woofer, a revolutionary loudspeaker system that combines high performance with high efficiency.
