CRSS_Speaker(krɔ’s spíːkər)

Configuration

1) 1.5 inch super tweeter

2) 4inch mid woofer

3) Concave reflection speaker box

4) Size 162mm(wide), 267mm(height), 215mm(depth), 3.2kg(weight)

                                                                            Side view

Sound waves emitted internally from the bottom-mounted mid-woofer are reflected by the “concave reflector (green)” and focused at the center of a pair of exponential reflectors (G). They are focused at the center of a pair of exponential curve apertures (yellow and vermilion).  As the sound waves travel from the focal point (G) to the exponential curve (F), they are converted to sound pressure. This conversion causes the sound waves to dissipate. Speaker drivers do not receive reflected sound waves                                    from inside the speaker box, resulting in extremely low distortion and high sound quality.  

 

CRSS_Woofer(krɔ’s wúfər)

Configuration                                                                                                         

1) 6inch woofer

2)  Concave reflection speaker box

3) Size  252mm(wide), 474mm(height), 325mm(depth), 10kg(weight)

                                                                                    Side view

 Sound waves emitted internally from the woofer are reflected by the “concave reflector” (green) and focused on the center of the aperture. They are focused to the center (G) of the aperture of a pair of exponential curves (yellow and vermilion). As the sound wave travels from the focal point (G) to the exponential curve (F), the sound wave is converted to sound pressure.                                                     This conversion causes the sound waves to dissipate. Since the speaker driver is not subject to reflected sound waves from inside the speaker box, the woofer has extremely low distortion and high sound quality.

The figure below shows a horizontal perspective view of the conventional speaker.　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　At the same time as the external radiation of Front sound waves (➜), the same amount of internal radiation of Back  sound waves (➜) is emitted inside the box. The internally radiated sound waves collide with the back of the speaker box.　A sound wave muffler (■) is installed on the back of the box to muffle the sound waves, but it cannot fully muffle the Back sound waves, especially those in the bass band, and they hit the cone paper of the speaker driver as internal reflection waves (➜), interfering with the external radiation (➜). This is what we call “distortion.
