Until recent times, the phenomenon of secondary radiation (vibrations) from sources of sound reproduction systems was generally disregarded. This problem became apparent when, with technical progress, acoustic system elements reached superior quality. Equipment bodies and materials don’t keep developmental pace with their internal loudspeaker and power source components. As a result, they are prone to vibrations on their surfaces, what leads to adverse sound field effects.
Cold Ray's "Fractal 7" diffusers are designed to reduce the effects of sound reproducing equipment vibrations in a diffuse sound field. As all that is genius, this device’s working principle is simple, though it has its roots in fractal mathematics. To cope with secondary radiation, one has to “focus” and “neutralize” it. For this purpose Cold Ray Fractal 7, with its fractal-resembling cross-section, has enough weight and contact surface, yet not that much to become a secondary radiation source itself. What little vibration it doesn't absorb, it diffuses due to its fractal-resembling shape, thus making the vibrations even less prominent.
直到最近，來自聲音再現系統源的二次輻射（振動）現象普遍被忽視。隨著技術的進步，當聲學系統元件達到卓越的質量時，這個問題就變得明顯了。設備主體和材料跟不上其內部揚聲器和電源組件的發展步伐。因此，它們的表面容易發生振動，從而導致不利的聲場效應。
Cold Ray 的“Fractal 7”擴散器旨在減少擴散聲場中聲音再現設備振動的影響。由於這一切都是天才，這個設備的工作原理很簡單，儘管它起源於分形數學。為了應對二次輻射，人們必須“聚焦”和“中和”它。為此，Cold Ray Fractal 7 具有與分形相似的橫截面，具有足夠的重量和接觸面，但還不足以成為二次輻射源。它不吸收多少振動，由於它的分形形狀，它會擴散，從而使振動更加不突出。
