Two Great Whistles That Sound Great Together – Optimal Sound Power
As the worldwide leader in whistle technology, Fox 40 set out to develop a new whistle for the ever-changing demands in stadium and safety arenas worldwide. We looked at our bestselling whistles; the Fox 40® Classic® and the Fox 40 Sonik Blast®. The dependable piercing ultra high frequencies of the Classic’s upper chambers penetrate crowd and background noise in any situation. The lower chamber of the Sonik Blast generates a powerful and penetrating lower frequency to carry over longer distances. Fuzing these two designs, along with the patented Fox 40 CMG® comfort mouthgrip, finalized the whistle with a perfect sound and feel, creating optimal sound power.
