Which kind of badminton string produces a fire-cracker or whip-like sound ?

I have heard many badminton players hitting their shuttlecocks with a loud and solid sound, similar to the sound of fire-cracker or a whip.





What kind of string is that ? Can anyone show me a link of the string or any examples ?





Thanks alot ...|||The string that usually makes a whip noise is in offensive rackets such as the yonex muscle power series. I bet you could make any racket sound like that when you if you hit it hard enough. I use yonex muscle power 2 and it makes that whip or firecracker sound. Check it out. 10 points please.
