Sound design: Explosion

[Vibrations]

I want an evolving sound to end up with an explosion.
Any hints?

How about a firework slowed down.

if you got operator, i would layer some very low pitched noize looped wavforms oscilators, then for big blast some redux or distortion, and some chorus for the flangy motion effect.

I am using the Operator, a Redux, a Saturator and the Large Space Chorus Reverb preset.
Sounds great.
Thank you.

double the signal and transpose / use some extreme eq to get some sub-bass below the normal signal
