What is the speed of sound in Zero-K?

I want to mod Archer to be support and take away the water gun and give it use a Sonic Blaster and make it stop to fire like Fencer so it will be useful by being able to crack the touch shell of a Scallop with a powerful impulse effect, but will still be eaten by a swarm of Ducks.

There is one clearly sonic weapon. It is Siren's Sonic Blaster and it travels at 700 elmo/s. Are all sonic weapons limited to that speed? Are Gauss weapons in Zero-K sonic weapons?

If you really want to approach your design fluff-first, then my fluff for the sonic cannon is that it is some kind of a vortex gun and the vortex actually travels at speed different from the speed of sound.

However, i would suggest a balance-first approach where you can just write fluff around whatever the game needs.

It is finally revealed that 1 metre = 8 elmos.
