You could use "hypersonic." It is not a precise synonym, as subsonic is below the threshhold of hearing, whereas hypersonic would be above it. Supersonic would refer to velocity faster than the speed of sound, whereas subsonic also refers to velocities slower than those of the speed of sound.
Sonic velocities are a consideration in jet aircraft design and with bullets and marksmanship. Subsonic rifle bullets tend to be more accurate than hypersonic ones
