Play the setup (without changing anything) for another 100+ hours.
Never heard Omega's, bur have been using wide-band single driver speakers for 20+ years and even NOS from the 50's/60's need @ least 100/200 hours to sound like they WILL sound.
The drivers typically have an extremely low Xmax rating considering the frequency range they cover and it takes time/use to loosen up their stiff surrounds.
This seems to be the case with foam (Lowther et cetera) VS paper surrounds as well, which I don't understand, but it is what's reported.
All of my single drivers have folded paper surrounds which is the type that I believe Omega uses as well.
Mixing/changing things up during a new component break-in period just complicates achieving a solution to the issue(s) you are attempting to remedy.
