Is there something about the Omnisats you don’t like or are you just curious if the QS speakers are better? I have QS8s but haven’t heard the Omnisats so I can’t give a direct comparison. Since they are both designed to diffuse sound out I can’t say they would be all that different.
Maybe someone will show up who’s heard both and can give you a better answer but if not you could always order a pair of QS speakers for a 30 day demo and ship them back if they’re not worth the upgrade. Here is Axiom’s return policy and estimated shipping costs:
As for QS4 or QS8 I would check out their specs and see which seems to match up best with your Orbs.
Hope this helps. If not at least it bumped your thread
Cheers,
