You can use other brand upfiring speakers if you can find some that fits and looks good enough. I would save to something like KEF Q50a or R50 if they are on sale where you live. One option would be on-ceiling speakers though. But more work with hiding the wires and likely needs to be compact sized.Choosing blind is in fact the biggest drawback, especially when I'm considering a long term purchase.
Ultimately, I have to rely on what I read and view on the internet.
The 3050i package does seem to be much more balanced overall. Great system at a good price.
I was initially considering the Jamo because they do look great and because of their atmos speakers arrangements, which is very clever.
The Q-Acoustics solution is in-ceiling speakers, which I understand to be the best atmos solution, but my wife isn't been very keen to the idea of making holes in the ceiling of the living room.
He lives in Portugal.Since you are considering the SVS 2000 I would personally check out B.K. Electronics as for the same money you could have two P12-300 with either a front facing or down facing 12” subwoofer. For room frequency two are always better than one plus these are also very musical.
