Samsung HW-Q990D vs Sonos Arc Ultra
Verdict: The Samsung HW-Q990D wins for users wanting complete 11.1.4 surround immediately with strong bass from its included subwoofer and rears (RTINGS measured 656W output). The Sonos Arc Ultra leads in build quality and ecosystem flexibility but requires separate purchases for sub and rears to match surround capability (Wirecutter notes higher expansion cost). Both support Dolby Atmos and DTS:X but the Q990D edges value for dedicated home theater setups.
Winner: Samsung HW-Q990D
Samsung HW-Q990D: 8.2/10
Sonos Arc Ultra: 8.5/10
