Shockwafe Ultra 9.2 SSE MAX

If money was not a factor then I'd probably look at the Sony Bravia Theatre Quad with the bigger of the two subwoofers. For the biggest sound for say a home theatre without going the AVR route, I'd take a look at the Nakamichi Shockwave Ultra 9.2. For me the Sonos has too many negatives such as no Passthrough ports or DTS support. The Q990F is excellent as well. I think RTINGS is the best site to look at reviews as they are objective and not subjective. Their best soundbars page is useful: https://www.rtings.com/soundbar/reviews/best/soundbar

I went from the Nakimichi 9.2.4 to the Samsung Q990D and it's an entirely different experience. The Q990D blew my Nakimichi out of the water even going down to 1 sub.

My 9.2.4 was bought new ~6 years ago for reference. Loved it, just wanted to see what all the hubbub was about with the 990D. And phew. At least for my living room and setup, it's very good.

Please do yourself some justice and research and investigate the Nakamichi Shockwafe or if possible the Dragon. In head to head comparison, in my home theater, the Shockwafe 9.2.4 atmos dwarfed the 990 and the sonos. In EVERY way. Period. My opinion as a sound engineer.

Nakamichi Shockwafe or Dragon if in the budget. Period. Anyone with another opinion just doesn't know any better. I've side by side compared them ALL, extensively! You will agree if you take the time to investigate on your own!

Honestly those prices I’d get 1 of the couple Vizio M series 5,1,2 or check out used. I got a crazy deal on a Nakamichi 9,2,4 and a 7.2.4. You can’t beat dual 8 or 10” subs on anything really.

The Nakamichi definitely hits harder on the low end, but the Bravia Quad setup really shines in terms of clarity and spatial sound. I was surprised how much difference it made, especially for Atmos content. The way it fills the room is just on another level, even with a tricky speaker layout.
