tldr; Best value Samsung Atmos bar. 5.1.2 without wireless rears, but add Samsung rears later. Punchy sound for the price.

+13 pts“It seems that the snobs followed you here OP, lol. A lot of salty responses here. On topic: check the q800 series from Samsung or see if they have the q990 series on sale, they often have last year's model on a deep discount. I have the Q800C and really like it”

+2 pts“No I would avoid, Q800 is designed to be used with subwoofer, you will get a a very flat sound without. I live in a apartment that does not have thick walls too, and the sub is perfect, you can add some dirt cheap feet like this [https://www.amazon.fr/gp/product/B0047T6WXY/ref=ppx\_od\_dt\_b\_asin\_title\_s00?ie=UTF8&psc=1](https://www.amazon.fr/gp/product/B0047T6WXY/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1) and adjust bass to -1/-2/-3 if needed, the result will remain infinitely better than without a subwoofer at all.”

Best praise vs top criticism for Sonos Arc Ultra
Best Praise
+21 pts“I can say the same. Currently own Arc Ultra + Sub 4 + Era 300s. Previously owned Q990D and Q990B. The Samsung is amazing value at its price, but the Sonos set just sounds cleaner and gets to high volumes without straining. It doesn’t ever feel harsh or overworked. I would say for its money - Sonos is 3 to 4 times more expensive but is NOT 3-4 times better, but there is a difference in quality for price. Both are terrific - and get what your budget allows - would you agree?”
r/Soundbars
ViewTop Criticism
+18 pts“My issue with the Sonos arc ultra is that the entire setup with the 300’s and gen 4 sub costs 3x what you can get the 990D for and it is in no way 3x better. There are some things the 990 even does better. The Sonos is definitely better for music tho”
