HW-Q60C (Q60C)

This is a good deal OP, it is the Q60C model with a Sams model code. It has pretty basic Atmos but will definitely be a solid upgrade on the TV speakers. And if you don’t like it, you can return it!

It plays Atmos but down-mixes it into stereo. So you won’t get the height you would on a system with upfiring speakers.

Samsung has a much stronger history of soundbars and are among the best with the 990 series. I myself had the Q600Cwith the 9200s surrounds and it was great and currently have the Q60C in my living room. The Onn 5.1.2 is definitely good at its $199 price but I would trust Samsung more if you are willing to pay a little bit more

I originally bought the 600c and it was good, but the newer model , qs700f has smart things app support, direct Spotify and WiFi support, and the bass sounds better. It has much more control of the sound with the app and remote too.

The Q800D would work great for you. I had the QN600C in our bedroom for a bit and it was awesome.

Top picks (all true Atmos + wireless sub, ≤ 42”) • Vizio M-Series Elevate M512e-K6 (41.38”) — 5.1.2 with included rears + up-firing in the bar. Killer immersion per dollar.  • Samsung HW-Q600C (40.6”) — 3.1.2 with up-firing drivers, eARC, and works with Samsung Q-Symphony (your Q90T supports Q-Symphony with compatible bars). Great if you want the TV+bar to play together.  • Polk Signa S4 (41.2”) — 3.1.2 with two dedicated up-firing heights; simple, slim, and dialog-friendly.  • LG S75Q (35.1”) — Compact 3.1.2 with upward-firing height channels, HDMI eARC, Dolby Vision passthrough.  • Bose Smart Soundbar 600 (27.3”) + Bass Module 500 — Small bar with 2 up-firing drivers; add the sub for real low-end. (Sub is separate.)

If dialogue clarity is the main goal, go for something with a dedicated center channel and a mode that boosts voices. Between the two you mentioned, the Samsung HW-Q600C is the better pick. It’s a 3.1.2 setup with a dedicated center speaker, Samsung’s Adaptive Sound feature that makes speech easier to hear, and it will work perfectly fine over ARC even without eARC. The HW-B750D is okay but not as clear or well-tuned for voices. Other options worth checking out in your budget are the Sony HT-G700, Yamaha SR-C30A or SR-B30A, and the Polk Signa S4, all of which do a great job with dialogue. If you go with the Q600C, make sure Adaptive Sound is turned on and, if needed, increase the center channel level a bit to make voices stand out even more.

I just bought Samsung and for that category, it's an immersive.

Its good value for money especially if you get the rear speakers. Not so good if you're gonna be using it mainly for music. FWIW I recently did an analysis on reddit data on soundbars. Basically ranked them by aggregated sentiment. Maybe you'll find the results helpful.
