My current setup is:
- Arc
- 2x One SL
- SUB gen 4
It’s a big room with an 85 inch TV and I love the sound.

I mostly use it for Dolby Atmos movies and would like to get the best quality I can.

Should I invest in adding 2 more speakers? Is the difference noticeable? What speaker do you recommend?

If i add more, should I use Sonosequencr?

Thanks!!
