Re: Something old is young again, introducing the Sierra-1 V2!!!
You can use the S1 V2 as a center, either standing vertically or horizontally.
Otherwise, the Ascend speakers are all very similar in tonality/voicing, so any would work. That said, if you watch a lot of movies, I'd buy the best one you can afford (to minimize the possibility of upgrading down the line/FOMO).
