We’ll never compromise audio for a bigger screen as you will regret it. Not wanting to move my left hand speaker closer to the wall is what stopped me from going with a 130” screen. Going from a 110” to a 120” screen was 7” wider and even having the speaker 7” closer to the wall affected the sound negatively. It is all a balancing act.
I just use phantom center and see no reason not too (I have owned centers before). If you sit in the middle the sound is 100% correct in the center and I like to watch movies by myself. People talk about comb filtering on movies with phantom center as the speakers are in mono for most speech but as a very picky audiophile (aren’t we all) I have no issues with phantom center. The center is really a benefit for people off axis more than anything.
On a side note I bought my house in Ohio for $95 a square foot…
revel’s 226be is a nice sounding slender speaker if you ever wanted more room but I think they lack dynamics/snap next to a good horn. I would keep the horn and rock the phantom center.
