My Sonos system does a clever room analysis via the phone app when you first set it up so as to balance speaker output and tonal response to suit the room.
It’s clever stuff and does seem to make a difference.
Back in the day I had an Onkyo surround sound receiver which had a mic you plugged in to do the same thing, but tech has advanced so I think the Sonos does it better.
Obviously it won’t fix a very echoey room with lots of hard surfaces, but I think it does the job in many rooms.
My wife, son and I went to see Frank Zappa’s son Dweezle’s band at Warwick university. The sound was perfect. No noticible reflections. A couple of years later we saw him at Birmingham Town Hall, a Victorian concert hall. Same or very similar music played and it sounded terrible. I refused to see him there when he returned. Such a waste of fine musicianship.
Not really designed for amplified rock music, presumably. Queen Victoria would probably not have been a Zappa fan. 
There’s a lot of skill to mixing a band in a difficult room, and surprisingly some sound techs don’t seem to have it.
Sydney Opera House Concert Hall now boasts a sound experience to match its iconic exterior architecture. Even empty seats are taken into acount!
Doesn’t it know? 
Not a very Smart tv then? 
The first time I was there, they were still building it.
The second time I was there. they were still building it.
It should be good by now then.
I thought I had a Smart TV 
, but clearly not.
I believe was very fond of Catholic girls.

I prefer to listen with my Blutooth headphones. The TV has BT built in but I also have a Sony BT adaptor which provides Atmos sound. It allows me to use BT even when the loudspeakers are in use. (WLA-NS7 | Wireless Transmitter | Sony United Kingdom) . I often use them even when Ewa is watching and using the speakers as she needs higher volume than I am comfortable with. I find the headphones particularly useful if I am listening to French dialogue.
The voice of experience!
A lot of it is down to where you place the PA speakers. The best engineers always examine the room carefully before deciding on the most appropriate locations.

Met the great man leaving after his excellent gig at Manchester’s Free Trade Hall, I think he autographed all the breasts of the women in our party.
Had seen him a few year’s earlier at a very different (electronic chamber music) gig at the Manchester Opera House. Don’t recall any breasts being autographed there. But of course, it was the Opera House…
Joe’s Garage is noted for its use of xenochrony. Bet you didn’t know that 
Electronic chamber music sounds fun. I enjoyed Switched On Bach.
Didn’t get along to enough gigs as a young man. I thought it better to spend money on records - a mistake.
I’ve never knowingly ever heard any of Zappa’s music, but a friend would sometimes repeat some of the lyrics at appropriate times, and that one popped out of my memory.
You could try Jewish Princess 
My wife might object. 
Not going to quote any lines from that song 
I love this song FZ performed with his daughter Moon-Unit.
From the website -
The song pokes fun at Valley Girl talk, which was a fad in the early 80s that began in California among teenage girls. It also pokes fun at what Frank believed were spoiled rich girls from the San Fernando Valley in California.
Frank had stressed that the song wasn’t a happy one and he disliked the San Fernando Valley, calling it “a most depressing place”.
