I bought this unit from a Federal Employee Activities Association website. I am upgrading from my LG SJ9, which I absolutely adored. It was perfect for my living arrangement. Before that I had an Onkyo HT5800 system which was great but I got tired of the wiring. I bought the Sony Z9F and it just didn't playback older soundtracks from older shows and movies I enjoyed. So I figured I'd get back to my love for LG and pairing my 65" B7A, which I just upgraded from my 55".
Anyway, for my living situation which is about a 15ft X 25ft living space (smallish one bed, studioish apt) I got my couch about 4 feet away and still hear a great immersive sound when Dolby Atmos, and even DTS Tru HD are played. I wanted to test the bar alone before I made any decision to add the optional rear LG SPK8-S speakers. The sound is crisp, and the ability to changed the height levels is awesome. Because my apt is living area is 15ft wide, the sound bounces off the walls to the left and right. I watched Game of Thrones which has an Atmos playback option. Oh man, the voices and the rumble of the Battle against the white walkers was insane, every clink, and sounds of swords. I threw on John Wick 2, as well as Saving Private Ryan, and it was like I was there on D-Day, and riding along side John Wick in his muscle car. So I decided to purchase the rear speakers and it made the sound so much more immersive, 360 degree sound all around me, especially with Game of Thrones, which for me would be my reference for this tech.
All in all its great spacial sound, however, I feel like a lot people just expect it to work. But you have to make sure the room you have it in works for the device. You also need to calibrate your Xbox One S, One X, or you 4K UHD player to pass atmos/dtx which usually consists of changing audio settings to "uncompressed bitstream" or "enhanced." Other formats like DD+, DD HD, DTS tru HD, all performed very well also. Older shows and movies sounded very nice do to some upscaling.
I would advise if you have a bigger room than my small shack, get the SK10Y, itll back a bigger punch than this system. Another system id advised to get is the Sony HTS5000, my cousin has this and goodness, 7.1.2, and it sounds ridiculous, but he has a huge living room. Anyway, I wish I could invite you all over to check out this set up but 5.1.2 sounds fantastic, getting the rear speakers to enhance to a 7.1.2 makes its your own personal theater. it really is worth the money, and the patience to calibrate it.
