I have bad experience with Samsung - HW-Q990B 11.1.4ch. After 9 months, the soundbar automatically adjust volume to 100%, there was a problem with Internal on top controls. Good thing its still under warranty and since Samsung was unable to fix due to parts availability, they refunded me thru BestBuy credit of same amount i purchased it 9 month ago.
I went to bestbuy and replaced it with Nakamichi - Shockwafe 7.1.4Ch 850W Soundbar System with 10” Wireless Subwoofer, Dolby Atmos, eARC and SSE MAX. As soon as i received the unit, tested it overnight and returned it back the next day. Sound quality is so BADDDD. Day and night vs Samsung.
Bestbuy credited me back and after a few days of research, i ended buying Polk Audio Magnifi Max AX SR 7.1.2. Was so happy with this one, better than the Samsung IMHO Sound quality wise, the Samsung has more features though. But im more to sound quality than features
I also have the VIZIO - 5.1.2-Channel M-Series Premium Sound Bar with Wireless Subwoofer, Dolby Atmos at my other TV which is performing really well Soundwise
Not sure if these two are available dyan sa pinas but if it is, its something worth to audition
