Recently bought the soundbar Samsung Sound+ HW-MS6501 . Its a 3.0 channel soundbar. I bought this after long research and audition including JBL, yamaha, LG, sony and other samsung soundbars. This specific model hit all of my checkmarks. It sounds excellent for both music and movies. I feel no need of separate sub-woofer in my 16*10 room. It producing enough LFE in my room.
FYI, its a 2017 model. Getting this one in 2019 is very hard for me. Thankfully some stocks still available in Reliance digital , but curved model. However grabbed one and trust me its worth
Its length ~40" inch that matched my 55" Sony tv.
