I have a 7 yr old Philips Soundbar with an external Subwoofer which costed me about 25k when I bought it . The Tv sound comes nowhere close to the Soundbar, and even for Music it's amazing , i.ve even used it for some parties and it's been great , especially with the external Subwoofer. I would highly recommend a soundbar with an External subwoofer. Doesn't have to be a highly expensive one, I'm quite happy with how much value for money I've got from it.
I also have a Denon Soundbar with an inbuilt Subwoofer for my other TV which I recently bought for 15k which is also quite good and much better than the standard TV speaker, but I prefer my Philips one for some reason.
