What's the Best Upgrade for TV Audio Under Rs. 15,000?

If we're talking about mid-range families, then honestly, spending another Rs.15,000 on a soundbar or speaker setup may not feel worth it after already buying a TV. I feel TV brands should focus more on improving the built-in sound quality. But at the same time, not everyone is that budget-conscious. There are plenty of premium users who wouldn't mind spending extra for a better audio experience. So if someone really wants better audio, then a soundbar is probably the simplest option compared to dealing with multiple speakers and wires.
