When you are looking for a home audio system, music and television sound are usually the priority. While home theater systems are increasingly popular in many Indian homes, you may be better served with a stereo system or a hifi music system set up to complement your TV setup.
This would result in a much improved sound experience than your TV speakers allow and also a great music experience when you are playing music off your smartphone. It is also likely to be much more affordable than an elaborate home theater setup.
A basic stereo music system would consist of a pair of bookshelf or tower speakers, combined with a more basic amplifier or audio receiver. While this receiver may not include video connectivity and support, it should have Bluetooth support either via the amplifier or with the use of an external bluetooth receiver.
