Looking for soundbar for this bedroom setup
What soundbar setup would be the best for watching movies mostly. It's a samsung TV (50 inch) which is installed. Space is around 45 inches in front of the TV.
Room size - 12x14 ft
Budget ~ upto 50/60k INR
What's the best that I can expect around this budget, should I go for the 20-30k range systems or the ones in the 60k range would really provide the true surround experience in this room.
Also, I read somewhere that the 5.1 channel systems have to used at 70-80% volume for all the channels to perform fully, is this really the case? Or is that related to the watts of the system. How would the tv being in that space affect the overall sound if using the q symphony system, or the soundbar being placed in front of the TV.
First time posting here,so sorry for violating any rules.
