A friend of mine wants to buy a 2.1 system for listening to music(mostly rock/metal) in his living room which is about 11x13 ft. He'll also be okay with a soundbar, if the sound is exceptionally good, although his preference will still be a 2.1 system. His budget is between 25-30k. Since I only know about home theaters, I need help from you guys on this. Thanks in advance.
