I went over to a friend's house last night and listened to his home theater system. It was really impressive. He had M&K speakers. I currently have Polk rt25i speakers and a SVS sub. I do like sound of my SVS better than his M&K but the sound of the M&K speakers was great. I know the M&K are more expensive. I would like to know how much difference the room makes. My speakers are located in our great room. The room is 20x18 with 12 foot ceilings. The back and the side opens up into another room. His was in a bonus room that was made into a home theater. The sound was just more enveloping in there. Is it possible that I do not have enough sound aka small speakers or something for the room of the size that I have? I need some info from some of you guys that are more knowledgeable than me. Also he had a really nice yamaha reciever. I have a Onkyo 595. Thanks!!!!
