I'm looking to enhance my tv experience in a family room. It accordingly does not need to be a immersive home theater sound. The room is about 16x16 feet with high ceilings. I want to have a 5.1 setup and own a receiver. Being able to play music is important to me. Main speakers need to be bookshelf. I was thinking about the definitive tech procinema 600 since I acquired a pair of the 8020 towers which I love, however I became hesitant when it came to the driver size and the size of the room. Budget for the speakers is around 700. I don't need to necessarily get a sub with it, as I have an infinity entre sub (10" 150 watts) I could certainly use and don't have other plans for (I just assumed it was not that good). Any suggestions would be much appreciated.
