Hi guys, I live in a bilevel house and top floor is an open floorplan with vaulted ceilings. The whole area is the living room, dining room, and kitchen. I am looking to start with the fronts and center speakers first. I have a Yamaha v673 receiver and a small polk sub. Wife hates bass so sub is no big deal for now. My budget is $600 for the 3 speakers, if I just have to start with just right and left then so be it. I have a large entertainment center where I have infinity bookshelf speakers up on the top shelf. I would prefer to do floor standing speakers and the wife would like the smallest invisible speakers possible. I am open to bookshelf speakers if the sound quality would be similar to the floor standing models but they would probably have to lay horizontal. Thanks for the suggestions!
