Am looking for speakers to put into a 18'x14' living room. The room goes into a dining room/kitchen: 7'x16' I want to set up a listening area in the living room with the speakers about 5'-6' away from listening position. Will this work in a room this size? I live in a basement suite and want to contain/minimize the sound going to the upstairs. Questions: What would be the choice of speakers for this setup? How much would the base extension of the speakers matter in sound going upstairs. I like good base, but don't want to have problems with the neighbours if I turn it up to a good listening volume; not that I like it overly loud. What would the difference be between floorstanders and bookshelf speakers? Things like: - soundstage - stereo imaging -sound quality I don't care if the sound fills the suite, just so it sounds good at the listening area.
