I just moved in into a small 1 bed room apartment for school, and I want to have a surround sound system. I know any home theater is not a good idea if you live in an apartment, but I really want one and am willing to compromise. The main issue is that the walls are not insulated well especially in the living room area. For example I can hear my neighbor shouting cause he plays a lot COD. My other neighbor doesn't really make to much noise. I am looking for some Polk speakers to match a Onkyo 608 to utilize its Audessey to be able experience the surround sounds dynamics at low volumes. I was looking at a pair of tsi200 for the fronts and tsi100's for the rears and a cs10 for the center. For the sub i would use the Polk Psw111. I am wondering if these speakers would be too loud for my apartment.Of course I would be considerate and not play it at loud at night. Should I downgrade the tsi200's to tsi100's or does the size of the speaker even determine the loudness?
