I only have neighbors above me. I live on the end so nothing on one side and a daycare on the other. I dont see them getting angry. I'm trying to decide if I should buy that used sub or something new. I dont know if the risk is worth trying to save money to get a "better" sub. I'm also not sure about the reciever if I will end up disappointed with the sony or not. I really wanted a yamaha or denon but I couldnt find one with 3D channels under 500.
