Hi All, I've just set up my KEF PSW1000, only a budget sub but i just needed a small ammount of bass reinforcement. I was looking at the specs and it quotes a frequency responce of 38hz to 120hz. However i have tried a 33hz test tone on it and it plays rather loudly. Does this mean that the sub can play lower than 38hz? Or am i missunderstanding the specifications? Best Regards Chris Harris.
