Hi quite new to all this and need some help please. I have just got the kef kht5005 speaker package to go with a Denon avr2805 amp. I dont know how to set the psw2500 sub up. It has adjustments for input,crossover,phase and a switch for slope. In the limited instructions it talks about frequency crossovers so you can get the sub to intergrate with the speakers??? Im lost and to make it worse the amp has a microphone to run an auto setup and that just adds even more confussion into the equation. At the moment I feel that all the money I have spent is wasted as I dont know how to set everything up. Any one prepared to advise?
