I have no sub output on my Pioneer VSX-9300 and i was told i need a powerd sub that has a high pass filter..with speaker inputs so i can run the speakers in to it then out the back of it inot the AMp unit...thus giving me the lows i need with out having to buy a whole new setup. Any reccomendations on this type of sub..or aanother way to do this with my existing non powerd sub? Also canb someone reccomend a good set of speakers i need 4 for the front and 2 the rear. Aslo sorry for my total lack of understanding of this type of setup...i am totally new to owning any kind of real HT setup so please forgive me Thanks! Dave A.
