i finally received the package.....and was able to connect all the components....yamaha RZ1 receiver, mitsubishi 62 in 1080p tv and oppo digital player using 16 guage speaker wire and monster sub wire....and was greatly disappointed !!!!!!!!!i was expecting that WOW but never got it .....it sounded no different than the energy encore that i replaced.....not sure if i am doing everything right........i don't yet have the 4 ohms receiver but the axiom guys told me repeatedly that the yamaha receiver was more then enough....i do have another 20 dyas or so to make up my mind..any suggestions are welcome
