hi, i have an nec 61mp1 display, with a pioneer vsx 1014s receiver, marantz dv7000 dvd, snell LCR500's, b&w ds6 surrounds and b&w 601 rears, but no subwoofer can anyone suggest a suitable one? i was thinking of a mission 78as maybe? another question i have is, this is my first attempt at home cinema and i didn't really plan it, i just sort of fell into it! all this equipment apart from the dvd player came from friends selling me their equipment at what seemed like good prices, but i don't know if it will all work well together, particularly the speakers. the snells are 4ohms and need 200w the others are 8ohms and need about 100w. can i run them all off the pioneer which has 7 channels and 120w at 8ohms? could anyone explain impedances and watts etc. please?
