I have a new 7.1 Pioneer Receiver and Polk speakers in a 5.1 setup. Here is what I have going:
Front: Polk RC85i
Rear: Polk RC80i
Center: Polk CS20
Sub: Polk PSW505
Receiver: Pioneer VSX-1020-K
Everything works great except the sub. I am on my second sub from Amazon and I am still getting the same problem. I am hooking it up to the "Sub Out" in the back of the receiver and the "LFE" input in the sub. I get very little to nothing out of the speaker. I've tried everything and even my neighbors who have HT systems have helped and cannot figure out what is going on. I've tried every setting on the receiver (sub on, sub off, sub plus, etc) and get the same thing. I tried adjusting the "LFE" setting on the receiver and that doesn't work. I don't want to return another sub to Amazon because I know it has to be something I'm missing. I spoke to Polk and it seems as if they do not know the problem either.
Thanks in advance for your help.
