I think it's funny and interesting that when I was hooking up my Klipsch SW to my new Marantz SR 7007 I discovered there is no deciated LFE from the SW, which I knew, Just a left and right cable with RCA's. Then a dedicated LFE SW out on the Marantz. Not knowing how to deal with this I called Crutchfield and inquired about this. They are always very easy to deal with on the phone. The fellow I spoke with did some quick in service learning for me. Didn't realize that a SW is really only a mono connection. So he had me connect to the SW1 and then just dangle the one RCA. So just thought to mention, any ideas about any of this?
