I have all Polk gear which I've had for years. It's older stuff (rt1000ps, f/x500 surrounds, center, ). I bought a pair of rt f/x (older rear surround speakers) that have a bipole/dipole setting. I have the f/x500 on the side walls facing the couch (per instructions) and set on dipole. I suspect I set the rt f/x speakers in the rear at bipole. Any opinions on this would be appreciated. Oh, I'm running a Denon 2807 and have used the Audyssey MultiEQ to tune the room (to six positions per instructions). The sound field is pretty expansive but I'm trying to understand a bit more how it works and if there are advantages to switching those speakers in or out of phase. Thanks.

and ignore any reference to the rear speakers...I need to update my blog.
