Dr. Spec can I get a follow up?

Hey there. You had mentioned in another thread, to another user, that if you have the FXI's mounted on the back wall to have the woofer's pointing inward...

It's kind of been in the back of my mind ever since I read it and was just wondering if I could get an explanation of your statement.

I've recently moved my FXI30's to my back wall for experimentation purposes. I'm wondering what advantages having the woofers facing inward would offer.

I currently have them set to the bipole setting, mounted about 2.5' above the head on the back wall, but the woofers are most certainly pointing away. In my mind I thought it was aiding the dispersion, made the sounds seem to come from "outside" the speaker on some scenes.

If I'm correct, when you have them mounted on the sides you want the woofer pointed towards the television, which is, in a sense, away from the viewer.

I'm just looking to educate myself further so I'd appreciate any and all insight. Thanks!

I'm not sure I ever specifically referred to the direction the woofers were pointing.

I think I said that there was a left and a right speaker, and that the left/right orientation is correct when you are facing the front of the room/TV.

I honestly don't know which way the woofer points in the FXi50 when the speakers are correctly oriented in this fashion since I own f/x1000's and they have dual woofers.

If you mount them directly to either side, Polk recommends the dipole setting.

If you mount them to the rear of the listening area, Polk recommends the bipole setting.

Hope this helps and I'm sorry if I confused you with my other post.

Well, I found the quote:

"Try bipole switch at the rear and dipole switch at the sides. Also, in the rear try to arrange it so the midrange driver faces toward the listener."

In context, it seems you were referring to a 6.1/7.1 setup.

I tend to confuse myself quite often...

danger boy

this works for me... FX30's mounted to on the side rear wall. 2 1/2 feet above my listening posting.. running in bipole. dipole sounded off to me. sounds great. even tho i am only 5.1 this gives me the "effect" of having a rear center.

The best thing you can do is try both areas, and both settings. bipole, dipole.

That is correct.

In a 6.1/7.1 set-up, you want to run the rear(s) in a direct radiating fashion, whether they are monopole or a bipole design. With a bipole design, all I was suggesting was to have the midrange driver of the rear speaker(s) face toward the listener for a more discrete effect. Sorry if I confused you with that.

For a conventional 5.1 set-up with bipole speakers, follow Polk's recommendation and make sure they are placed properly with respect to left and right.
