dipole surrounds

I have several questions regarding dipoles as they relate to surrounds.

Are dipoles forgiving in regards to placement? Can one dipole be mounted in a corner while the other is mounted on a flat wall on the other side?

How are dipoles installed. Do they come with some sort of system so that mounting them on the wall is simple.

Is it okay to mount them higher than one would mount more standard speakers.....ie. say above a door.

Thanks,
Mike

    Hey Mike, what speakers do you have in mind? The rule of thumb for surrounds is to mount them 2' higher then the seating height. As far as placement goes, a lot of it is governed by the room layout. Sometimes you just don't have many options. As far as mounting goes, you can always pick up mounting brackets. How big & heavy are the speakers?

    Sounds like you have a nice little project going on there!

    Cheers,
    Phil

    If you are using dipoles (NOT the same as bipole/dipole speakers set to the bipole setting), then you need to place them directly to the sides of your listening position to create the diffuse effect at your listening position. I spoke with Polk about the placement of the Fxi50s, and they said it would be best to mount them so that the top of the speakers were at 6' directly to the sides of my listening position.

    I've done this and it works great.

    I have my FXiA6 (dipole or bipole) on the side walls behind seating area, about 2 feet from the back wall, about 2 feet above ear-level of seating position. They are set to bipole. (This setup seems to work pretty well, due unfortunately on wall directly to the side of the seating position is the door).

    Here is a picture from polk's site:

    The purpose of dipoles is to create that null area around the listener so you can't pinpoint the speaker location and the sound seems to come from all around you. A placement that isn't symmetrical will break up this effect.

    The Polk FXi A6 speakers with their bipole/dipole feature, shouldn't the speaker be set to dipole when the speakers are on the side walls, and set to bipole when placed on the back wall? I saw some placement photos from Crutchfield and other sources about this.

    I just noticed these replies now as this thread has not shown up in my new posts and I have made a decision to go another route.

    I have made a compromise in placement and have decided to go with in-ceiling speakers (althogh which ones haven't been selected yet). Not really ideal with placement either but feel like it is about the best I can do.

    Phil...this project doesn't seem to end nor does it seem to have an end in sight....ugh been without the system for over a year now and am getting pretty fed up to be honest.

    Thanks to all for the replies and I apologize for not chiming in sooner.

    Merry Christmas to all! (or whatever you may or may not celebrate)

    Regards,
    Mike

    Mick, I realize that you are now going another route....but I did want to share that the Polk surrounds (mine are LS f/x) have a nice keyhole slot where you can hank them much like a picture or cabinet. The speaker nuts are recessed, and the unit looks quite good on the wall. Different Polk surrounds use slightly different versions of the same. The big f/x 1000 have two sets of metal mounting brackets. Good luck on your new project. Piper
