Hi Guys, I have a 2.1 system I want to expand out. room details: pair of w22s about 6 feet apart for fronts. Room: 22 x 14, TV against long wall, listening position pushed AGAINST other back wall. A 350v2 sub sits in back corner. Amp/reciever: Sherwood Newcastle r-972. Ceiling is 8 foot in back, rises to about 16' over TV.
I want to got to 5.1, wish I could go to 7.1, but the fact that my seating position is flush against the back wall is causing me all sorts of issues. Ideally, I'd like to mount the bi-pole QS4's on back wall, but what would having the wall so close to me do to sound? And where would I position them? ~Note that they have to be about nine feet apart (back window) and also recall that ceiling sloops up from them...
Every diagram I've ever seen (using bipole rears) shows those speakers at least three feet behind the seating positon. Does the rear wall force me to consider something else, direct radiating speakers mounted to side walls perhaps? Thank you in advance!

If you are going 5.1, the surrounds should be placed on the side, not at the back. Can mount 2 QS4 on side? (slightly to the back, 2-3' above ear level).

As Eric mentions, you want to place them to the side of the listening area, preferably 2-3ft above your ears or higher. The rear tweeter will then direct sound off the back wall, simulating a 7.1 setup.

well - I'd thought 5.1 "rears" could go on back wall. please see bottom illustration at : http://www.polkaudio.com/education/tech_article.php?id=27Also, this site : http://www.technosound.co.uk/nav.php?pageid=hcg_settingup mentions: "With the seating against the rear wall, bipolar speakers must be placed on the rear wall half way between the seating & the side walls" I'm hesitate to mount things to side wall because they would be so far away; room is 22 feet wide - and one of the side walls has our fireplace, so my wife would veto it... Thanks for the feedback so far!

Side placement of the QS4 is recommended but there is nothing wrong on mounting them on the back wall. This is even mentioned in the QS series manual.

Since you must use the back wall, spread them as far apart as possible. The QS series is amazing at generating envelopping sound even in less than ideal situations (which probably half the installationsa are because of physical or wife constraints! ).

As the others said I would not worry too much about it, the side walls would be best but if they are on the back wall they will still be very good and (obviously) a huge improvement over nothing.
The height can vary, 2 - 3 feet above your ears seems ideal. Mine are about 16" above to the bottom of the speaker and they sound great.

My rooms is the same size as yours (within a foot or so each way). I have m80's vp150, 2 QS8's and an EP500. I also have my TV against the long wall and my couch against the opposite wall. I was unable to place my QS8's on the side walls because it is open on one side (into the kitchen) and there is a brick fireplace on the other. As a result, I mounted my QS8's on the back wall, separated almost as far as possible and about 6 feet off the ground. They are mounted flush to the wall with the supplied T brackets. The QS8's sound amazing the way they are, an indicator that they are very forgiving for placement. Before I purchased my axioms I auditioned a similar setup at someones house that I met on the boards. They had the QS8's on stands at the side of the couch. In my opinion, the QS8's sound better up higher on the back wall than they did on the sides mounted on stands. Here is a picture of my surrounds: Please forgive the poor quality, the picture was taken with my iPhone.

Ax, welcome. Keep in mind that even if the surround speakers in a 5.1 setup are mounted on the back wall, they're still side surrounds. So, mounting about 2-3' above ear level and spread widely(say at least 10')to give primarily a side effect should work well.

Enjoy the music, not the equipment.

thanks SO, SO much everyone. and picture was perfect. Exactly the same as my room - even down to being open to our kitchens. Of course all your equipment is a bit scaled up from mine (I hope your foundation is bolted down) but geometry is same and I'm glad to hear that you're getting good results...
~ you have the QS8's about 12" from side walls? is that right? Also, what does the person sitting in your side chair hear? My wife would be in that general area - does the down-woofer of the QS8 bother/deafen the person in that area when system's been optimized for the center of couch a good eight feet away?
