The back surround location shown will work, but it'd be better to increase the separation between the side and back surrounds by moving the sides up a foot or two and rears back to the extent possible.

The speakers that you'll use are a bit smaller than usually suggested, but with a good sub handling the bass, should give an enjoyable effect. Keep in mind that your room doesn't have to be "filled" with sound at a high level. The requirement is just to have an adequate level at your listening position.

Thanks john.

I do have the flexibilty of moving the 5.1's up about 1.5'

I'm just afraid they would be ahead of my listening area at that point. Perhaps i could toe them in modestly?

If possible I would still consider spending the extra $160 per pair and get QS 4's for the side surrounds. If you went with this pair from the outlet you could possible get them even cheaper with a successful bid:

At worst, the buy it now price is only $116 over the price of two M0's. The QS speakers are truly great speakers and should be considered as an alternative if at all possible as they are definitely worth the extra coin.

Your diagram presently shows them about at the back edge of the couch. Moving them about 1.5' forward would only be at most a foot in front of your ears, and wouldn't require any toe-in. Furthermore, the couch itself could presumably also be moved about a foot forward.

Edit: I should add that I do agree with David and others that if at all possible you should make use of the QSs.

I'm really confused.

Do you already own the speakers (and you're just looking for comment on placement) or are you still in the purchase process for any of them?

I really wouldn't consider putting "on wall" speakers "between the studs" or "angling" them. It's not going to look good, and you might actually make them sound worse.

If you're really set on 7.1 in that room, I'd put the rear speakers actually BEHIND the couch and firing forward. I don't know what is off the chart on the upper left. I'd definitely put one of them in that 42" high wall to the left of the stairs - maybe just do 6.1 with that position.

I think you're going to get truly nasty early reflections from both the left front and right rear speakers as drawn.

I'd very strongly urge you to just do 5.1 with the QS surrounds in that room.

Personally I do not think there is enough seperation from side surrounds to the rear channels even if the sides are pushed ahead a foot or so. The effects with direct radiating speakers are still going to feel like they are coming from the sides and not from behind as intended, not much added to the experience for the cost of 2 more speakers and wiring, IMO. I would do away with 7.1 and stick with 5.1 with the side surrounds in the present location.


Pushing smaller speakers to equal the output of larger speakers could strain them and make them sound bad as they are not designed to push loudness levels, not the I think there will be a problem with M2/M0 scenario, just pointing out that pushing a smaller speaker to levels it can't reach due to physical constraints causes bad things to happen. I have not heard the M0's so I can not really say what the marriage of M2/M0 will sound like.

I suspect we have WAF involved in this situation. wink

WAF does play a part, but these are older "bookshelf" type M0's which i've owned for a while, which is why i was really looking for input on placement rather than equipment suggestions. The wiring for 7.1 is not a problem as the house is currently under construction, but it sounds like i may not get any real benefit from 7.1 with the constraints I have.

Maybe i will use the second set of m0's as rears for the kids' set up in the basement

Thanks for all your suggestions. With the 5.1 and 7.1 speakers so close together, tomtuttle's suggestion of a 6.1 using the 42" high rear wall seems to be the best bet. It will provide enough seperation to feel more "surroundy" than trying to jam two speakers into sub optimal locations.

Thanks again to everyone.

Can't ssem to edit my posts for some reason. Decided that I could still do 7.1 if I chnage to location of rear speakers. There is a stair railing between the right rear and the couch, but shoudl not inhibit the sound too much.
