Hooking up a home theatre speaker system without drilling holes in my wall?

What's the best position for Mission M7DS bipole surround speakers in 5.1 system?

• I have to rearrange my living room which means changing my home theatre speaker placement. What's the best positioning for the Mission M7DS bipole surround speakers in a 5.1 system? I'll be placing them high up on the wall close to the ceiling, (Mission recommends the speakers are therefore upturned to avoid sound echoing back from the ceiling) but the question is: should I place these two speakers on the side wall or on the rear wall? How far should the speakers be from the corner so there's no issue (if any) of the sound echoing back and cancelling? If they're going on the rear walls, I'd like to place them as far apart as possible (if that's the recommended way) but not too close to the corner if that produces any sound cancellation from echoes. Any ideas, please let me know because I'd like to get it right first time so I don't have to experiment with different positions and drill holes everywhere that will annoy the missus :) The room is 2.8 metres wide and the sitting position is with the sofa flush against the rear wall. Thanks.

• Answer:

  Dolby does not have a standard for dipole speakers but THX lucas films does so I would recommend researching the THX standard......sometimes when we have a less than ideal placement option we have to experiment to see what sounds best outside of any standard...so if you can experiment with different placement options... you may have to leave it is one position for a month or two before you become accustom to the sound and its limitations and then try another position for a month experiment with various movies and music you are familiar with until you find the most pleasing effect with the widest amount of movies and music....you may have to adjust settings several times and you may not be able to use the built in analyzer either it may have to be tweaked by ear....and using a sound meter...but just generally speaking the closer the speaker is to any reflective surface the ceiling the side wall the rear wall the greater the risk of harmful reflections but compromises have to be made between what looks best and sounds best and whats practical for our particular room and life style...
