they are placed in an irregular room with openings
i do not know how to place speakers!!!!
they are 5 foot from the front wall and about 6 foot apart
they were ok but the soundstage seems to shift to the left

Try placing a mirror on the wall at the same hight as the tweeters. Sit in your listening position and have a friend move the mirror along the wall until you can see the tweeter from your seat. Mark the spot and do the other wall. These are the first order reflections. Place something at that spot to absorb the reflections-like a tapistry or some other acoustic treatment. This will go along way to cleaning up reflections and will improve presence, soundstage and frequency tone. For even better results, continue to move the mirror along the wall until you see the other tweeter-this is the second relection. Treat it the same way. Good luck.
