Best position for rear channel.

If the speaker is not made to be close to the wall it will not image right (i will not get into acustices here) You need to fins a spot where it images well just like the frount. ANother trick I have a similar romm and oput them about 8' high and that worked really well for sourounds.

The null spot is to the side of the listening chairs. I have to be closer to the rear speakers than the front so I can't go with a 360 degree arc, me in the middle equi-distant arrangement.Believe me I have tried every spot short of suspending them from the ceiling. I was hoping for a solution from someone with a similar system using CLS for rear speakers. The sound is very detailed and engulfing as it is with the speakers behind me, equally distanced to the side and rear wall as the front speakers are.Thanks to all.

Lacee,

I would recommend trying a 7.1 speaker set up. With two speakers directly to the sides of your primary listening position (+- 90 deg), and another two speakers spread apart in the rear of the room, behind your listening position (about +- 160 deg), you will get much better surround envelopment than using only two surround speakers.

You will need DPLIIx and /or Logic 7 to properly drive a 7.1 speaker system, since there are no 7.1 sources, but in my own experience 7.1 is well worth it.
