Where do I position 4 speakers for 3D stereo sound

My room is 22-15-8 feet. I have a pair of K-horns, and a pair of Lascalas. The K-horns are along the short wall facing outward using four foot false walls. The Lascalas are in the rear to provide a 3D effect. Both pairs are using separate Mark Levinson 334 amps. I am aware that these speakers are designed to be played loudly. However, when played at a low volume, they can create sound effortlessly, and without any distortion at all. My problem is how far back from the K-horns should the sweetspot be positioned,and where should the rear speakers be positioned
to provide the best 3D sound? If the sweetspot is ten feet from the K-horns, then all speakers will be equal distanced from the sweetspot. But is ten feet too close to the front speakers? If the sweetspot is moved back, will I be too close to the back speakers creating phase problems? In that case, should the rear speakers be reflected off the back wall, or side wall? With this in mind, the high frequencies from the tweeters will be lost? Does anybody have any ideas about this problem?

The best place you can position 4 speakers for "3d-Stereo sound is stack one pair on top of the other pair. Try the best you can to match the output levels. Remember, stereo is a 2 channel format. It never was meant to have more than 2 channels, nor any surround sound additions. The music is not recorded that way, and anything you get back there is not correct.
Additionally, every conceivable method of 2 channel surround sound has been done, and re-done, a hundred times. I guess you weren't around in the 70's when this was being tried the first time around, and led to the awful Quadraphonic being introduced, only to die a couple years later. Hafler circuits, ADC digital delay units, "ambience" processors. They've all been done to death.
If you want "Stereo" than you want 2 channel. If you want surround sound, then move over the the HT world where "more is better, and even more is even better". Soon they will have 48.1 systems with 48 amp channels and 48 speakers, with one for the center, of course. For that "movie theater" sound. Yecchhh.
