If I understand your question, you are looking for something very unusual. Typically we look for the soundstage to begin at or behind the speakers… like at a concert. The stage, is where the sound comes from. The mark of a great system, in part, is it being laid back with a deep / wide sound stage.
Some speakers can be “forward” typically having a shallow sound stage… typically this is a criticism of the system because it is not reproducing natural sound.
There is a few home audio speaker systems that are are designed not so much to do the sound-staging.. but to produce a wall of sound. The ones I remember hearing were six or seven feet high, with tweeters in the middle and mid range above and below then further out woofers above and below. I don’t remember names.
i would recommend trying your system against the short wall. Making sure there is nothing taller than an amp on the floor… equipment racks typically interfere with sound staging.
It would be really helpful to see your system in its current form. There is a place for photos along with your equipment.
