You need a good sub-woofer. Nearly all consumer speakers just don't have the displacement needed to play cleanly at subjectively realistic sound levels when fed full-range signals.
Probably placement after that - a good starting point for main speakers is the greater of four feet and half the distance to the listener from the front wall. More than 1130 / 4 / sub-woofer cross-over feet out is needed to avoid the SBIR null (ex: 1130 / 4 / 80Hz = 3.5' which you might round up to five feet).
A few feet from side-walls is good, five feet is better. The listener just far enough away to get out of the drivers' near field for proper integratation (an 8' equallateral triangle is often a good starting point) and at least 4' off the back-wall is good. Minor adjustments fore/aft and left/right will make a big difference in what you here of your standing waves.
Speakers would be next.
