put the speakers ~6 ft from front wall.
keep speakers ~7 feet from each other (3 ft from each side wall) and toe them in towards you
move your seat ~7 ft from speakers (move in closer, midfield)
put a pair of subs on each side wall behind the seat...about ~3 to 4 ft behind...
If things still sound like sht, call vandersteen and tell him that his speakers suck in general...and get a better speaker.
With the current long‑wall placement, the sound is shallow, a bit lifeless, and the soundstage is poor.
