I suggest using CARA to anaylze the room with respect to woofer placement. Some rooms respond best to symmetrical placements, others to asymmetrical placements. It is entirely dependent on the room shape and the intended listening area.

In any case, damping is very important, as much or more than placement. Framed drywall construction helps damp room modes because the walls flex; Rooms with rigid walls (like concrete basements) or those with raised hardwood floors over crawlspaces have their own sets of problems and probably should be dealt with using additional treatment. Bracing and damping of hardwood floors is usually important, bass traps are usually required for concrete basements.
