@Matthew Montgomery Perfection is a myth, unfortunately. Nobody has a perfect room because it is unattainable. But, reliable and trustworthy rooms are attainable. The reality is that any amount of improvement is just that - improvement. If nothing else, at least put a 2x4ft panel up at each of your first reflection points and treat the front corners with bass traps. Wall panel thickness should be either 4in or 6in, whatever you can manage. Bass traps should be at least 6in, or a corner wedge covering the entire height of the walls, from floor to ceiling. Look at GIK for ideas.
