Room is way too bright.

"I keep hearing about this"first point of reflection." What exactly is that?"

Did you do any online research at all?

There is a ton of information on this subject at your fingertips, yet you seem completely ignorant of even the basics.

I suggest that you Google "first reflection point" and get some basic information on room acoustics, so people can have a proper conversation with you about how to solve your problem.

@OP - curtains on your windows and acoustic treatment correctly applied to the available surfaces.

The point of first reflection is where the off axis sound from the loudspeaker meets the wall and reflects off it. That is where you apply treatment to the sidewalls.

The aim of acoustic treatment is to stop reflected sound reaching the listener's ears out of phase and confusing imaging etc. It can make the sound appear bright due to the excess of reflected energy.

Dense drapes.  Ask your sig o. to choose color. (This is not hard.)

Thanks to all for your many suggestions and comments. 
And yes, I should have done a bit more research before asking about reflection points. My apologies.
