Ethan, Thank You for responding.
I've downloaded the tones and graphs from RealTraps (pretty cool place, you may have heard of it.

)
I ran the tones and charted my graph. I got peaks and valleys just like you'd expect. Now, as an acoustic newbee, "Now what". Do I buy a BFD and adjust the drivers, or do I treat the room.
I went with the room treatment as my next focus. I put some effort into the ceiling with the "creative use of drywall", and 2X2 USG tiles.
Here's a few pics to give an idea of where I'm at.
