Steve stated it well. I like this video for helping to understand how different treatments effect sound.

Sometimes that is all you need to break up the reflections.  Different placements will give you different results.   There are 3 pairs of opposing surfaces, start by dampening one surface of each pair with a minimum of squares.  Try a few different placements.  You'll be surprised at how much effect a little change can have.   Crossing the line from an even, resonant sound to dull and muffled comes kind of suddenly.  Remove that last square, and fine tune by experimenting with the placement of the remaining squares.  Sometimes dampening the corners is a good place to start.

Price is great, but seems like if you get what you pay for, will these actually be any good. I’m thinking maybe 24 - 36 squares as well as corner bass traps.
