JBL wooden speaker stands - dimensions?

[Dark Knight]

I have seen some wooden JBL speaker stands. They may be described as a "lincoln log" design because there are only four pieces of wood and they secure through only two notches (see figure below). They are enough to elevate the speakers off the floor with a slight tilt upwards.

If any one owns these could you kindly send me the basic measurements. They went on eBAY for $115. I love JBL as much as the next gear head but....

I think the design may be simple enough for even me to build. Four pieces of wood and two well placed notches on each. $115??? Am I missing something?

Best Wishes All
