Looks interesting! The auction claims that they are easy to build.
"Cabinet is very easy to build. All you need is circular saw drill, and a router."

I have build 3 pairs of Speaker Labs "K" horns and they are not easy to build!
We had a table saw, radial arm saw, plane-joiner in addition to the above mentioned tools. This would be hard for just one person to make this cabinet, but I you have two nice corners in your room and want good base horn then give it a go! John
