The original design, as pictured is a better performer than the more frequently seen "W" design. The bass is stronger on the original design.

The original design information can be found here

The plans to the second version ( “W” design) can be found here

Here is a link to the original Hartsfield patent

If you are going to the trouble of building a Hartsfield, build the original. Do not waste your time and money on the inferior second version.
