I don't think he has all his calculators online yet. Notice in the right frame on the page the following info posted :

Latest Updates

• finally finished the instructions for the 1/4 wave flared vent t-line/horn/bass reflex enclosure calculator...only 13 more calculators to go 2010-01-05
• i know i haven't updated the site in a long time. seriously though...i will at least try to finish up the calculator instructions ASAP 2009-10-15

Looks like it might be a while before he gets around to it.

The above design posted January 5th does look interesting. Too bad he doesn't have no info posted about it, because I can't find out anything about on a google search.
