japanese speaker plans

I found a web site by a guy in japan with dozens of rear loaded and loudspeaker plans. They werent very large, maybe the biggest was 24"-30". It was a personal site. Computer crashed and lost the book mark. I dont know how I found it, but ive been searching and searching and nothing. Sorry dont have any other hints on whats on it. But the plan were pretty detailed. If anyone knows of the site or something similar can you please help me. Thank you.
 
Or maybe it was the "nifty.com" site?

Just got the Fostex craft handbooks -- absolutely mind-blowing to see the designs in there. Very inspiring and some of the designs are just bizarre, and I've never seen any reference to them on any English-language site (nor any Japanese site, really). Way beyond Swans, Nessies and the regular backhorns we often see. Lots of robot-style cabs, for example, and furniture (like tv stands).
