Masaaki Takenaka's Horn links page rescued from the Wayback machine

These horn speaker links had been on my 'linkees' page for ages, and a lot of the links themselves were outdated. So when I found the page had disappeared I fished it out of the wayback machine with the intention of keeping it forever safe here. The original work was done by Masaaki Takenaka who himself built 'angular spiral' speakers.

My intention is to group the links, put a local copy on my own site where the link is dead (using the Wayback machine) and update those I can find back.
If your work has been placed as a local copy (under and you want it removed a simple mail will do the trick. If you want a link added a simple mail will likewise do the trick.

The 3D-Spiral Horn Speaker Building

Horn Links last updated by Masaaki Takenaka on 23 Nov. 2006. Are there better ideas than the 3D-Spiral Horn?

3D-Spiral Horns

Labyrinth speakers

Masaaki Takenaka has built a unique speaker named "labyrinth" . This is an extension of the "angular spiral" concept devised by himself.
