Here are some pictures of my Woden Design Dunideer build. It uses the Mark Audio Alpair 6. So far they sound great. They excel at jazz and acoustic music. Nice big soundstage and fantastic dynamics. They are a pretty easy build as well.

Glad you're enjoying them. That's a really nice build. :)

To answer a couple of the general queries:

-Essentially, driver efficiency in back-loaded enclosures doesn't change. They don't operate over the entire audible frequency range, just a narrow portion thereof, preferably from the desired lower cut-off down to the driver's mass corner frequency. Therefore, while you can boost things considerably in this region, it is only in this region.

-No compensation for step loss is required. The A6 already largely self-corrects for step loss, & the horn provides the rest.

Hi All,
Here is a link to the article I wrote for Hifizine about this build. Any comments would be welcome.

Nice build, it appears that you have the Gadlee's Nathan in the background, I know they are completely different type of speakers, but how does the Dunideer stack up against the Nathan?

The Dunideer throws a huge soundstage and is a really fun speaker. It was also a super fun speaker to build. That said I am not sure I could live with any 3-4" single
driver speaker forever. I need more output. The Nathans are fantastic speakers that I really love.

Is it just the lower output and perhaps lack of bass (after all the drivers are only so big)?

The Gedlees are not made to play low. So both require a sub. I sort of suck at describing the differences. I would take the Gedlee everytime if I had to choose one. To be fair I spent $ 2k+ on them and less then $300 on the Dunideers. So not really apples
to apples. Luckily I don't have to choose one. Sometimes you feel like a nut sometimes you don't.
 
=Although if you want a large horn for the 5.2 / 5.3, we can do one.

The Frugel-Horn Lite is a superb smaller horn. I think Scott and i have chatted a bit about a larger rear mouth Megalith horn for these (we certainly did for the (sadly) underappreciated, and NLA, Alpair 6.2s.
