Zen Acousta

Very nice work and a stunning design too.
Too bad Sweden is so far away from Germany, it would be such a cool thing to compare yours when they're ready with my pair of Dallas II (also with the FE206En).

From one of your previous messages:

> I use 12mm baltic birch plywood (which cost an arm and & leg here in Sweden).

I wonder why is that so? A lot of birch comes from Scandinavia or North Europe anyway.

I've been wondering the same... I even had to order them by special request, the only plywood I could find otherwise was made from pine and not nearly as good-looking or smooth.
 
KoHo,
If you add an 8 liter volume x 6 in deep driver chamber connected to the main horn (at same location) with a 2.5 in dia hole through 0.5 in thick plywood that connects the chamber to the horn, you can extend the bass down by about 10Hz and smooth out the response somewhat. This is with Alpair 12.3P. I think the Alpair will be less bright and more balanced than Lowther, and less expensive too ;)

XRK~
In preparation for this build, I came across your suggestion utilizing an 8L driver chamber w/ Alpair 12.3P in this design. I would like to implement this into an upcoming build (based on the improved sims) but I'm struggling with visualizing the layout, as described.

Could you please provide a few more details about how/where the driver chamber needs to be installed + location of the 2.5"D hole?

Thanks for all your help.

They are finally at home & playing some sweet music for me :)

The only remaing thing is to touch up a few scratches that my brother-in-law managed to give them when he drove them home for me, and attach the wooden rings I will have around the elements to hide the screws and metal parts of them.

I have read somewhere that the Fostex needs up to 100 hours before they start to sound really good, so I better start listening to them now!
The first song I played on them was Over The Rainbow by Israel Kamakawiwo'ole, and to my ears they already sound amazing!

A huge thanks to KoHo for sharing the drawings to these awesome horns! :worship:

Yes, it's different, natural resonate.

Soft cords and not contatct with the floor are big part of Zen Acousta magic mojo.
Frequently one neglected paramenter of horns users.
Varnish, painting or natural oil can bring subtle differences to the music as well.
It's wood natural material fibres micro scale vibrations.
Violin instrument producers made lot of research about this influence.
