Hi Tyimo, the plans are in this thread at the FR forum.
Ron Clark (or is it Clarke) designed it in inches to use .700" plywood. Ron's a very sharp acoustic engineer who uses many programs to design with and is putting the finishing touches on a design that is out of this world. The Dallas II is designed for the Fostex FE206E but can also use the 208 sigma by omitting a piece of the filter chamber. Jeremy used a CAD program to transpose the design to metric and may be willing to share those drawings with you.
Onur is also a member here and is very innovative. He likes to use a program called A J Horn and since he's from a Turkish university his plans will be in metric. His Singular design seems to be his most popular.

Thanks Squalor!

I have the DallasII plans, but I still can not find Onur's Tannoy IW8 plans.

Default see the Singular link

The cabinet which Onur used with the Tannoy drivers is the "Singular" with no changes or modifications. The link that I posted should take you to the design which Bert Doppenberg uses. I will double check it myself. Regards Moray James.

Have you seen this design? I have not built this myself (yet) but I most likely will. Very easy construction and no fancy damping to deal with. Best regards Moray James.

Simplicity, easy to built and very good balanced in combination with drivers having a Qts between 0.3 and 0.6 from which you can choose. If you like your FE206E's in a reflex then you will love them in the SINGULAR for its more efficient loading over a wider range. If you like your Lowther driver in a reflex then you will love them in the SINGULAR even more...

The basic design for this system was initiated by Onur Ilkorur for his own AERmkI drive units, providing a pretty efficient loading over a wide range. The system is not a Bass Reflex which is only efficient for half an octave, it is not a Transmission line with the need of much damping material to dampen all resonances, it is not a TQWP or ML-TQWP but it is a combination of all these systems resulting in a wide-band resonator effective from 40Hz up to 250Hz.

The system is tuned for maximum efficiency using as less damping material as possible, no hornyness or honkyness coming from these using only the few 30mm thick sheets of BAF as shown in the drawings. The only thing you have to find is a good place for them in your room, for more body and bass simply place them closer to the back wall or even in the corner (lowest Q drivers), if there is too much bass or "boom" then simply pull them out of the corner or move them further away from the back wall until you have found your optimal balance.

Below you will find the drawings for our SINGULAR DIY system. Thanks to Dave Johnson (who made these). Click on the link below to download the detailed drawings:

http://www.diy-systems.com/wwwboard...try.php?id=9586



The best material to be used for this system is 18-19mm Birch Ply, as always with full-range drivers, this material gives the most natural tone. The few 30mm thick sheets of BAF should be placed as shown in the drawings.

Default do the search

This is wierd, I went and did a singular search here on diy and found my post about the singular. When I clicked on the link for the singular it took me straight to all the info. However when I copy it and re post it and then try it again I get an error message.
So do a search under Singular and find the thread on a fostes fe206e (that's how it was spelled and finf the link and it should work for you too. Regards Moray James.
