Konus audio Essence
 
Has anyone ever tried to build clones of the Konus Essence? It is the speaker the founder of 47Lab uses nowadays, a design by a Bosnion importer of their Gaincards.

Are there any building schematics to be found?

I am planning on building a pair of the Jordan JX92S TL speakers based off the reference design on the Jordan website:
http://www.ejjordan.co.uk/enclosures.html

It has the same exact external dimensions as the Konus Essence, but I have heard that the internals are different. Here is the picture of the internals of the Jordan V/TL reference design. The V/TL designation implies that if you make the dashed lines solid, it is a TL speaker design, and if you don't, then it is a vented speaker design. I am going to build a pair in a month or so, after I finish up some other projects. I got my drivers in the mail today. They are good looking.

It seems that the design on Jordan's site, is exactly what this Bosnian designer claims to have developed himself...

Check out this site :

Somehow 47Labs is attractive to clone builders! Even in their own ranks... ;)

Here is a review of the Konus Essence from AA:
http://db.audioasylum.com/cgi/m.pl?f...eakers&n=79381

I have read other places that while it is similar to the Jordan TL reference design, there are some internal differences, and that Sead Lejlic started with the Jordan TL reference design and made a couple of small changes to it that improve the sound of the speakers. Also, their cabinet is supposedly dipped in resin, which makes it much more rigid...

I am going to make a pair out of mdf.. will only cost $25 in wood to see what they sound like.

It seems similar to the gaincard... take a decent component with a reference design from the manufacturer, and tweak it to make it a bit better and market it for a large sum of money.

Yes, the speakers look identical to the speakers on the Ted Jordan's website - but only from the outside.
I've been listening to the Konus Audio Essence speakers (not 47 labs) for more than a year. The only thing I can say is that they sound much better than the speakers made upon the internet plans. I know that because I tried both speakers in my listening room. It is true that Jordan's DIY speakers sometimes sound "hollowish and cabinety", but not the Essence - not even a trace of that!
The wonderful Jordan 92S drivers are the same in both cabinets but the Essence is far, far superior!
Best wishes and Happy New Year!

You could try and varnish the inside with a couple of layers. I don't know if that would affect the sound very much, it might work as an extra, strengthening layer (like plywood).

I would use 25mm MDF instead of 18mm as indicated on the Jordan plan. At least for all the outside walls.

Totem Acoustics uses veneer outside AND inside. That will increase rigidity too.
