Jordan Eikona 2 Designs

I agree, changing the driver to the narrow baffle rather then the wide should have minimal if any on bass response...

 

[scottjoplin]

The wider baffle supports the lower frequencies

Planet10, I don't know if it's possible, but I would love to see a variation of the design: Mark Audio Alpair 10.x/FF165wk compact Floorstander for the Eikona 2. I love the look of that cabinet, especially the 5* back sweep on the front baffle. Its a small footprint and with the Eikona 2 I would assume you could really get some good LF response with that design. I realize a similar cabinet plan designed originally by Jim Griffin (30MLTL) is available, but I prefer the look of the "compact Floorstander".
I think this would be a cool little project and would appeal to many DIYers.

Email me. I’d have to do the same trick i plan on using with other drivers need less than the 13 litres that a minimal CFS config requires.

Hi Colin,

Do you recall the BSC filter values recommend for the VTL, I couldn't find them on the Jordan website.

Thanks,
Paul

The BSC values for the JX92S VTL were R - 4.0 Ω and L - 2mH.

Regarding the wide/narrow MLTL30 cabinet:

Jim originally designed it with a deeper aspect but prefer wider baffles as the speakers sound 'fuller' with a better upper-bass/lower midrange.

However, if going for a narrow baffle don't use the design as published on the EJJ site (that baffle is too narrow) but go back to Jim's original spec of 18cm wide x 19.75cm deep (internal). All other details remain the same.

Excellent, already have the parts in my parts bin. I'm making a VTL like design to use with my old JX92s, since I upgraded to the Eikonas.

Thanks Colin

I made those with removable back panels so I can also use them OB, I've probably said

 

[Colin]

In case anyone else is working with the JX92, the full list of passive networks given on the website was:

3 litre enclosure - 4.7 Ω and 1 mH

8 litres - 4.0 Ω and 1.5 mH

VTL - 4.0 Ω and 2 mH

Presumably you're not able to use them at very high volume if run full-range like that?

 

[PJN]

Yea mine too, it's a MLTL, removalbe back panel to allow stuffing changes/tuning, imbebded magnets underneath the veneer for the grills. I'm almost ready to finish the veneering and final finishing/tuning. I'll post some pics and impressions in a few weeks when I should be done.

 

[scottjoplin]

I don't run them full range no, xover at ~100Hz to bass speakers, don't listen loud either, works surprisingly well, the sides probably help a bit too, effectively widening the baffle

A little late to this query but our Eikona SL is a recent design on our website which is a compact floor-standing enclosure with sloping baffle. The baffle slope makes enclosure like this look very neat and room friendly but does introduce angles which some constructors find tricky; for that reason we also have the design as a flat baffle version.

Nice job, looks a neat design, especially if the angled baffle can be retained.

 

[Colin]

Cheers, Scott.

An early customer build was a foam board version of the sloped cabinet. It sounded remarkably good for a floor-stander which was easy to pick up with one-hand!

So far, others builds out there seem to be the straight version.
