Jordan_Eikona_2_BBC_DSC_2410

The Jordan Eikona 2 is designed to suit a range of enclosure designs and alignments. It will work well in a sealed enclosure of 4.5 litres, giving good bass to 85Hz in a very compact cabinet (as in the BBC LS3/5a cabinet above). Alternatively a metre-high floor-standing, mass-loaded transmission line  enclosure will reach to 27Hz. The inherent scaleability of the Eikona is discussed in full in our Audio Building Blocks blog series.

Below are enclosure designs currently available from us. Other designs are on forums around the web and we’re always interested to hear what people build with our units – please send details and photos to our Sales address.

Eikona VTL

Ted Jordan’s classic VTL transmission line enclosure is capable of full-range performance to below 35 Hz. The 30cm-wide baffle makes it easy to accommodate and maintains a realistic weight to the sound.

The Eikona VTL received an impressive testimonial which features on our blog and there is background to the design in this article.

Eikona 30 MLTL

As the name suggests, this is a shorter version of the 38 MLTL, sacrificing a small amount of extension of a more domestically-acceptable size. It was designed for the Eikona 2 by Jim Griffin and you can read more about it on our blog.

Eikona 18 MLTL

This design blurs the line between a conventional reflex and an MLTL transmission line. It is a 45 cm high enclosure with an internal depth of only 12.7 cm. It is designed for stand- or wall-mounting.

Eikona DCR

The Dual Coupled Reflex is a wide baffle enclosure for a pair of Eikona 2 units. The use of an extra Eikona driver increases sensitivity and headroom. The 12 ohm load is ideal for valve amplifiers. The enclosure can be floor-standing or wall-mounted. You can read about a stunning floor-mounted build and listener comments on our blog.
