loudspeaker plans


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 2 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.

Cut Plywood Company can supply high quality Baltic birch or MDF panels cut to size for your loudspeaker project with cut and rebate holes for drive units. Contact them direct for prices. Kits for some of these designs are also available in the UK from Wilmslow Audio and BK Electronics.

Eikona Reflex 7

A compact bookshelf or stand-mount loudspeaker capable of reaching 55Hz. Ideal as a monitor or satellite system.


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 further background information to the design in this article.


Eikona 38 MLTL

This is a 1-metre high mass-loaded, transmission line designed for us by Mark Dikovics. This slim enclosure is -3dB at 27 Hz and is capable of handling the full orchestral range.


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 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/tube amplifiers. The enclosure can be floor-standing or wall-mounted. You can read about a stunning floor-mounted build as well as listener comments on our blog.


Eikona Linear Array Reflex

This design is discussed in full in our Audio Building Blocks series. The 1.2 metre tall enclosure houses 4 Eikona units, giving 92dB/watt sensitivity and 400 watts power handling, plus all the imaging benefits of a line array.

Eikona Triangular Array

This is our latest Linear Array design. It features four Eikonas per speaker in an alegant, sealed triangular column. The enclosure shape has a number of benefits which are explained in our design blog. The system is aimed at high-end home cinema systems and hi-fi systems where the speakers need to be discrete but capable of concert-hall performance. The system is ideal for use with a sub-woofer which can be blended in below 70 Hz.
