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 litres (including driver), giving good bass to 85Hz in a very compact cabinet. An example is 5.5 litre BBC LS3/5a cabinet above, which featured in our blog). 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 as plans 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.

A compact bookshelf or stand-mount loudspeaker capable of reaching below 50Hz.
Ted Jordan’s classic VTL transmission line enclosure is capable of full-range performance to below 35 Hz. The cabinet is 30 cm wide but only 10 cm deep, which makes it very easy to accommodate.
The Dual-Coupled Reflex is a wide baffle enclosure for a pair of Eikona 2 units, designed by Ted Jordan. The use of an extra Eikona driver increases sensitivity and headroom. Connecting the drivers in series gives a 12 ohm load, which 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.
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. It is a reflex design, intended for use away from walls. For an against-the-wall enclosure, see the Triangular Array below.
This is our latest Linear Array design. It features four Eikonas per speaker in an elegant 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 enclosure is sealed with a QTS of 0.7, which is ideal for use with a sub-woofer.

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.
As the name suggests, this is a shorter version of the MLTL38, 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.
These 2-metre high enclosures are offered in response to a number of requests for a larger, horn-type design and you can read more about them on our blog. Two plans are offered, using either single or dual Eikonas. They are designed to operate in room corners, with the output of the line firing towards the ceiling.
