The Jordan Eikona full-range drive unit is suitable for a variety of loudspeaker enclosure designs. The Eikona’s carefully balanced specification means that it works well in cabinets ranging from a compact reflex to large, transmission line array capable of reaching the lowest musical bass notes. The inherent scaleability of the Eikona is discussed in full in our Audio Building Blocks series.
Below are the 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 the Eikona – please send details and photos to our Sales address.

We are always happy to support our customers in any way we can when they are building one of our published designs. Or if you have a design of your own and require input, send us an email.
Kits and complete cabinets for the Reflex 7, VTL and DCR are available from Wilmslow Audio.
A compact bookshelf or stand-mount loudspeaker capable of reaching below 50Hz.
A compact, stand-mounted transmission line capable of surprising bass for its size. This is the latest in a series of TL designs, all of which have received excellent reviews from all those who have heard them.
A compact, floor-standing cabinet which is capable of excellent bass response and is easy to build. There are two versions to cater for all levels of DIY skills. Full details are on the Eikona SL blog.
Ted Jordan’s classic VTL transmission line enclosure is capable of superb performance down to 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.
A compact, floor-standing transmission line featuring two Eikonas per cabinet. Although only 826 mm tall, this loudspeaker gives good bass down to 30 Hz. The design is described here and a subsequent blog gives an innovative translam construction, with downloadable CNC cutting plans. AA taller, slimmer version is available as the TL2 with identical performance.
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 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.

Our largest and most powerful Eikona system to date. The TLA is a substantial, transmission line loudspeaker capable of handling the full power and majesty of orchestral music. The line has been carefully optimised for the Eikonas and the design is receiving rave reviews from constructors. Read the design blog and download the construction guide here.
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 specially designed for the Eikona 2 by Jim Griffin. Read more about it on our blog.
