Eikona MiniLine Loudspeaker
The Eikona MiniLine is a compact, transmission line loudspeaker designed to be stand-mounted. It provides
surprisingly deep bass for the size of enclosure and yet is compact enough to be accommodated in any
domestic listening room or small monitoring studio.
The MiniLine uses a Jordan Eikona full-range driver in a coupled cavity transmission line, carefully optimised
to offer extension to below 50 Hz. The Eikona handles all frequencies from bass to treble, without the phase-
distorting presence of crossovers. This gives the MiniLine unparalleled stereo imagery and musical coherence.
This cabinet is straightforward to build but to make it easy to adjust the internal damping, we recommend
fitting a removable back panel, as shown in the plans. The battens should go along both sides as well as top
and bottom panels, and should be made of 18 mm square section beech, oak or birch ply offcuts. Only use hard
wood - softwood is not suitable. The panel should be sealed with foam draught excluder and screwed in place.
If you prefer to permanently fix the back panel in place, you can omit the battens and reduce the depth of the
final line section to 45 mm instead of 50 mm.
We highly recommend you use Mundorf Angel Hair for the line damping material. It should be well teased
out and spread evenly throughout the cavity and line sections. Angel Hair expands after placement and will
hold its position without further support.
Internal wiring should be taped in place and fixed with glue or silicon sealant (not pins). The aim is to prevent
it from buzzing; once the cabinet is sealed, opening it to fix down a cable will be difficult.
We recommend fitting grilles over the Eikonas to protect them from enquiring fingers. The line exit should
be fitted with an acoustically-transparent cover to deter wildlife from entering or the Angel Hair from escaping.
If the MiniLine is to be stand-mounted, we suggest a stand height of 600 mm.

Corner battens are 18 mm square and run
along sides, top and bottom of the rear panel
to make the rear panel removable.
If a removable rear panel is not required, omit
the battens and reduce the depth of the 50
mm line section to 45 mm and adjust the
PLAN external depth to match.
