KODEX

1. Prepare the detail boards A, B, and C. For this purpose symmetrically cut off two triangles 123 x 125 from the board A of the parts list. Make a cutout of 200 mm diameter in the centre of board C. Round off one side of board B neatly and chamfer the other side approx. 45°.
2. Chamfer one side of the bottom of the midrange cabinet approx. 45°.
3. Per cabinet prepare the five small sound guiding and reinforcing boards with two 45° chamfers (also in this case the angle need not be too precise, as it is no problem to fill out the resulting gaps in the direction of the sound channel).
4. Prepare the large sound guiding part A+B. Adjust A at the lower edge of B exactly in the centre and glue A on the „short” surface of B.
5. Drill a cable inlet in the rear wall of the midrange cabinet.
6. Glue all other boards and the AB part to a lying side and glue them to each other (you may proceed in two steps: first the outer boards of cover, bottom, front wall, rear wall, and the midrange cabinet, and then after drying, the inside sound guiding and reinforcing boards which then are already supported and which can slightly be smoothed in an inconspicuous way where it may be too narrow).
7. Then glue on the second wall and weight or clamp it.
8. In the meantime smooth the front wall and the front edges of the side boards to obtain an optimum even cutting area.
9. Make the recesses on the front wall exactly according to the drawing (also see the detail drawing). ATTENTION (I): the cabinets of a pair must be built up mirrow-inverted! ATTENTION (II): the area of the oval recess which includes the mid-high range arrangement is slightly more difficult. Certainly, it can be recommended to insert a dampening fleece or felt later on but it is not of essential importance. It is certainly admissible only to recess the bass speakers and the tweeter. The optimum flat flange of the MSH-116/4 even allows easy mounting and there will be no effect on the sound by the protruding edges.
10. Make the cutout for the terminal on the rear side.
11. It is recommended to chamfer or round off the front vertical cabinet edges.
12. Surface treatment as desired.
13. Build up the crossover network and provide it with connection cables of sufficient length for all speakers and the terminal when mounting the crossover network behind the lower bass speaker. The cable for the terminal is laid in the sound channel via the upper edge of B.
14. After mounting the crossover network and laying the cables, seal the inlet to the midrange cabinet well.
15. The chamber behind the bass speakers is fitted with wedge moulded foam pads glued on (do not cover any further the tapering to the sound channel and of course the cutout in C!).
16. Completely fill the midrange chamber with the special dampening wool MDM-3 until the midrange speakers press together the wool when they are screwed in.
17. For further dampening see the special text „Dampening of the KODEX” page xxx.
18. Solder on the speakers and the terminal and screw them in.

The Dampening of the KODEX
Optimized at its best means individually optimized bass sound!
Even if the KODEX is no „purebred” transmission line speaker system (in the basic sense real TMLs work similar to organ pipes which are tuned to a sound which perfectly completes the bass reproduction of the bass speakers downwards), it includes in any case a characteristic of this type of speaker system which has to be observed in any case but which also entails great chances of optimizing the sound.
TMLs react in a most sensitive way – you can also say in a most effective way – on the dampening of the sound channel.
In this case, it is important WHERE the dampening material is inserted as well as WHICH type of dampening material is used and above all in which DENSITY!
For the KODEX this means a great variety of individual possibilities of matching the bass reproduction to the individual taste and of course to the individual room of hearing. With some experience every hi-fi fan will get to know the influence on the bass sound at the place of hearing by different rooms and also by different set-ups within a room. With the KODEX it is possible to bring the cabinet itself into play without the need to use quite a different one.
You will hear immediately whether you change the quantity of the dampening wool or move it in the sound channel. We can only recommend to make it as it pleases you most. This may even result in dampening one speaker cabinet differently from the second, depending on the set-up.
It is important that due to the powerful and wide midrange of the KODEX you need not worry about sound interference in the true sense and that due to the extra stable mechanics the KODEX bass speakers practically follow each change. Therefore, you can proceed in the bass range as desired.
To create a solid starting base, we have of course developed above all a good solution regarding the measuring technique. If you are already satisfied with a solution which is very good, you will find it here.
