Building process:

The first part of building process was to pencil out of the cut outs of the drivers and the binding posts as these were the difficult parts in terms of drilling involved, as all the 25mm MDF surfaces had already been cut to shape with the dimensions in the previous post. As you can see in the image below, here is the pencilling of one of the drivers being done with a 185mm diameter that was distinguished in the driver specifications manual. The two circles were cut 120mm from the top to the centre of the circles which was distinguished in the speaker dimensions on the previous post.

After the driver circles had been cut out the next process was to cut out the squares for the binding posts to comfortably sit in. The idea in terms of where to place these was towards the corners near the open ends of each enclosure. This was so that it did not affect the reflections behind the drivers. The pencilling and cut outs can be seen in the images below.

Once the cut outs had been done, the next process was the pencil all the walls onto one of the enclosure sides as an easier guideline of where to place the glue and nails in order to thoroughly support the speaker in order to have sufficient rigidity.

Once the pencilling of all the walls had been done, the process was to start gluing and nailing together the inner walls starting with the front and rear faces and then onto the inner slants. As seen in the images below.

Once all this had been done, you can begin to see the shape of the two mirrored enclosures now in the image below where the fixing of the bottom could be done to begin to close of the enclosure.

Once both the top and bottom panels had been securely fastened, using an air pressure gun to clean the MDF dust away from the inner walls and surfaces, the damping can be done before placing the last side panel onto the speaker.

In the images below you can see the damping whereby the acoustic filling is placed in the first 1/3rd of each TQWT enclosure. With carpet felt on the majority of surfaces, however more predominately towards the rear of the here the drivers would sit to maximise the damping of internal box resonances as well as all the corners.

One slight adjustment here was that the acoustic filling needed to fixed in some way to stop it from falling further away towards to the open end. As you can in the image above to the right, a small light felt fixing was glued to help fix the acoustic filling into place. At the same time making sure in did not entirely block the whole line.

After this had been done and all the available 2.26796 kilograms of acoustic filling equally shared into each enclosure and 2.5 square metres of carpet felt in each enclosure, the 30AWG wiring could now go into each enclosure running from both circles to their respective binding post holes so that soldering could commence once the final panel and outside painting of the enclosure was done. Once the outside white painting had been done to give the speaker a slightly better look, and help cover the nail holes. In the images below you can see in side the circles where the majority of damping is and the cabling hanging out before soldering them to the back of the drivers. The yellow tape helped distinguish the positive terminal with the other being the negative terminal.

The same can be said for the binding posts where the other ends of the cabling is viewable in the images below.

Once this had been done, the next step was to to solder and fix the driver units, along with the soldering and fixing of the binding posts.

Now the speaker can be seen above with the driver units and binding posts all tightly secured in. Now the the next and final step was to use 2 of the 30 AWG wiring cables from each binding post and connect them to the back of the Topping TP22 amplifier which can be seen at the moment of the top of the speaker in the image above.

In the image below you can see the outside connections, that at this point look slightly messy however at a latter stage once it is left in a room, the intention is for the cabling to neatly fastened. However, as after this the next step is to test the speaker the moving of the speaker would require significant help as the speaker does weigh a considerable amount, and to stop the cabling from catching anything the binding posts making it easily un-screwable.
