Between March and May 2025 the installation was build.

All the (audio)connections, screws and the wiring.

Fibreglass fabric and epoxy resin to protect the shells (and give them a nice colour too).

And finally: we need a sound source. A portable setup and battery powered.

 

It turns out everything fits into my car, which is fortunate. On the next page the first testruns outside are documented.

 

 

We cut the segments out of polystyrene using a hot metal wire.

It's a three legged species...

The shell consists of nine different segments. So we had to saw nine different moulds out of aluminium.

The pieces were glued together. The last part of the shaping was done with some rough sandpaper.

The heart of the machine. It can turn 360 degrees and it has a voice.

One afternoon was spent on transporting this piece of sewer pipe. This was going to provide the casing for the speakers.

The final model was completely designed by Pieter Verhees.


Based on this design we built the first speaker, that I tested outside. It worked remarkebly well, we only did some minor adjustments. So soon after the first one we built seven more...

The slideshows below (navigation arrow in the lower left corner) are meant to give an impression of that process.
