I wanted to create a speaker with 360° Sound, not the standard Sound.

This is, what I got after several attempts.
The photo shows the first try on the left (not published), the subwoofer (other project) and the speaker, you can find here on the right)

It's no usual speaker, but it sounds good.
Needs a Subwoofer (other project will follow).
I used a Visaton vs-frs8m for other speaker please check if they fit.
Speaker-Space is 73mm Diameter, 5mm Mounting-Holes are on Circle with 83cm
Fits perfect for the vs-frs8m.

Needs 4 screws for the speaker 4mm, 4 for the chassis (3mm x 12mm or similar)
Printed on my X1C all parts fit together without glue.
you also need speaker-cables. I used 2 adapter with banana-plug (holes on the backside of the speaker)

It's a simple print. Use 40% infill for the speaker-holder, for the other parts 15% is OK
The adapters needed raft, the other parts did print without.
No support needed.
The inner part of the pyramid is hollow,

Need a subwoofer for this speaker?
