Hifi Absorber Feet

These printable HiFi absorber feet are designed with the spike principle in mind. They have been tested and are currently in use with HECO Superior 840 speakers, which weigh 19 kg each. This specific design can only be achieved through 3D printing.

These absorber feet reduce the contact area between the speakers and the floor. Additionally, they are engineered to eliminate any direct vertical connection between the floor and the speakers. As a result, vertical vibrations are redirected at an angle, significantly reducing their penetration into the floor. While this is not supported by scientific measurements, it reflects the subjective experiences of my neighbors.

It is crucial to print these using the settings specified below. Otherwise, they may end up being too soft or too hard. The Fuzzy Skin setting is especially important for this print! The fuzzy skin allows the interior-facing walls to connect and form a supportive structure. I highly recommend using the provided G-code, which includes a configuration that prints four absorbers in a row on the Prusa MK3.

These absorbers are the result of many prototypes. Please let me know if you have any improvements!

Specific printing advice!

• Print with some kind of hard TPU (D58). I used this one from extrudr.
• Print in Vase-Mode
• Print with 0.3mm Layerheight
• Print with fuzzy skin settings: thickness 0.1mm; point distance 0.2mm
• Enable cooling!

All these settings are pre made in the .3mf file. Check them out by opening the file as “project” in PusaSlicer. With these settings 4 of them easily support my 19kg HECO speakers + a cat sitting on top.
