HiFi Speakers Pendulum Stand : Vibration decoupling system (Watch the video)

This unique pendulum-based loudspeaker decoupling system employs suspended support stands designed to fully isolate the speaker cabinet from the table/floor.

By allowing free, controlled oscillation in multiple axes, the pendulum mechanism prevents mechanical energy from coupling into the support structure, eliminating resonance transfer rather than merely reducing it. In doing so, it preserves the speaker’s intrinsic acoustic signature, maintaining mid- and high-frequency purity and ensuring bass articulation remains uncompromised by structural feedback. The outcome is an uncolored, highly accurate sonic image unaltered by environmental vibration effects.

The result is a more accurate acoustic presentation with reduced coloration, improved clarity and stereo imaging.

Tested with 5kg bookshelf speakers, using 4 pendulum stands per speaker. If you need a stronger version for a heavier loudspeaker, drop a like and a comment giving the weight of one of your loudspeaker.

Print Settings :

• PLA 0.4

• 30% infill

• 2 perimeter layers, 8 layers top and bottom

Parts :

• 3 screws M4*12

• 3 threaded brass insert nuts M4*5*5 ( https://de.aliexpress.com/item/1005007830491580.html )

• 12cm * 3mm nylon rope

• 5cm thermorétractable tube around the rope for the required dampening of 0.05 N×m×s/rad. Make sure its solidly iserted in to top fifaxion of the rope.

Tools :

• screwdriver

• soldering iron + insert nut tool ( https://www.aliexpress.com/item/1005007341986648.html ), to insert the brass insert nuts.

• superglue gel, to fasten the rope knots when the height is precisely adjusted between all your stands.

Inscructions :

• see the pictures

• tip, adjust the rope knots to make all you pendulum stands the same height, and once achieved insert a drop of superglue in the knot to fasten it.
