SUBWOOFER
Core Gameplay Experience
Equipped with 20+ precision components, this is a highly engineered mechanical play system that delivers a unique palm-speed vibration experience.
The finely tuned rotor requires careful balancing and precision assembly. When spinning, it generates a deep buzzing vibration feedback in the hand — similar to the sensation of a mini subwoofer.
Even in situations where large spinning motions aren’t convenient, a light flick with the thumb is enough to activate the rotor and feel the subtle, hidden vibration response.
Structural Design Concept
Inspired by the structure of an audio subwoofer, this product features a fully original mechanical design with extremely rich DIY customization potential.
You don’t just play it — you define the feel.
By adjusting the number and material of beads colliding inside the internal chambers, you can create a wide variety of tactile feedback and sound effects.
DIY Play System
DIY Mode 1 — Adjust Beads Inside the Rotor
Each rotor can hold 1–9 beads (3.9–4.5 mm, various materials).
By increasing or reducing the number of beads, you can fine-tune different levels of drag and tactile resistance.
DIY Mode 2 — Adjust Beads Inside the Main Body
In addition to the rotor, the main body contains four internal bead slots.
These slots support 3 / 4 / 5 mm tungsten steel beads, magnetic balls, and more, allowing further tuning options.
Different configurations unlock multiple play styles, including:
- Silent mode
- Acceleration feedback
- Ratchet-style tactile response
- Variable speed sensations
DIY Mode 3 — Install Glow Beads
Placing glow beads inside the rotor creates stunning light-and-shadow visual effects while spinning, adding a dynamic visual layer to the play experience.
Materials & Visual Aesthetics
The standard configuration includes:
- Titanium or Zirconium main body
- Engraved stainless steel rotor
- Additional composite material components
Under sunlight and artificial lighting, the mix of materials creates rich surface layers and shifting reflections, producing a futuristic and visually dramatic appearance.
