Cantilever Domes – Resonance-Control Footers
Mostly air. The mighty insulator. A dome. The Hercules of geometry.
Cantilever Domes combine the two — creating the lightest, strongest way to control vibration under speakers, amplifiers, and turntables.
The Secret of Strength
The dome of Hagia Sophia in Istanbul has stood for nearly 1,500 years — through wars, quakes, and empires. Not because it was a giant block of stone, but because it was light and hollow, built from pumice and thin clay bricks. Geometry carried the load, not brute force.
Cantilever Domes follow the same principle. Each is printed with a gyroid lattice at 15% infill — meaning 85% of the structure is air. Like Hagia Sophia, they’re light yet immensely strong. Geometry does the work, dissipating vibration instead of storing it.
Why Footers Matter
Every piece of gear vibrates: speakers push against the floor, transformers hum inside amplifiers, turntables pick up the smallest tremors. Left unchecked, those vibrations smear detail, blur imaging, and rob music of life. Footers exist to fix this — but most do it wrong.
Two Schools of Thought
Drain to the ground: Spikes and heavy cones dump vibration into the floor, but the ground isn’t silent — energy reflects back and hardens the sound.
Isolate from the ground: Rubber, sorbothane, and springs try to cut the connection, but they over-isolate, storing energy and smearing timing.
The Cantilever Dome Approach
Mostly Air
85% void, limiting vibration pathways.
Dome-arch Geometry
Splits force and vibration into harmless fragments.
Gyroid Core
A continuous 3D lattice that diffuses energy in all directions.
Inert Composite
Doesn’t ring like metal or collapse like rubber.
The result is balanced resonance control: grounded without glare, isolated without smear. What you hear is clarity, dynamics, and tone — untouched by resonance.
Proven Strength
Don’t let their feather-light weight fool you. Four 1-inch Cantilever Domes supported a 200 lb load without flexing. Pound for pound, no structure is stronger than a dome — whether in a cathedral or under your speakers.
Even an eggshell proves it: fragile by nature, yet able to bear surprising weight because of its domed shape. Cantilever Domes apply the same principle — finesse over brute force.

❓ Frequently Asked Questions
1. What are Cantilever Domes made of?
They’re printed from an inert composite using a gyroid lattice at 15% density — meaning 85% air inside. This makes them incredibly light yet cathedral-strong, with no ringing like metal or mushiness like rubber.
2. How do they actually work?
Air is the best insulator against vibration. Domes are the strongest structure pound-for-pound. By combining the two, Cantilever Domes minimize vibration pathways while splitting and dissipating energy through their dome-arch and gyroid geometry.
3. How do they compare to spikes or heavy footers?
Spikes and heavy blocks try to “drain” vibration into the floor — but floors aren’t silent, so energy often reflects back. Rubber and sorbothane “isolate,” but they store energy and smear timing. Cantilever Domes finesse both approaches: light, rigid, geometrically perfect, and resonance-free.
4. What gear can I use them under?
Speakers (bookshelf or floorstanding), amplifiers (tube or solid state), DACs, preamps, and turntables. Basically, anything that vibrates or needs stable support.
5. How many do I need?
Four Domes (one at each corner) is standard. For especially large speakers or racks, you can add extras as needed.
6. Will they support heavy gear?
Yes. In testing, four 1-inch Cantilever Domes supported 200 lbs without flexing. Larger sizes only increase capacity.
7. Do they need pads for hard floors?
You can use them bare on carpet, or add optional felt/rubber pads if you’re placing them on hardwood or tile for surface protection.
8. Do they change the voicing of my system?
No — they don’t color the sound. Instead, they reduce smear and glare caused by vibration, letting your system’s natural clarity and dynamics come through. They sound like air: nothing.
Closing Tagline
Cantilever Domes: Not solid. Not squishy. Just 85% air.
