Why marble sounds.
Stone is not an aesthetic whim: it is an acoustic choice. Here is what changes when the cabinet is natural stone rather than wood.
The cabinet must stay still
A loudspeaker performs at its best when the walls of the cabinet do not move. Every vibration of the walls adds to the sound of the drivers, out of time, and colours what you hear. An eighteen-millimetre wooden panel flexes and gives that energy back; the mass and stiffness of stone hold it in check.
Stone is the structure, not a veneer
In most so-called marble loudspeakers the marble is a thin plate glued to a wooden box. Not here: the stone slabs are the cabinet. It is the difference between a clad piece of furniture and a monolithic object — and you can hear it.
Mass, geometry, damping
Stone alone is not enough: how it is cut and held together is what counts. Internal geometry, joints and damping materials govern what remains of the vibration. That is where the design truly lives, not in weight alone.
