GEOMETRY

The voice coil of the Semisphere functions in a high-precision gap between the two motor components. This spacing was optimised through Finite Element Analysis during the design development of the Semisphere. The result is near-ideal geometry.

The faceplate recesses the voice coil of the Semisphere deeper within the speaker in order to align it more accurately with mid-range drivers.

 

The rear end cap has an internal surface architecture that channels exhaust gas towards a “bullet” centre . This then scatters the signal as it reflects it in all directions, using a similar priciple to a silencer.

STRUCTURE

The composite construction of the Semisphere dome affords the tweeter  with the characteristics of a hard-dome tweeter while retaining the damping qualities associated with a silk dome tweeter.

The faceplate has a significant structural role, forming the energy interface between the Semisphere dome and the air.

The rear end cap ensures high integrity structure in the tweeter system. It forms a large chamber for exhaust air created by the dome and voice coil.

HEAT TRANSFER

A fundamental consideration in loudspeaker tweeter design is heat transfer. In the Semisphere, where the mass of voice coil has been minimised in the pursuit of improved dynamics, effective cooling is vital.

 

Highly conductive, massive components in close proximity to the voice coil, including the faceplate and rear end cap, act as highly efficient heatsinks to provide unprecedented levels of cooling. This ensures the highest performance even after prolonged and intensive use.
